There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples

See explanation

Explanation:

While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.

Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.

Let us look at three examples;

The carbohydrate in food is composed of carbon, hydrogen and oxygen

The stainless steel materials we use are composed of iron, carbon and other trace elements

Glass is made up of silicon, oxygen and other elements

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
