Question

Which of the following is altered during a chemical reaction?

A.The number of atoms
B.The amount of energy conserved
C.The chemical bonds between atoms
D.The types of elements involved in the reation

Answer 1

The answer is D.theypes of elements involved in the reaction

Answer 2

Answer: Option (C) is the chemical reaction.

Step-by-step explanation:

A chemical reaction is defined as the reaction which leads to the formation of a new compound or substance due to exchange of valence electrons of the reactants.

For example,
`2Na + Cl_(2) \rightarrow 2NaCl`

Here, sodium donates its one valence electron to a chlorine atom in order to become stable. Therefore, an ionic bond is formed and a new compound NaCl is formed as a result of this chemical reaction.

Whereas number of atoms and elements involved in a chemical reaction remains the same.

Thus, we can conclude that the chemical bonds between atoms is altered during a chemical reaction.
