When left over a flame a marshmallow is consumed in a combustion reaction. Assuming a marshmallow is made of entirely sucrose, C12H22O11, and after combustion no residual solid remained, the following chemical equation describes this reaction. C12H22O11(s) + 12 O2(g) → 12 CO2(g) + 11 H2O(g) Using the chemical equation above, if a third marshmallow was combusted and the actual yield of H2O was 5.404 g and the theoretical yield was H2O was 8.483 g, what is the percent yield of the reaction?
