Make an equation of possible reactions a) Copper + hydrochloric acid b) Sulfuric acid + Barium chloride c) Hydrochloric acid + sodium sulfide d) Sodium + copper sulfate

a.) Cu + 2HCl = CuCl (2) + H (2)
b.) H (2) SO (4) + BaCl (2) = BaSO (4) + 2HCl
c.) 2HCl + Na (2) S = 2NaCl + H (2) S
d) Na (2) + CuSO (4) = Na (2) SO (4) + Cu
