Answer:
The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance
Explanation:
To determine the average atomic mass, we require abundance of every isotope in the nature.
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Answer:

Explanation:
im guessing because there is no diagram
Answer:
The right answer is (D)
Explanation:
If captured, some of the energy of the excited electrons is used to split carbon dioxide into carbon and oxygen.
Electron when in excited state either it jumps to the higher orbital if it has absorbed energy or it can fall to a lower orbital.
Answer:
Conservation of Mass
Explanation:
Conservation of Mass -
According to the works of Antoine Lavoisier , he stated that , mass is always conserved in a chemical reaction .
For example ,
carbon reacts with oxygen , it forms carbon dioxide ,
But , by using the principle of conservation of mass ,
mass can not created or be destroyed , hence , the mass of the initial state and final remains constant , there is only the transfer of mass or matter .
