Explanation:

We are given:

A chemical compound has 1 phosphorus atom (P), 3 fluorine atoms (F) and 1 oxygen atom (O).

The chemical formula will contain as many number of atoms, as the given ones.

Thus, the chemical formula for the given chemical compound is

This compound is named as phosphoryl fluoride.

crystallization

Explanation:

When 490g of sugar is dissolved completely in water at a high temperature ( 100°C ) and the solution is been cooled to a lower temperature ( 20°C ), The dissolved sugar in the solution will start to crystallize, This is because the solubility of sugar in water decreases with a decrease in temperature of water.
