Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ... When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.
Answer:
It's explained below.
Explanation:
An everyday situation is when we raise an object.
Now, when we raise an object, energy is transferred to the Earth object system and thus the gravitational field energy of the system will increase.
Now, this energy is usually released when the object falls. The mechanism of this release is known as gravitational force.
In the same manner, two magnetic and electrically charged objects that are interacting at a distance will exert forces on each other and this can lead to transfer of energy between the interacting objects.
From,
RAM=element×its relative abudance/total abudance
=((107×13)+(12×109))/25
The answer is=107.96
