A: The literal expression of hydrogen combustion is: hydrogen+oxygen = ignition = water, and the reaction type is combination reaction.

Xiaolong said that the experiment of hydrogen combustion can also prove that water is composed of hydrogen and oxygen. Do you agree? Tell me your opinion.

A: I agree. According to the law of conservation of mass, the types of elements remain unchanged before and after the reaction. Hydrogen is composed of hydrogen and oxygen is composed of oxygen. Because the reaction between hydrogen and oxygen only produces water, water is composed of hydrogen and oxygen.
