A match burning is a chemical change. Salt dissolving in water is a physical change.
Burning is most likely chemical
Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.
Dissolving is the chemical state in which melting is physical state but the difference is when you dissolve something some things can be brought back but when you melt some thing you are mostly likely not to bring it back to it's natural form
it can be both, but more likely is it a chemical change.

Burning is most likely chemical
Burning is always a chemical change. Look at it like this; if you can't put it back together like it was to begin with, it most likely has gone through a chemical change i.e. copper oxidizing, burning paper...

It is a chemical change anytime you burn something it will most likely be chemical change because something new comes out, for example when you burn the leaves you will get ash which is something the leaves did not have before! your welcome!:)

This is a chemical reaction.
Because Hydrogen and carbon react with O2 This change produces heat, CO2 and H2O (Water Vapor) Burning is an oxidation (reaction with oxygen). The six basic indicators of chemical changes are: TOPIC-B, temperature change, odor change, precipitate, irreversibility, color change, and bubbles of a new gas (or new gas minus a liquid for bubbles to form in). Burning is usually associated with combustion, and would likely be a chemical reaction.
I believe the word you are searching for is Reactivity?
Crushing the graham crackers is a physical change, not chemical. *Chemical reactions and chemical changes are the same thing.
