Fire is a result of a substance being oxidized. Essentially "to burn" means "to add oxygen to." In the case of paper burning, this would be carbon being oxidized producing heat, carbon monoxide, and carbon dioxide. A very similar reaction would be with hydrocarbons such as gasoline. Hydrocarbons are oxidized to CO, CO2 and water. C3H8 + 5O2 --> 3CO2 + 4H20
Heat isn't a substance so it can't have a chemical equation attached to it. There are many chemical reactions that result heat. For the most part it is either a loss of a really small amount of mass or the substance becoming less energetic / more stable.
The equation is Q=m*c*delta t. Q represents heat, usually in calories. m represents the mass of the substance being tested. c represents the specific heat of the substance being tested. delta t represents the change in temperature of the substance (use a calorimeter). Make sure that units are consistant throughout the equation. If Q is represented in calories make sure that the specific heat is cal/g*degrees C instead of Joules/g*degrees C.
The symbol equation for heat is Q = mcΔT, where Q represents the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
Heat=Mass x Specific Heat x Change in Temperature or H=M x Sp. Ht. x ^T
(change in) heat = mass x (final temperature - initial temperature) x specific heat
Q = m x (Tf-Ti) x Cp
Triangle (Or symbol Capital delta) is generally used to represent heat

When writing a chemical reaction for an exothermic process will the heat energy be reactant or product?
Heat will be on the product side of the equation, but it is not a "product" in the same sense as the chemical symbol(s) and/or formula(s) written on this side of the equation, because heat is not a tangible substance but rather an increase in the energy of nearby substances.
