What are the key differences between solutions and mechanical mixtures? Give two examples of each. -Science

A mixture is two or more substances combined. There are no chemical reactions involved, so no new substances are made. Mixtures can often be separated by physical means. For example, a mixture of sand and water could be separated by filtration. A mixture of sand and iron filings could be separated magnetically.

A solution is one kind of mixture. It’s commonly the combination of a liquid and a solid, so that the particles of the solid mix with those of the liquid so that they can’t be separated by filtration. However solutions may be separated in other ways. For example, in salt water the salt and the water can be separated by distillation.

Explanation:

answer: a chemical reaction

explanation:

im not wrong

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
