Question
The Hydrogen gas was first prepared by:
- Robert Boyle
- Henry Cavendish
- Antoine Lavoisier
- Niels Bohr
Hint:
He was an English natural philosopher and scientist did important experiments and was a theoretical chemist and physicist.
The correct answer is: Henry Cavendish
The correct option is b)Henry Cavendish.
- Henry Cavendish was the first to prepare and understand the properties of hydrogen. He made this by adding acid to a metal fillings.
- Gas had previously been made by Robert Boyle (1627–1691), but he confused it with ordinary air. Cavendish also dealt with carbon dioxide, or something called "solid air".
- In 1766, Cavendish addressed the prominent question of the day that water and oxygen were the only basic elements.
- During his experiments, he isolated hydrogen and identified it as a peculiar element.

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.
