Answer:

#H_3C-CH_3(g) + 7/2O_2(g) rarr 2CO_2(g) + 3H_2O(g) +Delta_1#

Explanation:

So two questions: is mass balanced?; is charge balanced? If you like you can double the equation to eliminate the half-integral coefficient; the mass transfer, the stoichiometry is still the same. And what does the symbol #Delta# mean in relation to the reaction?

What about #"methane"#, what about #"propane"#?

Normally, we would present the reactants and products in their standard states under standard conditions......

#H_3C-CH_3(g) + 7/2O_2(g) rarr 2CO_2(g) + 3H_2O(l) +Delta_2#

#Delta_2>Delta_1#...........why?
