calcium carbonate is a kind of carbon dioxide?

急问~~如何做这到化学题?
Phosphorus can be prepared from calcium phosphate by the following reaction.
2 Ca3(PO4)2(s) + 6 SiO2(s) + 10 C(s) → 6 CaSiO3(s) + P4(s) + 10 CO(g)
Phosphorite is a mineral that contains Ca3(PO4)2 plus other non-phosphorus-containing compounds. What is the maximum amount of P4 that can be produced from 3.7 kg of phosphorite if the phosphorite sample is 70.% Ca3(PO4)2 by mass? Assume an excess of the other reactants

1).Write a balanced equation for the reaction of calcium phosphide,Ca3P2,with
water,H2O,forming calcium hydroxide,Ca(OH)2 and phosphine,PH3.Calculate the
heat of reaction from the standard heats of formation listed below.Then,
calculate the standard enthalpy change when 39.4 grams of calcium phosphide is
consumed in this reaction.standard heat of formation(Ca3P2) -504 kJ/mol
standard heat of formation(H2O) -285 kJ/mol standard heat of formation(Ca(OH)2)
-986 kJ/mol standard heat of formation(PH3) 5 kJ/mol
2).If 2.765×10-2 mol of NH3 gas has a volume of 715 mL at
42°C,what would be the volume of 2.765×10-2 mol of N2 gas
under identical temperature and pressure conditions?
3).A sample of
N2H6CO2 weighing 14.5 grams is heated to
80oC in a 1.0 L container.All of the salt sublimes into
NH3(g) and CO2(g) according to the following equilibrium
process.
N2H6CO2 (s) ↔ CO2 (g) + 2NH3 (g)
Determine the partial
pressure of the NH3(g) in the system in atmospheres.

Carbohydrates,fiber,vitamin,calcium and iron in foods
Here are five groups of foods.They are all very important for our health.We shouldn’t like to eat one group of food and dislike another group.
*Grain group
Grain group foods give us carbohydrates.With the help of carbohydrates,we are able to play,learn,sleep and keep our bodies running 24 hours a day!
Grain group foods come from many different grains like rice and wheat.Grain group foods also give us other things help keep us healthy.
*Vegetable group
Foods in the vegetable group give us vitamin A that helps us see in the dark.Vitamin A also helps keep or skin healthy.Vegetables also give us vitamin C,which helps make cuts healthy again and fight infections.
*Milk group
Milk group foods give us calcium that helps build strong bones and teeth.They also give us other important substances,including protein,vitamin A,vitamin D and vitamin B.
*Meat group
Meat group foods help build strong muscles.Foods in this group give us protein and iron.Iron is important because it carries oxygen to all parts of your body,and helps your body make energy to get you through busy days.
*Fruit group
Fruit group foods give us vitamin C,vitamin A and fiber.
Please remember:Eat right then you will be healthy.

求教ca离子泵的问题
钙泵(calciumpump) 亦称为Ca2+-ATP酶,它催化质膜内侧的ATP水解,释放出能量,驱动细胞内的钙离子泵出细胞.由于其活性依赖于ATP与Mg2+的结合,所以又称为(Ca2+,Mg2+)-ATP酶.
那Mg离子就沉积下来了么
