Question

what volume co2 is produced when 200g of caco3 reacts with excess hcl

Answer 1

Answer:

ou need to start off by writing out a balanced chemical equation which will show you the relationship between CaCO3 and CO2:

CaCO3 + 2HCl → CaCl2 + CO2 + H2O

This equation tells you that for every mol of CaCO3 consumed you will be producing 1 mol of CO2. In other words there is a 1:1 relationship between CaCO3 and CO2.

The next step is to determine the amount of CaCO3 you have in moles, and since HCl is in excess, you do not need to worry about which one is the limiting r
