Smog usually is produced through a complex set of photochemical reactions involving volatile organic compounds (VOC's) and nitrogen oxides in the presence of sunlight that result in the production of ozone.
Combustion Reactions. A combustion reaction is when a substance reacts with oxygen and releases a huge amount of energy in the form of light and heat. A combustion reaction always has oxygen as one reactant. The second reactant is always a hydrocarbon, which is a compound made up of carbon and hydrogen. A combustion reaction also always produces CO2 and H2O. Balancing Combustion Reactions. Balancing combustion reactions is easy. First, balance the carbon and hydrogen atoms on both sides of the equation.
