What is a limiting reactant problem?
Well, usually all combustion reactions are such...
CLEARLY, methane, the hydrocarbon, is in stoichiometric deficiency, and dioxygen is the reagent in EXCESS... So how much carbon dioxide is produced from the given reaction? Take that atmosphere...!
Note that sometimes, especially for long-chain hydrocarbons, such as diesels, INCOMPLETE combustion can occur to give carbon and carbon monoxide as the products of incomplete combustion. We could represent this by saying that SOME
Is this balanced? Clearly, we would have to interrogate the combustion products in order to represent the reaction....
