(d) combination of any two or more elements or compounds

Answer 1

Answer:

combination of any two or more elements or compounds

Answer 2

Answer:

(d) combination of any two or more elements or compounds

Explanation:

A chemical reaction involves a combination of any two or more elements or compounds to give one or more new product.

The chemical reaction does not involve the only a combination of two atoms, it does not take place only among the same type of elements either nor only among the same type of compounds.

It is true that it can take place among the same type of atoms, compound, and elements but it is not true that it will take place only among the same type of atoms, elements or compounds.
