Homework Answers
Balanced equation : 2 C31H64(S) + 94 O2(g) ----> 62 CO2(g) + 64 H2O(l)
Dn = np-nR = 62- 94 = 32
Work done(w) = -DnRT
= -32*8.314*298
= -79.28 kj
per mole of Wax(C31H64) Work done(w) = -79.28/2 = - 39.64 kj
Answer: w = -39.64 kj/mol

What mass of water is produced from the complete combustion of 8.90x10-3 g of methane?
Complete combustion of methane When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g) + O2(g) → CO2 (g) + H2O(g) This type of reaction is referred to as a complete combustion reaction.Part C What mass of water is produced from the complete combustion of 8.90x10-3 g of methane? Express your answer with the appropriate units.
