Chemistry

Part A) Charcoal is primarily carbon. What mass of CO2 isproduced if you burn enough carbon (in the form of charcoal) toproduce 5.40×102kJ of heat? The balanced chemical equation is asfollows: C(s)+O2(g)→CO2(g),ΔH∘rxn=−393.5kJ

PartB)

What mass of natural gas (CH4) must you burn to emit 260 kJ ofheat?

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 reactionof 375 g of NH3.

Express your answer with the appropriate units
