Some commercial drain cleaners contain a mixture of sodiumhydroxide and aluminum powder. When the mixture is poured down aclogged drain, the following reaction occurs:
2NaOH(aq) + 2Al(s) + 6H2O(l) →2NaAl(OH)4(aq) + 3H2(g)
The heat generated in this reaction helps melt away obstructionssuch as grease, and the hydrogen gas released stirs up the solidsclogging the drain. Calculate the volume of H2 formed at23°C and 1.00 atm if 3.12 g of Al are treated with an excess ofNaOH.
The metabolic oxidation of glucose,C6H12O6, in our bodies producesCO2, which is expelled from our lungs as a gas:
C6H12O6(aq) + 6O2(g)→ 6CO2(g) + 6H2O(l)
Calculate the volume of CO2 produced at bodytemperature (37°C) and 0.970 atm when 24.5 g of glucose is consumedin this reaction.
Calculate the volume of oxygen you would need, at 1.00 atm and298 K, to completely oxidize 50.0 g of glucose.
