Question

The unknown compound (molecular formula from #1) reacts with oxygen in a combustion reaction
to form water and carbon dioxide. 
a. Write a balanced equation for this reaction. 
b. If 20.2 grams of the unknown compound reacts with 25. mL of oxygen at 760 torr and 273.15 K, then which reactant is limiting? 
c. Calculate the theoretical yield of carbon dioxide in this reaction in grams. 
d. All combustion reactions are redox reactions. Label which element was oxidized and which element was reduced as well as the agents (which reactant was the reducing agent and which reactant was the oxidizing agent) in this reaction. 
e. Given the following standard molar enthalpies of formation for the reactants and products,calculate the DH°reaction in kJ/mol. 
Reactants and Products in the Reaction DH°f (in kJ/mol)
C2H4O2 (l) -484.1
O2 (g) 0
CO2 (g) -393.5
H2O (l) -285.8
f. How much energy is released when 20.2 grams of C2H4O2 is reacted?
