Part A) Charcoal is primarily carbon. What mass of CO2 is produced if you burn enough carbon (in the form of charcoal) to produce 5.40×102kJ of heat? The balanced chemical equation is as follows: C(s)+O2(g)→CO2(g),ΔH∘rxn=−393.5kJ
PartB)
What mass of natural gas (CH4) must you burn to emit 260 kJ of heat?
CH4(g)+2O2(g)→CO2(g)+2H2O(g)ΔH∘rxn=−802.3kJ
Express the mass in grams to three significant figures.
Part C)
Ammonia reacts with oxygen according to the equation:
4NH3(g)+5O2(g)→4NO(g)+6H2O(g)ΔHrxn=−906kJ
Calculate the heat (in kJ) associated with the complete reaction of 375 g of NH3.
