The force of the exhaust gases firing backward is like the blast coming out from a rocket engine and creates an equal and opposite "reaction" force that sends the firework shooting forward up into the air. Basically, this is a fuel within a container that forces combustion to release energy in one direction so the firework goes up.

When you add some heat, you provide enough activation energy (the energy that kick-starts a chemical reaction) to make solid chemical compounds packed inside the firework combust (burn) with oxygen in the air and convert themselves into other chemicals, releasing smoke and exhaust gases such as carbon dioxide, carbon monoxide, and nitrogen in the process.
