What stoichiometric coefficients are used in combustion reactions? How do represent the comproportionation of ammonium nitrate to nitrous oxide?

Answer 1

Usually, the desirable option is the simplest WHOLE number ratio.....

As for myself, often I reject this rule in favour of half-integral coefficients. For example,............the combustion of ethane,

#H_3C-CH_3(g) + 7/2O_2(g) rarr 2CO_2(g) + 3H_2O(l)#,

versus,

#2H_3C-CH_3(g) + 7O_2(g) rarr 4CO_2(g) + 6H_2O(l)#,
both are balanced; I would prefer the former because it is easier to address the stoichiometry, even tho I know that you cannot have a half an oxygen molecule. You can have, however, #"half a mole"# of dioxygen molecules.

For your reaction,

#NH_4NO_3 rarrN_2O + 2H_2O#
which is in fact a #"comproportionation reaction"#, would be the preferred option.
#3NH_4NO_3 rarr3N_2O + 6H_2O# is not the simplest whole number ratio. If I have missed your point I apologize............

Answer 2

The stoichiometric coefficients used in combustion reactions typically involve oxygen gas ((O_2)) as the oxidizing agent. The balanced equation for a combustion reaction usually has the stoichiometric coefficients for the reactants and products determined in such a way that the number of atoms of each element is the same on both sides of the equation.

For the comproportionation of ammonium nitrate to nitrous oxide, it can be represented as:

[ NH_4NO_3 \rightarrow N_2O + 2H_2O ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
