If a pork roast must absorb 1500kJ to fully cook, and if only 11% of the heat produced by the barbeque is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast? Express your answer using two significant figures. The propane fuel (C3H8) used in gas barbeques burns according to the following thermochemical equation: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)ΔH∘rxn=−2044kJ
Comment in case of any doubt.

The propane fuel (C3H8) used in gas barbecues burns according to the following equation: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)ΔH∘rxn=−2044kJ PART A: If a pork roast must absorb 2.3×103kJ to fully cook, and if only 10.% of the heat produced by the barbecue is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast?
The propane fuel (C3H8) used in gas barbeques burns according to this thermochemical equation. If a pork roast must absorb 1.5×103 kJ to fully cook, and if only 15 % of the heat produced by the barbeque is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast?
he propane fuel (C3H8) used in gas BBQs burns according to this thermochemical equation: C3H8 + 5O2 --> 3CO2 + 4H2O delta H = -2217kJ If a pork roast must absorb 1.6x10^3 kJ to fully cook, and if ONLY 10% of the heat produced by the BBQ is actually absorbed by the roast, what mass of CO2 is emitted into the atmosphere during the grilling of the pork roast.
a) Determine the mass of CO2 produced by burning enough of methane to produce 1.50×102kJ of heat. CH4(g)+2O2(g)→CO2(g)+2H2O(g)ΔH∘rxn=−802.3kJ b) Determine the mass of CO2 produced by burning enough of propane to produce 1.50×102kJ of heat. C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)ΔH∘rxn=−2217kJ c) Determine the mass of CO2 produced by burning enough of octane to produce 1.50×102kJ of heat. C8H18(l)+25/2O2(g)→8CO2(g)+9H2O(g)ΔH∘rxn=−5074.1kJ d) Which fuel contributes least to global warming per of heat produced? methane propane octane
GIVEN INFO LP gas burns according to the following exothermic reaction: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g) ΔH∘rxn= −2044kJ What mass of LP gas is necessary to heat 1.4 L of water from room temperature (25.0 C) to boiling (100.0 C)? Assume that during heating, 16% of the heat emitted by the LP gas combustion goes to heat the water. The rest is lost as heat to the surroundings. Express your answer using two significant figures.
