二氧化碳相对分子质量：CO212+16×2=44

答：carbon dioxide的意思是碳氧化合物，又名二氧化碳。二氧化碳化学式为CO2，常温常压下是一种无色无味或无色无臭而其水溶液略有酸味的气体，也是一种常见的温室气，还是空气的组分之一，主要应用于冷藏易腐败的食品、作致冷剂、制造碳化软饮料和作均相反应的溶剂等。是一种无机物，不可燃，通常也不支持燃烧，低浓度时无毒性。它也是碳酸的酸酐，属于酸性氧化物，具有酸性氧化物的通性，其中碳元素的化合价为+4价，处于碳元素的最高价态，故二氧化碳具有氧化性而无还原性，但氧化性不强。

二氧化碳没有甲醛成分。二氧化碳（carbondioxide），一种碳氧化合物，化学式为CO2，甲醛，化学式HCHO所以，二氧化碳没有甲醛成分。

二氧化碳：Carbon Dioxide ( /ˈkɑːrbən/ /daɪˈɑːksaɪd/ )一氧化碳：carbon monoxide (/ˈkɑːrbən/ /məˈnɑːksaɪd/ )

碳元素和氧元素。二氧化碳的化学式为CO2，二氧化碳是由二氧化碳分子构成的，是由碳元素、氧元素组成的。二氧化碳（英文名称：Carbondioxide），是一种无机物，化学式为CO2，在常温常压下是一种无色、无味的不可燃气体，易溶于水形成碳酸，在自然空气中的体积分数约为0.04%，是空气中的主要组成部分之一。固态的二氧化碳也叫干冰（英文名称：DryIce）是一种形状像冰雪的白色固体。

　　二氧化碳可以跟水反应生成碳酸，CO2+H2O=H2CO3，二氧化碳可以跟澄清石灰水反应,使澄清石灰水变浑浊，CO2+Ca(OH)2=CaCO3(沉淀)+H2O。 　　二氧化碳（carbondioxide）是一种碳氧化合物，是空气中常见的化合物。常压下为无色、无味、不助燃、不可燃。略溶于水中，形成碳酸，碳酸是一种弱酸。二氧化碳一般可由高温煅烧石灰石或由石灰石和稀盐酸反应制得，主要应用于冷藏易腐败的食品（固态）、作致冷剂（液态）、制造碳化软饮料（气态）和作均相反应的溶剂（超临界状态）等。研究表明：低浓度的二氧化碳没有毒性，高浓度的二氧化碳则会使动物中毒。

carbon dioxide是二氧化碳，greenhouse gas是温室气体。温室气体是大气中能吸收地面反射的长波辐射，并重新辐射回地面的气体。它们使地球表面变得像温室一样暖和，由此得名。温室气体包括二氧化碳、水蒸气和甲烷等，因此，二者区别是二氧化碳只是温室气体的一个种类，不能代表所有的温室气体。

所需的二氧化碳可通过混合苏打与柠檬汁制取。希望对你有帮助哈

D 选D。句意：二氧化碳是我们和太阳之间的一道屏障，它使地球上的热量不容易释放出大气层，于是地球就变得越来越暖和。四个名词选项的主要含义：difference“分歧，区别”；comparison“比较”；connection“联系”；barrier“障碍，屏障”。语境说地球的热量因二氧化碳而不容易释放出大气层，因此这里选D，表示“障碍，屏障”。

