Question

ocean acidification is the result of cars releasing _______.
a. acid directly into the atmosphere
b. carbon dioxide that forms acid when it dissolves in water
c. sulphur dioxide that forms acid in the atmosphere
d. nitrogen oxides that form acid in the atmosphere

please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

Ocean acidification occurs when excess carbon dioxide (a major emission from cars) dissolves in seawater. This forms carbonic acid ($\text{H}_2\text{CO}_3$), which lowers the ocean's pH. Cars do not release acid directly, and sulfur/nitrogen oxides primarily cause atmospheric acid rain, not ocean acidification.

Answer:

B. carbon dioxide that forms acid when it dissolves in water
