They specify heat flow for the reaction.
Thermochemical equation includes enthalpy ( ΔH ) change in it.
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
The chemical formula (not equation) is KClO3
There are lots of different types of plastics, the ones normally encounterd contain a polymer and additives so they are not pure substances and you cannot write a balanced chemical equation for combustion.
Proteins have a very complicate chemical formula but not a "balanced chemical equation".

A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
A balanced chemical equation.

A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
What information can you determine from the coefficients in this balanced chemical equation? Mg + 2HCl → MgCl2 + H2
A thermochemical equation shows the amount of heat given out or taken in when the reaction occurs. CH4 + 2O2 = CO2 +2H2O, deltaH = -890 kJ/mol Note delta H is negative when heat is given out, exothermic and +ve when endothermic. Sorry can't do delta symbol - its a triangle!
A balanced equation has equal numbers of each type of atom on each side of the equation.The parts of balanced chemical equation are the reactants on the left side and the products on the right side.
