Question

describe an experiment to show reaction between zinc granules and sulphuric acid​

Answer 1

H2SO4 + Zn ---> ZnSO4 + H2

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. We can test its presence by bringing a burning candle near the mouth of the test tube and hearing for a popping sound. Only hydrogen gas burns with a 'pop' sound.

Answer 2

Answer:

zinc displaces hydrogen as it is more reactive (abb tumhe ye sentance ko bada banake likhna padega with prper diagram for scoring good marks) and remember to balance ou the equation mentioning the physical properties
