Write a balanced chemical equation for each word equation below:

  1. Magnesium Bromide (aq) + Chlorine (g) ------> Magnesium Chloride (aq) + Bromine (l)
  2. Sodium (s) + Water (l) ------> Sodium Hydroxide (aq) + hydrogen (g)
  3. Potassium Nitrate (s) ------> Potassium Nitrite (s) + Oxygen (g)
  4. Zinc (s) + Hydrochloric Acid (aq) -------> Zinc Chloride (aq) + Hydrogen (g)
  5. Calcium Oxide (s) + Hydrochloric Acid (aq) ------> Calcium Chloride (aq) + Water (l) Balance the following chemical equations, then convert them to word equations:
  6. Mg(s) + O2(g) ----------> MgO(s)
  7. Fe(s) + O2(g) -----> Fe 2 O3(s)
  8. H 2 O(l) + N 2 O3(g) -----> HNO2(aq)
