Question
How is a compound different from a mixture?AMixtures are created through physical changes; compounds are created through chemical reactions.BCompounds are created through physical changes; mixtures are created through chemical reactions.CMixtures, on average, are heavier than compounds.DCompounds, on average, are heavier than mixtures.
Solution
The correct answer is A. Mixtures are created through physical changes; compounds are created through chemical reactions.
Here's why:
-
Mixtures: A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically. In a mixture, the substances keep their original properties. For example, if you mix sand and water, you can still separate the sand from the water, and they both retain their original properties. The creation of a mixture involves a physical change, not a chemical reaction.
-
Compounds: A compound is a substance
