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

CaCO_3 + 2HCl to CaCl_2 + H_2O + CO_2 The mass of calcium chloride formed when 2.5 g calcium carbonate are dissolved in excess of hydrochloric acid is

What is the volume of CO_2 liberated (in litres) at 1 atmosphere and 0^@C when 10 g of 100% pure calcium carbonate is treated with excess dilute sulphuric acid ? (Atomic mass Ca = 40, C = 12, O = 16)

How many grams of CO2 can be prepared from 150 grams of calcium carbonate (CaCO3) reacting with an excess of hydrochloric (HCl) acid solution?

What is the volutme of CO_(2) liberted in litres at 1 atmosphere and 0^(@)C when 10% of 100 pure calcium carbonate is treated with excess dilute sulphuric acid? (at mass of Ca=40, C=12, O=16)
