Answer:
1) when zinc granules are added to the solution of dilute sulphuric acid displacement reaction occurs as zinc is more reactive than hydrogen it displaces hydrogen sulphuric acid.
Zn + H2so4 ------- Znso4 + H2
2)Observations- 1) When dilute sulphuric acid is poured on zinc granules, then zinc sulphate is formed along with the evolution of a gas. Zinc is more reactive than hydrogen, so displaced it from sulphuric acid. 2) The gas evolved is hydrogen
