Question

Nickel powder is used while preparing hydrogen gas in industries. Give reason

Answer 1

Answer:

For industrial purpose, hydrogen gas is prepared by reacting methane with water vapour at very high temperature in the presence of nickel powder, which acts as catalyst in a reaction.

Explanation:

Answer 2

Nickel powder is used while preparing hydrogen gas in industries ,because -

• There are many ways of making the hydrogen gas in the industrial scale.

• But,the cheapest way of hydrogen making is the steam reforming method,where the natural gas is heated to generate huge amount of hydrogen gas.

• In,this steam reforming chemical reaction the nickel powder works as a catalyst which accelerates the formation of the hydrogen gas.
