Question

Which of the following happens during a chemical reaction?

a. Atoms of reactants are destroyed.
b. New atoms are created to form the products.
c. Atoms of reactants rearrange to form new substances.
d. The total mass of reactants is less than the total mass of products.

I think it's a but I'm not sure.

Answer 1

c. atoms of reactants rearrange to form new substances

Answer 2

Answer: Option (c) is the correct answer.

Step-by-step explanation:

A chemical reaction is defined as the reaction that leads to formation of new substances through exchange of electrons.

For example,
`2Al + 3CuCl_(2) \rightarrow 2AlCl_(3) + 3Cu`

Here, aluminium on displacing copper from copper chloride leads to the formation of a new compound, that is, aluminium chloride.

Hence, it shows that atoms of reactant molecules rearrange themselves to form new substances.

Thus, we can conclude that during a chemical reaction atoms of reactants rearrange to form new substances .
