Question
The metal that acts as a catalyst in the laboratory preparation of Hydrogen is:
- Zinc
- Copper
- Iron
- Calcium
Hint:
It has atomic number 29.
The correct answer is: Copper
The correct option is b)copper
Granular zinc is ideal for making hydrogen gas in chemical laboratories. This is because it usually contains small amounts of copper, which acts as a catalyst for the chemical reactions involved, allowing it to speed up chemical reactions without actually participating. .

Read the following paragraph carefully.
X is prepared when the wood is heated in a limited air supply. This X is used to increase the absorption capacity of gases by heating them at a very high temperature. The substance obtained by this process is called Y. When this X reacts with the oxide of the metal, it gives the mixture of Z and W. This mixture is also called producer gas.
Identify the compounds X, Y, and Z in the above paragraph.
