The correct answer is:
B; A new substance forms.
Explanation:
A physical change, such as a state change or dissolving, does not produce a new substance, but an abundant change does. In a chemical reaction, the atoms and molecules that connect with each other are described as reactants. Chemical reactions happen when chemical bonds are broken and formed. If the molecules in a substance crash into each other with enough energy, some of the bonds in the molecules can break. The atoms can make new bonds with different atoms. A new substance forms.
