Concept explainers
(a)
Interpretation:
Water is a mixture or pure substance has to be identified and explained.
Concept introduction:
Mixture:
A mixture always contains two or more substances that can be present in varying amounts. The components of a mixture do not lose their identities and may be separated by physical means. There are two types of mixture,
- Homogeneous mixture
- Heterogeneous mixture
Homogeneous mixture:
Homogenous mixture consist of a single phase be it liquid, gas, or solid the chemical composition is the same for any sample of the mixture.
Heterogeneous mixture:
Heterogeneous mixture consist of different phase are not uniform they will not have an identical composition
Pure substance:
A pure substance (element or compound) always has a definite composition by mass. The elements in the compounds lose their identities and may be separated only by chemical means.
