Question

write the chemical equation
zinc metal reacts with dilute sulphuric acid to give zinc sulphate solution and hydrogen gas ​

Answer 1

Answer:

Zn + H2SO4 ------------ ZnSO4 + H2

Answer 2

Answer:

Explanation:

Zinc is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.

The products ZnSO4 and H2 (g) are entirely different in chemical composition and chemical properties from the reactants Zn and H2SO4. So, this reaction is a chemical change.