Carbon dioxide (chemical formula CO2) is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth"s atmosphere in this state. CO2 is a trace gas comprising 0.039% of the atmosphere.Carbon dioxide is used by plants during photosynthesis to make sugars, which may either be consumed in respiration or used as the raw material to produce other organic compounds needed for plant growth and development. It is emitted during respiration by plants, and by all animals, fungi and microorganisms that depend either directly or indirectly on plants for food. It is thus a major component of the carbon cycle. Carbon dioxide is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Amounts of carbon dioxide are emitted from volcanoes and other geothermal processes such as hot springs and geysers and by the dissolution of carbonates in crustal rocks. High levels of CO2 are used to increase plant growth in some tightly closed commercial greenhouses.[1][2][3]As of April 2010[update], carbon dioxide in the Earth"s atmosphere is at a concentration of 391 ppm by volume.[4] Atmospheric concentrations of carbon dioxide fluctuate slightly with the change of the seasons, driven primarily by seasonal plant growth in the Northern Hemisphere. Concentrations of carbon dioxide fall during the northern spring and summer as plants consume the gas, and rise during the northern autumn and winter as plants go dormant, die and decay. Taking all this into account, the concentration of CO2 grew by about 2 ppm in 2009.[5] Carbon dioxide is a greenhouse gas as it transmits visible light but absorbs strongly in the infrared and near-infrared.Before the advent of human-caused release of carbon dioxide to the atmosphere, concentrations tended to increase with increasing global temperatures, acting as a positive feedback for changes induced by other processes such as orbital cycles.[6] There is a seasonal cycle in CO2 concentration associated primarily with the Northern Hemisphere growing season.[7]

你好，我是GROTESQUE1010：(请认真阅读，不要浪费我的写作苦心哦^@@^祝学习顺利）Trees are important because they give us two of life"s essentials, food and oxygen.As we evolved, they provided additional necessities such as shelter, medicine, and tools. In addition, trees are discovered to be satisfied with the needs of our modern lifestyles. For example, our streets, parks, playgrounds and backyards are lined with trees that create a peaceful environment. Therefore, trees are an important part of every community. They are not only increased our quality of life by bringing natural elements, but also provide our wildlife habitats into urban settings. As the matter of fact, we could gather under the cool shade. Furthermore, trees provide during outdoor activities with family and friends. Many neighborhoods are also the home of very old trees that serve as historic landmarks and a great source of town pride.Most importantly, trees contribute to our environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe.

Low-carbon life is the lifestyle of the time to minimize energy consumption,thereby reducing carbon dioxide emissions.Low-carbon life,for those of us ordinary people is an attitude to life.It gives us is a willing and we were creating a low carbon life issues.(低碳生活就是把生活作息时间所耗用的能量要尽量减少,从而减低二氧化碳的排放量.低碳生活,对于我们这些普通人来说是一种生活态度.它给我们提出的是一个愿不愿意和大家共创造低碳生活的问题.)Taomi Shui can be used to wash their hands every day,clean furniture,water the flowers and so on.Clean,naturalmoisture; 2.Scrap paper will pave the lowest in the closet can not only absorb moisture,can absorb the smell in the closet; 4.Drink tea residue,dry it,make a tea pillow comfortable,and helpto improve sleep;(每天的淘米水可以用来洗手、擦家具、浇花等.干净卫生,自然滋润； 2.将废旧报纸铺垫在衣橱的最底层,不仅可以吸潮,还能吸收衣柜中的异味； 4.喝过的茶叶渣,把它晒干,做一个茶叶枕头,既舒适,又能帮助改善睡眠；)Lifestyle to reduce energy consumption when,thereby reducing the carbon,especially carbon dioxide emissions.Low-carbon life,for us ordinarypeople,an attitude,not ability,we should actively promote and to practice the "low carbon" life,pay attention to energy saving,fuel-efficient,water saving,solar terms,starting from scratch.(生活作息时所耗用能量要减少,从而减低碳,特别是二氧化碳的排放.低碳生活,对于我们普通人来说,是一种态度,而不是能力,我们应该积极提倡并去实践"低碳"生活,注意节电、节油、节水、节气,从点滴做起.)

dioxide是二氧化物的意思。dioxide的相关短语有carbon dioxide二氧化碳，Carbon Dioxide无水碳酸，Arsenic dioxide二氧化砷，niobium dioxide二氧化铌，chlorine dioxide二氧化氯（面粉漂白剂，又称Dyox），chromium dioxide二氧化铬，dioxide chlorine二氧化氯。可造句如下：1、The two principal combustion products are water vapor and carbon dioxide.两种主要的燃烧产物是水蒸气和二氧化碳。2、Mars has an insubstantial atmosphere, consisting almost entirely of carbon dioxide.火星的大气层极其稀薄，几乎全部由二氧化碳构成。3、Carbon dioxide is a necessary result of the oxidation of carbon compounds.碳化合物氧化后必然会产生二氧化碳。4、The proposed initiative would mandate a reduction of carbon dioxide of 40%.倡议将强制规定把二氧化碳排放量降低40%。

