Question

A) How many grams of calcium chloride will be produced when 30.0g of calcium carbonate are combined whith 14.0g of hydrochloric acid?

B) Which reactant is in excess and how many grams of this reactant will remain after the reaction is complete?

When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. CaCO3 + 2HCl Arrow CaCl2 + H2O + CO2 A) How many grams of calcium chloride will be produced when 30.0g of calcium carbonate are combined whith 14.0g of hydrochloric acid? B) Which reactant is in excess and how many grams of this reactant will remain after the reaction is complete?

Explanation / Answer

by above equation we get

a)

100 gm of CaC02 reacts with 73 gm of HCL to produce 111 gm of CaCl2

so, 100/73*14 gm of CaC02 reacts with 14 gm of HCL to produce 111/73*14 gm of CaCl2

so,19.17gm of CaC02 reacts with 14 gm of HCL to produce 21.28 gm of CaCl2

b) CaC03 will remain in excess = 30 - 19.17 = 10.83 gm will be left
