False. In a chemical change, other forms of energy, such as heat or light, can be changed into chemical energy. This transformation can occur during reactions where energy is either absorbed or released as chemical bonds are broken or formed.

Is carving wax a chemical or physical change?
Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
How is a physical change different than a chemical change?
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes
Is heating a mixture a chemical or physical change?
Heating a wood splint is a chemical change. If this was done in something like a test tube, you will see many things occur that indicate this. First, you will see a werid kind of smoke, the splint turning into black stuff, and a really bad smell. Well the smoke is CO2 and the black stuff is ash from the burning. Because there is a new substance being made and the identity of the original substance(your splint) has changed, the reaction is chemical.

What number cannot be changed in a chemical equation?
You cannot change the subscripts in the molecular identities.For example, H2SO4 must remain H2SO4 and not changed to something like H3SO7.Furthermore, the total mass of the reactants must equal the total mass of the products.
Is baked bread a chemical change?