大气中的恶棍是二氧化碳。二氧化碳似乎并不是一个恶棍。它的毒性不大，而且二氧化碳在大气中的含量如此之少--只有百分之零点零三四--以至于它不会对我们造成伤害。并且空气中的那些少量的二氧化碳对生物有着至关重要的作用。植物吸收二氧化碳并把二氧化碳转化成自身的组织，而植物组织为所有动物（当然也包括人类）提供最基本的食物。在这个过程中，植物还释放氧气，氧气同样是所有动物所必须的。但是，这就是这种看似无害并且至关重要的气体正在对我做的事：它正使海平面逐年慢慢上升。十有八九，海平面会在接下来的一百年里以更快的速度持续上升。

My View on Reducing Carbon Emission 　　Billion tons of carbon dioxide is let off into the air each year, which in part cause global warming and climate changes. Life on this planet will be gravely affected unless we take measures to reduce carbon emission. To achieve this aim, I think the entire society should form the concept of energy-saving and do what we can in our daily life. 　　First, replace the traditional electric bulbs with the energy-saving ones. By saving energy this way, we can reduce a lot of Carbon emission. Second, choose public transportation instead of driving your own car. We can imagine that the fewer cars on the road, the less carbon dioxide will be emitted into the air. Third, when you are shopping, select the goods with simple package. If we select the goods with simple package, we will produce less garbage and thus reduce carbon emission resulting from burning the garbage. And don"t forget to use recyclable bags instead of plastic ones when shopping. 　　Therefore, reducing carbon emission in our daily life is very easy. As long as we all make efforts to do that every day, we can help to reduce billion tons of carbon emission every year. 我认为在减少碳排放 数十亿吨的二氧化碳释放到空气中,这在一定程度上导致全球变暖和气候变化。生活在这个星球上就会受到严重影响,除非我们采取措施来减少碳排放。为了实现这一目标,我认为整个社会应该形成节能的概念和做我们可以在我们的日常生活中。 首先,取代传统的灯泡节能的。通过这种方式节约能源,我们可以减少大量的碳排放。第二,选择公共交通而不是开自己的车。我们可以想象,更少的汽车在路上,更少的二氧化碳会被释放到空气中。第三,当你购物时,选择简单的产品包。如果我们选择简单的产品包,我们将产生更少的垃圾,从而减少燃烧垃圾产生的碳排放。别忘了使用可循环利用的袋子代替塑料袋购物。 因此,在我们的日常生活中减少碳排放是非常容易的。只要我们都努力做,每一天,我们可以帮助减少每年数十亿吨的碳排放。

一般的生物都内含碳元素，所以含碳的物质称为有机物质 (除少量的例外、如二氧化碳及一氧化碳是无机物质。) 碳天然存在三种同位数 (isotope) ，就是 Carbon-12 、Carbon-13 同 Carbon-14 。Carbon-12 是稳定的碳，而 Carbon-14 会 decay 变成 Carbon-12。当生物仲有生命时，生物内含两种碳，而且虽然 Carbon-14 会 decay 变成 Carbon-12，但生物在生时，内含的碳可以同大自然周围的碳互换，所以两种碳的水平是稳定的。 但当生物死后，内含的碳就不会再进行互换，含存的 Carbon-14 就会因 decay 而开始而其 half-life (半衰期) 速度而变少。[一个半衰期内含的碳-14 会减少一半。] 由于 Carbon-14 以半衰期速度而变少，通过量度 (已故的) 生物的 Carbon-14 含量，就可以知道该生物是在那个年代死去的。 一般会以 Carbon-14 监定的物品有生物化石、木制古董家俱、陈年有机制的物品、古尸等。 参考: 自己 (化学学士、现职出土物文修复) The carbon 14 isotope is radioactive. It is present in atmospheric carbon dioxide which is an important material in photosynthesis. After a tree dies it no longer takes in carbon dioxide. The carbon 14 already present in the wood decaying slowly. Scientists can estimate the age of the wood by paring the amount of carbon 14 left in the wood to be amount of carbon 14 in living tress. The age of bones from animals can be estimated in a similar way as animals take in carbon 14 in the food. 参考: my chemistry book carbon-14 dating 放射性碳测定年龄 放射性碳测定年龄给考古学家提供了基本的年代框架。

