In exothermic reactions heat is liberated.
So reaction can be
reactants---->products+heat
An exothermic reaction is a reaction that releases heat. An example of this is the burning of methane, CH4 + 2 O2 --> CO2 + 2 H2O.
reactant -> product + energy
Heat is written as a product of the reaction (apecs answer)
Hf, reactants > Hf, products
Heat is included as one of the products.
If the reaction is exothermic, this means heat is released and would thus appear as a PRODUCT, i.e. it would appear on the right side of the equation. This would be written as A + B ==> C + D + heat
It is exothermic. Heat will be released to the environment in this reaction. It is also a single replacement reaction. Here is the equation: 2HCl + Mg --> MgCl2 + H2

Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.

When aluminum burns, the reaction is highly exothermic.

... is an exothermic reaction (opposite of 'endothermic')
It is called an exothermic reaction. Example: a burning candle
