fire
Yes, when it is burned (oxidized in air), it releases the chemical energy stored within its chemical bonds.
Coal, gas,oil, and wood. All of these are burned (oxidized in air), which releases the chemical energy stored within its chemical bonds.

Kerosene is a type of chemical potential energy. When kerosene is burned, the chemical bonds are broken which releases energy in the form of heat and light.
there are many cancer causing agents in cigarettes, some we probably haven't found yet. the main carcinogen(cancer causing agent) is acrolein. See the link below for carcinogen compounds in cigarettes smoke.
No, petrol is a form of stored chemical energy. When burned, it releases heat energy which can be used to perform work.
No, there is no CO in tobacco in any form. On combustion there may be CO produced as the conditions usually include a lack of air.
Smoke
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
Yes, it is chemical: look at the remainings of the wick: black carbon-like, not white fiber anymore.
carbon monoxide
When coal is burned, the chemical bonds between carbon and other elements like hydrogen are broken. This releases heat energy due to the combustion process, turning the chemical energy stored in coal into thermal energy. The heat energy can be used to produce electricity or for heating purposes.
