Butane (C4H10) used in a grill burns according to the following reaction:
2 C4H10( g) + 13 O2(g) → 8 CO2(g) + 10 H2O(g) ΔH°rxn = -5756.6 kJ
A certain piece of steak needs to absorb 539 kJ to fully cook. Calculate the mass of CO2 emitted if only 15% of the heat produced is actually absorbed by the steak.
