copper (II) sulfate pentahydrate能溶于水吗?

帮忙修改语法.thx thx
Throughout this chemical analysis of Copper Sulfate lab,the concept was to identify the moles and balancing the equation to represent the reaction of this measurement.During the lab,we also determined the mass of the products and reactants,they produced new molecules and reacted new physical changes.This lab was divided into two parts which were finishing all the steps and waiting the result until the day after the experiment.The purpose of this lab was to determine the number of moles of iron consumed and the number of moles of copper produced in the reaction of iron with aqueous copper (II) sulfate.The mole is a suitable component for investigating chemical reactions which is equal to 6.002 x 10^23 particles or also can be called Avogadro’s number.
During this intergraded lab,the procedure was complex.First,we weighed out the Copper Sulfate and measured out the distilled water then mixed them together as a chemical compound in the beakers.Then we weighed out the iron nail and recorded the mass of each item.After that,we putted the beaker on the hot plate and heat it until the Copper sulfate started melting and dissolved the crystals.It started turning into blue liquid,and added the nail on.During the process,the substance (iron nail) was shaken and bubbled,it was look like the pressure of the oxygen started mixing with the water which absolutely manifested a chemical and physical reactions.The last step of this experiment was poured the liquid through the filter paper and waited until blue liquid wept down to that big beaker then folded the filter paper and wait until the second day.The day after was only to weigh out the filter paper again because we wanted to validate the law of conservation of mass,if the mass changed which means it does not follow the law,and if it has a zero change in mass which means the law was accepted in the experiment.

求教句子结构：The actual figure was made of copper supported by a metal framework 。。。。。。
这是新概念二93课的一句（曾在这里问过，但咂摸一番还是有点不解）：
The actual figure was made of copper supported by a metal framework which had been especially constructed by Eiffel. （这座雕像的主体是用铜制成的，由艾菲尔特制的金属框架支撑着）
为了好问，先把我没有疑问的从句简化掉，剩下：
The actual figure was made of copper supported by a metal framework
在我的理解中，actual figure后面省略了that，后面的was made of copper是定语从句（是叫定语从句吧？），便成了这样：
The actual figure (that was made of copper) supported by a metal framework
句子的主干就剩下“雕塑的主体被金属框架支撑着”，于是我的疑惑就来了：这里看起来是个被动语态，但是supported前面为什么没有be动词呢？
有劳高人点拨开窍，感激涕零！

急求纯手工翻译!谢谢各位!
一introduction
precipitation of copper sulfides from moderate-temperature, moderate- to high-salinity, oxidized fluids at oxidationreduction interfaces has been common since the paleoproterozoic. the largest known deposits occur within sedimentary basins, generally at the contact between subaerial red-bed sequences and overlying marine or lacustrine shales, siltstones, sandstones, or carbonate rocks. deposits in such settings have been termed sediment-hosted stratiform copper deposits (kirkham, ***) or sedimentary rock-hosted stratiform copper deposits (cathles and adams, 2005).
sedimentary rock-hosted stratiform copper deposits consist of relatively thin (generally <30 m and commonly <3 m) sulfide-bearing zones that are peneconcordant with lithologic layering. the deposits occur in a variety of sedimentary rock types with a variety of reductants. the configuration of the mineralized zone ranges from sheetlike, with extensive horizontal dimensions, to tabular or roll-front geometries, with limited horizontal dimensions (kirkham, ***).
二basin architecture of the sedimentary rock-hosted stratiform copper deposits
sedimentary rock-hosted stratiform copper deposits are the products of evolving basin-scale, or at least sub-basin-scale, fluid flow systems. similar to all ore systems, these deposits can be thought of as the end products of processes involving a source(s) of metal and sulfur, a source(s) of metal-transporting fluid, transport paths, possible mobile reductants, a thermal or hydraulic pump, and the chemical and physical factors that result in precipitation (“trapping”) of the sulfides. whereas the general nature of the ore fluids responsible for the formation of these deposits is clear (rose, 1976; brown, 1992), exact fluid compositions in terms of metal and sulfur contents are not known due to a lack of fluid inclusion data (hitzman et al., 2005). this lack of data is the result of the absence of suitable coarse minerals, containing workable fluid inclusions, intergrown with sulfides in the vast majority of deposits.
三critical factors for the formation of sediment-hosted stratiform copper deposits
sediment-hosted stratiform copper deposits require oxidized metal source beds (red beds), reduced facies to serve as metal traps, and saline brines capable of leaching and carrying metals. to form significant deposits, mineralizing fluids must be confined within the red beds and expelled through relatively focused zones, often in areas of stratal pinch out or linear structural zones. potentially productive host rock sequences and geometric configurations are commonly found in rift basins.

修改句子s语法,
During the experiment,the copper was totally burned black and the sulfur became yellow steam,because of the hot temperature,it produced water and vapor.The result of this experiment was the weight before heating is greater than after heating due to the oxygen pressure and the broken molecules lost weights.
To clarify the above data,it showed the chemical changes between the initials and the consequences of mass after heating it.
The reactants above showed us the chemical and physical changes during the experiment.
The above class data demonstrated the total reactant,the total product,and the change of mass of each group.Some changes were extremely small which Group 16 was.Each of them had different chemical reactions because of their molecule structures.A great job for this lab was to remain small changes by doing each step correctly.
In case Group 16,the greatest result of this synthesis,the change of mass did not increase a lot which meant they preserved the law of conservation of mass using copper and sulfur.In case Group 1,the change of mass increased four time of Group 16 so the gap was great big difference.
t is to identify potential sources of error in the experiment.My average of mass was 2.53g and the percentage of error was 10.90%.The average (change in mass) for the class was 0.57g and the source of error was 1.99%.The answers might not be accurate because there was not exact answer for quantitative chemical,and we just want to know the approximate figures.
