Answers
Answer:
ans. D
Explanation:
hydrogen will be liberated upon reaction of acid and metal
Answer:
Option [d] is the correct option.
Explanation:
Unpure hydrogen gas burns with a popping sound. The great combustibility of hydrogen is the cause. Impure hydrogen is defined as laboratory-prepared gas that has not been purified. The contaminants, such as traces of oxygen, nitrogen, and water vapour, are present. A highly exothermic reaction can place when impure H2 gas is exposed to a spark. As a result, there is a quick increase in temperature, which causes the gases to expand when heated. In milliseconds, this growth takes place incredibly quickly. This quick expansion of these heated gases causes a compression on the surrounding gases, creating a sound wave that humans perceive as a pop sound. Even if hydrogen is completely pure, diffusion causes it to lose its purity when exposed to air. There won't be any pop sound if you add very small amounts of pure H2 because there isn't enough of the gas to cause rapid gas expansion.
