Consider the following combustion reaction: 2 C4H10 + 13 02 → 8 CO2 + 10 H20. 125 g
of C4Hjo react with 415 g of O2.
a) Which substance is the limiting reactant?

Use the standard enthalpies of formation for the reactants and products to solve for the δhrxn for the following reaction. (the δhf of c2h4 is 52.26 kj/mol, co2 is -393.509 kj/mol, and h2o is -241.818 kj.) c2h4 (g) + 3o2(g) 2co2 (g) + 2h2o(g) δhrxn = the reaction is .
