PLEASE ANSWER
Jenny created this drawing to represent what occurred during her Science class experiment. Based on her drawing, how do you know a chemical change has occurred?

A. The atoms on the products side are bonded into different molecules from the atoms on the reactants side.

B. The atoms on the products side are bonded into the same molecules as the atoms on the reactants side.

C. There are the same number of red atoms on both sides.

D. There are the same number of white atoms on both sides.

The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.

Explanation:

The reaction commences when the compounds on the reactant side are ready to react to give the product.  The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.  It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.  In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.
