Which is a chemical property of hydrogen?
a) it is a light gas.
b) it is a combustible gas.
c) it is a colorless gas.
d) it has a boiling point of -252.87°c.
e) it is a good conductor of electricity.

The correct answer is option B) It is a combustible gas.

Explanation:

Hello!

Let's solve this!

The chemical properties affect the structures of the molecules and the physical properties do not affect it.

Among the physical properties of hydrogen, we find that it is a colorless gas, the boiling point and that it is a light gas.

Among the chemical properties proposed here, the option is that it is a combustible gas. Since after combustion the gas lost its original structure.

Then, we will conclude that the correct answer is option B) It is a combustible gas.

the answer is the first option
