Detailed explanation-3: -Water is a homogeneous mixture. When you look at a homogeneous mixture, you can’t see the substances that make up the mixture; everything looks the same. You can’t see the hydrogen and oxygen separately in the water. This makes it a homogeneous mixture.

Detailed explanation-5: -H2O contains hydrogen and oxygen but it is a pure substance.
