The chemical equation below shows that hydrogen and oxygen chemically react to form water. Which of these is true?

A.

Water is a pure substance and has the same properties as oxygen.

B.

Water is a pure substance and has the same properties as hydrogen.

C.

Hydrogen and oxygen are pure substances that have identical properties to each other.

D.

Hydrogen, oxygen, and water are pure substances that each have different properties.

D

Explanation:

Hydrogen, oxygen, and water are pure substances that each have different properties.

Although the 3 of them are pure substances, but they nonetheless have different properties. These properties could either be their physical properties, or their chemical properties. This is particularly so because since Oxygen and Hydrogen the major components in water have different properties, it is only right if their product, water, has different properties also.
