When left over a flame a marshmallow is consumed in a combustion reaction. Assuming a marshmallow is made of entirely sucrose, C12 H22 O11 , and after combustion no residual solid remained, the following chemical equation describes this reaction.
C12 H22 O11 (s) + 12 O2 (g) → 12 CO2 (g) + 11 H2 O(g)
Using the equation above, if the marshmallow contains 6.19 g of sucrose and is the limiting reactant, what is the theoretical of H2 O?
