Which of the following statements is true? the atmosphere is an example of a solution. in a glass of sugar water, sugar is the solvent. the individual substances in a mixture lose their original chemical properties. all of the above.

The individual substances in a mixture lose their original chemical properties

Explanation:

A solution is formed by solutes and solvent. The solvent is the compound that is capable of dissolving the other compounds. A mixture occurs when two or more compounds are together without react.

So, the atmosphere is a mixture of gases, not a solution.

In a glass of sugar water, the sugar is the solute and the water is the solvent because the sugar is the compound which is dissolved.

In a mixture, the individual substances contribute to the chemical properties of the mixture, but they now will be different. For example, the air is less reactive than oxygen pure, because the air is a mixture of gases. So, the individual substances lose their original chemical properties.

it should be p1 v1 = p2 v2
