Question
This compound is the heavier product of the water-gas shift reaction. For 10 points each:
[10m] Name this compound whose electrochemical reduction can generate useful fuels and feedstocks, like ethanol and formic acid. Hydrocarbon “solar fuels” are produced using this compound as a primary feedstock.
ANSWER: CO2 (“C-O-2”) [or carbon dioxide]
[10h] The most promising current catalysts for electrochemical CO2 reduction are surfaces of this metal. Strained cyclo·octynes were developed to replace catalysts of this cyto·toxic metal in bio·orthogonal reactions.
ANSWER: copper [or Cu]
[10e] Selectivity in CO2 reduction systems is limited by competition with a reaction that “evolves” this gas. The formation of this gas at a platinum electrode is the standard used to define zero volts for standard reduction potentials.
ANSWER: hydrogen [or H2 (“H-2”)]
