Question

Complete the word equation:

zinc + hydrochloric acid = __________+hydrogen
copper carbonate + sulfuric acid =_______________+carbon dioxide + water
__________+nitric acid = zinc nitrate+________+water

Answer 1

zinc + hydrochloric acid = zinc chloride + hydrogen

copper carbonate + sulfuric acid = copper sulfate + carbon dioxide + water

zinc + nitric acid = zinc nitrate + hydrogen gas + water

Answer 2

zinc + hydrochloric acid = zinc chloride + hydrogen

copper carbonate + sulfuric acid = copper sulfate + carbon dioxide + water

copper + nitric acid = copper nitrate + nitrogen dioxide + water

Step-by-step explanation:

• Zinc + Hydrochloric acid → Zinc chloride + Hydrogen gas

Zn + 2HCl → ZnCl2 + H2

• Copper carbonate + Sulfuric acid → Copper sulfate + Carbon dioxide + Water

CuCO3 + H2SO4 → CuSO4 + CO2 + H2O

• Copper + Nitric acid → Copper nitrate + Nitrogen dioxide + Water

Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O
