Question

When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. CaCO3(s) + 2 HCl(aq) → CaCl2 (aq) + H2O(1) + CO2(8) How many grams of calcium chloride will be produced when 29.0 g of calcium carbonate is combined with 11.0 g of hydrochloric acid? mass of CaCl,: 16.075 g Which reactant is in excess? Caco OHCI How many grams of the excess reactant will remain after the reaction is complete? mass of excess reactant: 14.517

Answer 1

Mass of CaCl₂ produced = 16.7 g

Excess reactant = CaCO₃

Mass of excess reactant left = 13.9 g

Cacos (8) + 2H41 (aq) → CaCl2 + H20 CaCO3(s) + 2HU (aq) → Cau, lep) + H2011) + CQ9) 100 36.5 11 18.0 44.0 Moron mass 19/mon) : Mass of each produced by 29:0g CaCO3 - tlg Cach x 29.04 CaCO3 = 32:199 Cache R 100g CaCO3 Mass of each produced by 110g Hal : 1 1 x 10 H4 = 16-23 1 Ced. 2x 36'5g HU Lesser mass es procluced by Hl. So, Hu is the limiting reactant. Hence, mass of Cack produced = 16.7 g 1004 Reactant en excess = CaCO3) Excess reactant left = 29:09 - ( 102130159 HC * Il 09H4) = 29-09-15.079
