Answer 2

Answer: The above experiment shows reaction between metal and metal oxide and hydrogen gas is liberated  during the process.

Explaination: The above experiment shows following reaction,

Zn(s) + dil. H₂SO₄ → ZnSO₄(s) +H₂(g)

• Here, we can see that zinc metal is reacted with dilute sulphuric acid to form zinc sulphate ,which is also known as zinc salt, and there's a liberation of hydrogen gas.

• The detection of this hydrogen gas is identified, when a burning candle is brought near the test tube it, produces a pop sound.
• Liberated hydrogen gas is used in the hydrogenation of oil.

Hydrogenation reaction

• Hydrogen and another element like nitrogen undergo a chemical reaction known as hydrogenation, where ammonia is formed.
• The reaction occurs in the presence of a catalyst such as nickel, palladium, or platinum. The method is frequently used to saturate or decrease organic molecules.
