Question
1. The combustion of acetylene is:
2 C2H2 + 5 O2 4 CO2 + 2 H2O ΔHo = -2511 kJ
11a. (5 pts) How much heat is produced if 85 g
C2H2 is combusted with excess O2?
2 C2H2 + 5 O2 4 CO2 + 2 H2O ΔHo = -2511 kJ

The problem tells you that you obtain 2511 kJ heat for burning 2*26 or 52 g C2H2. Instead of using 52g the problem is using 85g so the heat produced must be
2511 kJ x (85/52) = ?
2511 kJ x (85/52) = ?
