# What is a balanced chemical equation, including physical state symbols, for the combustion of gaseous ethane into gaseous carbon dioxide and gaseous water?

Jun 10, 2017

${H}_{3} C - C {H}_{3} \left(g\right) + \frac{7}{2} {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} \left(g\right) + 3 {H}_{2} O \left(g\right) + {\Delta}_{1}$

#### 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 $\text{methane}$, what about $\text{propane}$?

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

${H}_{3} C - C {H}_{3} \left(g\right) + \frac{7}{2} {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} \left(g\right) + 3 {H}_{2} O \left(l\right) + {\Delta}_{2}$

${\Delta}_{2} > {\Delta}_{1}$...........why?
