Answer:
Explanation:
When dilute sulphric acid reacts with zinc granules, then zinc sulphate and hydrogen gas are formed. Zinc being more reactive than hydrogen, displaces it from sulphuric acid. This liberated hydrogen is evolved as hydrogen gas. When zinc reacts with dilute sulphuric acid hydrogen gas is evolved, with an effervescence.
When dilute hydrochloric acid is added to granulated zinc placed in a test tube, a colourless and odourless gas is evolved with bubbles.
The chemical reaction can be written as:
Zn + 2HCl → ZnCl
2 + H 2
