(ii) Sodium hydroxide and sulfuric acid interact simultaneously and make sodium sulphate and water. (iii) Calcium carbonate and water are formed when reacting between calcium hydroxide and carbon dioxide.​

Answer 1

. kClO3 = KCl+O3

.NaoH+H2SO4 = Na2SO4+H2O

i) H2 + Cl2 → 2HCl

ii) 3BaCl2 + Al2(SO4)3 → 2AlCl3 + 3BaSO4

iii) 2Na + 2H2O → 2NaOH + H2
