Which two substances are generally required for photochemical smog to occur?
A) the presence of phosphorous and nitrates
B) the presence of sunlight and phosphorous
C) the presence of sunlight and volatile organic compounds
D) the presence of phosphorous and nitrogen fixing bacteria
Photochemical Smog
A type of air pollution created when sunlight reacts with nitrogen oxides and at least one volatile organic compound in the atmosphere.
Volatile Organic Compounds
Organic chemicals that have a high vapor pressure at ordinary room temperature, making them significantly evaporative and potentially harmful to the environment and human health.
Sunlight
The natural light emitted by the Sun, providing energy that supports the majority of life on Earth through photosynthesis.

Final Answer :
C
Explanation :
Photochemical smog occurs when sunlight reacts with volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the atmosphere. The reaction produces ground-level ozone and other pollutants. The presence of sunlight and VOCs are the two main requirements for the formation of photochemical smog. Phosphorus and nitrogen fixing bacteria do not contribute to the formation of photochemical smog.