1.目前低碳生活成为一种流行 2.低碳生活指的是…… 3.作为大学生我应该怎么做 With the advent of the global environmental protection campaign, “low-carbon” has become an increasingly popular expression, a catch phrase, among the environmentally-conscious people. White-collar workers pride themselves on going to offices on bicycles, on foot, or even on roller skates instead of being “the men behind the wheel”. Housewives save water after washing vegetables or clothes for flushing the toilet. Everybody seems to be an environmental activist nowadays. 随着全球性环保运动的出现，“低碳”一词在那些有着环保意识的人们中间，已成为一个日趋流行的语汇，或曰“口头禅”。白领员工们对于骑车上班、步行上班、甚至滑着轮滑上班倍感骄傲，而不必再做那所谓的“呆坐在驾驶舵后面的有车一族”。家庭主妇们也乐此不疲地在洗衣或洗菜之后，将水保存起来，用以冲厕。当下，每个人似乎都成为了环保积极分子。 By “low-carbon lifestyle”, we refer to a pattern of life involving minimum emission of carbon dioxide (CO2), the most important greenhouse gas produced by human activities, primarily through the combustion of fossil fuels. Carbon dioxide is detrimental to human, animal and plant life because it is the primary contributor to global warming that threatens to raise the sea level, leading to the extinction of animals and plants, and ultimately to that of human beings. There is only one Mother Earth for human beings and, literally speaking, preserving the Earth means preserving humanity itself. 所谓“低碳生活方式”， 是指一种仅涉及最低限度二氧化碳排放的生活模式。二氧化碳是人类活动 （主要经由化石燃料的燃烧）所产生的最主要的温室气体。二氧化碳之所以对人类、动物和植物的生命有害，因为它是全球暖化的主要推手，威胁着致使海平面上升，导致动植物灭绝，并最终导致人类本身的灭绝。对于人类而言，只有一个地球母亲，因此，就事论事地讲，保护地球亦即意味着保护人类自身。 The pursuit of a low-carbon lifestyle seems to be a vogue to many people but, in essence, it is a long-term necessity. As college students, there are many ways we can become involved in low-carbon endeavors. We can conserve water, recycle our textbooks, and turn off lights on leaving our classrooms. We can resort to public transportations like buses and subways instead of taxis or private cars. Most importantly, we should reduce the use of computers by rejecting meaningless computer games. Even as students, we have a whole range of channels to pursue a low-carbon lifestyle that is beneficial to ourselves and to humanity as a whole. 追求低碳的生活方式，对许多人而言似乎是种时尚，但本质而言，它却是一项长期的必然。作为大学生，我们有多种多样的方式来投身于低碳事业。我们可以节约用水，循环利用教科书，离开教室时随手关灯。我们在出行时可利用公交车或地铁等公共交通，而放弃出租车或私家车。最重要的是，我们可以通过摒弃那些无聊的电子游戏而减少对电脑的使用。即使作为学生，我们有一系列广泛的渠道，来追求低碳的生活方式，既有益于我们自己，亦有益于全人类。

