Question

Write the balanced equation for the following chemical reactions:
(i) Hydrogen + Chlorine ---> Hydrogen chloride
(ii) Barium chloride + Aluminium Sulphate ------> Barium Sulphate + Aluminium chloride
(iii) Sodium + Water -----> Sodium hydroxide + Hydrogen

Answer 1

(i) H₂(g) + Cl₂(g) ------> 2HCl(g)
(ii) 3BaCI₂(aq) + Al₂(SO₄)₃(aq) -----> 3BaSO₄(s) + 2AlCl₃(aq)
(iii) 2Na(s) + 2H₂O(l)------> 2NaOH(aq) + H₂(g)
