Question
Sulfur dioxide is the pollutant that most commonly gives rise to this phenomenon. For 10 points each:
[10e] Name this phenomenon whose negative impacts are characterized by precipitation with low pH.
ANSWER: acid rain [or acid precipitation; prompt on rain]
[10m] Besides the resulting biological damage, acid rain creates problematic weathering of structures from how it breaks down this ionic compound of limestone and marble.
ANSWER: calcium carbonate [or CaCO3 (“C-A-C-O-3”); prompt on calcite or aragonite; reject “carbonate”]
[10h] Nitrogen oxides produced by these devices can react with sulfur dioxide to produce acid rain. Lead residue reduces performance in these devices by inhibiting metals such as palladium needed for a redox reaction to occur.
ANSWER: catalytic converters
