Write the word equations below as chemical equations and balance:

copper + sulfuric acid yield copper (II) sulfate + water + sulfur dioxide

Cu +2 H₂SO₄ = CuSO₄ +2H₂O +SO₂.

Copper is a metal which is sitting just below the hydrogen in the reactivity series.

When metallic copper is put in dilute sulphuric acid and the solution is heated, the solution forms a bluish gdiscoloration with evolution of a gas with smell of brunt sulphur.

Its a redox reaction as the metallic copper gets oxidized to cupric ions and the sulphuric acid gets reduced to Sulphur dioxide gas.
