43.7 L of butane (C4H10) measured at S.T.P is burned in excess oxygen. Write an equation for the reaction and what is the volume of carbon dioxide measured at S.T.P?
1 Answer
We get approx.
Explanation:
The normal rigmarole is to balance the carbons as carbon dioxide, the hydrogens as water, and then balance the oxygens on the reactant side. If you like you can double the entire reaction to give integral coefficients, i.e.
I usually prefer the FORMER representation in that the stoichiometry is EASIER to rationalize. And of course while we cannot have half an oxygen molecule, CERTAINLY we can have a
And given
I have assumed that the molar volume of an Ideal Gas is
