The new and different substances formed as a result of a chemical change (reaction) are the products of the reaction.
Exploding fireworks is the result of chemical reactions.
Fuel. :)
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.

This is a little tricky. Striking a match is a physical act, but it does induce chemical changes. It depends on exactly what you mean by "lighting", ultimately. The end result is definitely a chemical change.

Nope. (Well, the chemical reaction of the high explosives in an A- or H-bomb warhead result in high pressure that then results in a nuclear change (BOOM), but that's a side-effect, not a direct result of the chemical change.)
