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.

Express your answer with the appropriate units

Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium equation.The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved CO2. For a CO2 partial pressure of 3.2×10–4 bar in the atmosphere, what is the pH of water in equilibrium with the atmosphere? (For carbonic acid Ka1 = 4.46× 10–7 and Ka2 = 4.69× 10–11).
