Solution: Determine the mass of CO2 produced by burning enough of octane to produce 2.25x102 of heat.C8H18(l) + 25/2 O2(g) → 8 CO2(g) + 9 H2O(g); ΔH˚rxn= - 5074.1 kJ

Problem

Determine the mass of CO2 produced by burning enough of octane to produce 2.25x102 of heat.

C8H18(l) + 25/2 O2(g) → 8 CO2(g) + 9 H2O(g); ΔH˚rxn= - 5074.1 kJ
