<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another.

In a chemical reaction, total mass on the reactant side is equal to the total mass on the product side.

It can also be stated that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on product side.

For Example: Formation of water from hydrogen and oxygen gas.

2H_2+O_2\rightarrow 2H_2O

On reactant side:

Number of Hydrogen atoms = 4

Number of Oxygen atoms = 2

On product side:

Number of Hydrogen atoms = 4

Number of Oxygen atoms = 2

Hence, the correct answer is Option D.

What happens in the artificial transmutation of an element? Include an example.
Mice21 [21]
What happens in the artificial transmutation is that the nucleous is bombarded with high energy particles which we can describe as kinetic energy and the idea for them is to induce what we call transmutation. Also what happens is that the high energy particles are accelerated. One of the examples is when nitrogen is transformed into hydrogen by combining its nucleous with an alpha particle
