It’s often used in combination with the adverb 都 .
Examples
玻璃和水都折光
Both glass and water refract light
bōlí hé shuǐ dōu zhéguāng
If there are more than two homogeneous parts of a sentence, 和 is placed before the last part.
Examples

和 can’t connect parts of a compound sentence, and there is no comma before it.
