Which of the following terms describes cinnamon sugar?
1. element
2. mixture
3. pure substance
4. compound

Option (2) is the correct answer.

Explanation:

An element is defined as a substance that cannot be broken down into simpler substances.

For example, magnesium is a metal and it contains only atoms of magnesium.

Whereas a compound is defined as a substance that contains two different elements which are chemically combined together in a fixed ratio by mass.

For example, KCl is a compound in which atoms are present in 1:1 ratio.

Both an element and a compound are pure substances.

A mixture is defined as a substance in which two or more number of different substances are mixed together. Particles of a mixture never combine chemically to each other.

For example, cinnamon sugar is a mixture of different essential oils and spices.

Thus, we can conclude that the term mixture is the term which describes cinnamon sugar.

it means there are 3 atoms of oxygen
