General Chemistry 2 - Balancing chemical equations - 3

Write the balanced chemical equations of the following reactions:

  • when an aqueous solution of potassium chlorate is heated, it decomposes to form potassium chloride and oxygen gas.
  • when calcium hydroxide reacts with hydrochloric acid, calcium chloride and water are produced.
  • 2 KClO3 (aq) → 2 KCl (aq) + 3 O2 (g)
  • Ca(OH)2 (aq) + 2 HCl (aq) → CaCl2 (aq) + 2 H2O (l)