It not only results jt^omJbejpEomstionfifthejgovemmestjbuLaJsojEises^utjofjthejpeapleu2019s internalheart. 　　Living a low-carbon life is of great importance to every one. First of all, it can protect the environment to a great extent. Second, it can save the limited natural resources and energy, and will leave a better world for our offspring.jThird, it is a healthy lifestyle and will help mould a harmonious social atmosphere. 　　Therefore, how to create a low-carbon life is necessary for us to consider. To begin with, we should save the energy, such as the electricity, water and domestic gas. Second, when we go out we can walk or ride a bike instead of by car. Third, we should not use the plastic bags which are hard to break down. If so, we can live a low-carbon life and gain the happiness of it. 　　过低碳生活英语作文二： 　　Currently,my school is launching an activity whose theme is that actions change the world to advocate the low carbon living. 　　In the activity,we are required to go to school or some other place by bike or by foot as much as possible instead of by bus.And when the Christmas comes,sending e-greeting cards instead of tridional cards of which are made of wood as we know.Besides,we should use both sides of every piece of paper and we should save water as well as electricity. 　　I believe that only we do thus can we have a better living environment. 　　目前，我的学校正在开展一项活动，其主题是行动改变世界，提倡低碳生活。 　　在活动中，要求我们去学校或其他地方的一些骑自行车或步行尽可能而不是乘车。当圣诞来临，发送电子 贺卡 而不是以传统的卡片是用木头做的我们都知道。此外，我们应该利用每一张纸的两面我们应该节约用水用电。 　　我相信只有这样，我们才能有更好的生存环境。 　　过低碳生活英语作文三： 　　Today"s society is a highly developed technological society. However, the shortcomings in the development process are obvious, such as: carbon dioxide, and environmental pollution. But the most serious should be the carbon dioxide problem. 　　Now the problem of global warming because of excess emissions of greenhouse gases. Excessive amount of carbon dioxide emissions, creating a diversified economy and La Nina phenomena lag disorder. Two levels of glaciers melting, polar animals lose their chance of survival at the same time, will lead to rising sea levels, many coastal cities into the water did not result in a few years later. Therefore, we must take the necessary measures to reduce the environmental impact of carbon dioxide.

The concepts of low carbon are low energy and no waste. It is such a significant project that I canu2019t wait to present my ideas on how to promote it. 　　On the first place, a no-car day is supposed to set up every week in our school. Because cars not only cause serious air pollution but also waste energy. On no-car day, neither students nor teachers are allowed to drive to school. Meanwhile, just walk, jump, cycle or run. Use our legs and enjoy the fun. 　　On the second place, we had best not use plastic bags any more. No one can stand the “white pollution”. So, it is wise to use bags which can be reused again and again. 　　Finally, one thing that we should keep in mind: every big thing comes from the subtle. Therefore, as students, we ought to turn out the lights the moment we leave, turn off the tap in time, and reuse our textbook and so on. 　　All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these: no-car day, no plastic bags, and no waste. Letu2019s do it now. 　　过低碳生活英语作文五： 　　Today"s society is a highly developed technological society.

xx，我想告诉你

Calcium carbonate is a chemical pound with the formula CaCO3. It is a mon substance found in rocks in all parts of the world and is the main ponent of shells of marine ani *** s snails coal balls pearls and eggshells. Calcium carbonate is the active ingredient in agricultural lime and is created when Ca ions in hard water react with carbonate ions creating limescale. It is monly used medicinally as a calcium supplement or as an antacid but excessive consumption can be hazardous. Calcium carbonate shares the typical properties of other carbonates. Notably: it reacts with strong acids releasing carbon dioxide: CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) it releases carbon dioxide on heating called a thermal deposition reaction or calcination (to above 840 °C in the case of CaCO3) to form calcium oxide monly called quicklime with reaction enthalpy 178 kJ / mole: CaCO3(s) → CaO(s) + CO2(g) Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. CaCO3 + CO2 + H2O → Ca(HCO3)2 This reaction is important in the erosion of carbonate rocks forming caverns and leads to hard water in many regions. An unusual form of calcium carbonate is ikaite with crystal water CaCO3·6H2O. Ikaite is stable only below 6 °C. 参考: Me Calcium carbonate is a chemical pound with the formula CaCO3.
