Question

write equation for the reaction of an acid with 1. metal carbonate 2. metal hydrogen carbonate 3. base 4. metallicoxide

Answer 1

1) H2SO4 + CaCO3 --> CaSO4 + H2O + CO2
2) HCl + NaHCO3 --> NaCl + H2O + CO2
3) HCl + NaOH --> NaCl + H2O
4) 2HCl + Na2O--> 2NaCl + H2O

Answer 2

1. Metal Carbonate
acid + metal carbonate= salt + water + carbon dioxide
 Sulphuric acid + zinc carbonate= zinc sulphate + water + carbon dioxide

2.Metal Hydrogen Carbonate
acid+metal hydrogen carbonate= salt+water+carbon dioxide
hydrochloric acid +sodium hydrogen carbonate= sodium chloride+water+carbon dioxide
