The difference between the energy needed to break bonds, and the energy released when new bonds form, determines the type of reaction. A reaction is: The energy level increases in an endothermic ...

where Q is the heat of combustion. In this reaction, atoms are conserved and the equation balances for each of the species. The reaction is a stoichiometric reaction, and the coefficients multiplying ...

This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate. The reaction produces a lot of heat so the substance shooting out of the bottle is water vapor that is ...
