Would you give five examples of chemical change?
A space shuttle blasting; fireworks exploding; an iron nail rusting; leaves changing color; a campfire burning.
Is the change of identity a physical or chemical property?
If you mean a change in chemical identity, that would be a chemical change.
Sings of reaction in a chemical change?
the three types of elements can be changed, from a solid, to a liquid, to a gas. the temperature can change, it usually gets hotter. the shape can change, from the form it was origanally in then to a gas that expands whatever the substances would be in, it would chage form.
Why would frying an egg be a physical change instead of a chemical change?
Frying an egg is a chemical change.
Is mixing milk and cream to a physical or a chemical change?
It would be a chemical change, because if it was a physical change it would stay the same substance, but in a chemical change you mix 2 different substances to get a new substance.
a.A marshmallow gets black when roasting it in a campfire?
That would be a chemical change.

Is wax melting chemical or physical change?
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Pouring milk in you r oatmeal - Physical or chemical?
It would be physical change because the substance doesn't change. Signs of chemical changes would be absorbing, liberating (releasing) heat, fizzing, changes of color,or giving off light.

Does a candle or a campfire have more energy?
a campfire would have bunches more energy
Is the conversion of two compounds into a solution a chemical change?
Not necessarily. There's something called the enthalpy of mixing which can be responsible for lowering the temperature when two substances are mixed even if no chemical reaction occurs. It may also be an endothermic reaction; if there are other signs of a reaction (formation of a precipitate, evolution of a gas, color change, etc.) then it probably is a chemical reaction.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is flammable a chemical or a physical change?
Something that burns or is flammable would be a chemical change.
