Question

2. Identify gas in the following experiment. A. Nitrogen B. Hydrogen C. Oxygen D. Carbon dioxide​

Answer 1

hydrogen c is correct answer

Answer 2

The gas in the given experiment is hydrogen. (option B)

• From the given diagram, we come to know that the said gas is evolved due to the chemical reaction between dilute sulfuric acid and zinc granules.
• Now, zinc sulfate and hydrogen gas are produced, in the chemical reaction of zinc and dilute sulfuric acid. Here, the only evolved gas is hydrogen. So, our said gas should be hydrogen as well.

Zn + H₂SO₄ (dil.) ------> ZnSo₄ + H₂

• Furthermore, in the given diagram, it is also illustrated that the soap bubble containing the evolved gas burns with a pop sound. Here, the indication is again towards the hydrogen gas because hydrogen gas itself burns with a pop sound.
• So, from two different observations, we can finally conclude that the said is gas is hydrogen.
