Concept explainers
(a)
Interpretation:
Whether the percent by mass of each element in a compound depends on the amount of compound is to be explained.
Concept introduction:
The law of mass conservation - Introduced by the famous French chemist Antoine Lavoisier, the law states that there is no change in the total mass of the substances that go into any physical or
The law of definite composition - This law can be defined as; a particular compound maintains an exact universal proportion of elements in its composition, irrespective of the source. The proposal for this law was made by Joseph Proust.
The multiple proportions law - The ratio of the weights of an element with variable mass is small whole numbers when it forms more than one compound by combining with an element with fixed weight.
