<u>Answer:</u> The correct answer is compound.

<u>Explanation:</u>

A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass.

A compound is a substance which is formed by two or more different type of atoms when they chemically combine.

An element is defined as the substance which have only one type of atoms.

Mixture is defined as the solution which is made by the combination of two or more substances in which each substances retain their original chemical properties.

Calcium fluoride is made by the chemical combination of calcium and fluorine atoms. Thus, it is considered as a compound.

Hence, the correct answer is compound.

Describe how the surface area affect the rate of a reaction
leva [86]
When we increase the surface area of an object, more atoms are exposed. Since more atoms are exposed, the atoms can react faster, and this is why the rate of a reaction increases when the surface area increases.

For example, lets say we want to heat a potato. If we just put the whole potato in the microwave, it will take a long time for the potato to get thoroughly heated. However, if we chop the potato into smaller pieces, we will observe that it gets heated much faster. This is because we increased the surface area of the potato, which resulted in more potato atoms to be exposed to the heat, and caused the reaction to be faster.
