The total number of protons in 10g of calcium carbonate is (N_(0) = 6.023xx10^(23))

The total number of protons in 10 g of calcium carbonate is (N_(0) = 6.023 xx 10^(23)) :-

The atomic mass of calcium (Ca) is 40 g. The number of moles in 60 g of calcium are

The mass of CO, obtained when 60 g of calcium carbonate is treated with excess of hydrochloric acid is:

Write two uses of calcium carbonate.

Calcium carbonate decomposes, on heating , to form calcium oxide and carbon dioxide. When 10 g of calcium carbonate is decomposed completely, then 5.6 g of calcium of oxide is formed. Calculate the mass of carbon dioxide formed. Which law of chemical combination will you use in solving this problem ?

If the law of constant compositon is true, what weights of calcium carbon, and oxygen are present in 1.5 g of calcium carbonate, if a sample of calcium carbonate from another source contains the following percentage composition: Ca = 40.0%, C = 12.0% , and O = 48.0% ?
