A compound differs from an element in that it can be decomposed by a chemical reaction.
A compound, by definition, is made up of two or more elements that have been combined together through a chemical bond.
Thus, the chemical bond or bonds in a compound can be decomposed by a chemical reaction giving rise to the individual elements that make up the compound.
This is unlike an element that can not be decomposed by any chemical reaction.

Answer:
Explanation:
Total mass of substance = 7.22 + 2.53 + 5.25 g
= 15 g
percentage of nickel = 7.22 x 100 / 15
= 48.13
= 48.1 %
percentage of phosphorus = 2.53 x 100 / 15
= 16.87%
= 16.9%
percentage of oxygen = 5.25 x 100 / 15
= 35 %
