Question

Which of the following represents a compound? C20 H2O O2 H2

Answer 1

the answer is C2O.............

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

A compound is defined as a substance that has two or more number of different atoms which are chemically combined to each other in a fixed ratio by mass.

For example,
`H_(2)O` contains two atoms of hydrogen and one atom of oxygen which are chemically combined together in 2:1 ratio. Therefore, it is a compound.

On the other hand, if a substance contains only atoms of one type of element then it is known as a molecule.

For example,
`C_(2)`,
`H_(2)`, and
`O_(2)` are all molecules.

Thus, we can conclude that out of the given options
`H_(2)O` represents a compound.
