How do substances change after chemical reaction? a. they change phase b. their atoms are rearranged c. their atoms lose electrons d. they lose mass

B.their atoms are rearranged

Explanation:

All the chemical reactions follow the rule of conservation of matter. This rule states that matter can neither be created nor be destroyed during a chemical reaction. The number and type of atoms on the left hand side of a chemical reaction will be same on the right hand side of that chemical reaction. The atoms of chemical species/substances on the left hand side represent reactants while on the right hand side represent products. The only difference is that these atoms get rearranged when the products are formed.
