Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
It should be an endothermic reaction requiring heat energy to return to the products to their higher energy reactants.
It a chemical reaction produces heat and light then reversing the reaction should
Combustion
Any chemical will give off light if it is heated to a sufficiently high temperature. There are also chemicals that give off light at relatively low temperatures. Fireflys produce a type of chemical called luciferins, that produce light.

2Na + 2H2O = 2NaOH + H2
An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation:reactants → products + energy

Yes, but its more of the result of the reaction, which is heat and light. More efficient is florescent which produce more light than heat.
can heat add energy to the chemical reaction in a glwo stick
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
Only if you include heat (magma, meteors, light bulbs), charged particles (lightning, aurora) and electroluminescence (LED) under "chemistry". None of these produce light by what we normally think of as a chemical reaction.

Chemical reactions that produce heat (or energy) are known as Exothermic Reactions. (Example: combustion of fuels)
Heat (but no chemical reaction): this is enthalphy of solution.
