I believe it is going to be (A). Pardon me if it is not.
Answer: The answers are the first and third options.
Assuming that the concentration is given as 0.010M (there is a big difference between m and M):
Sulfuric Acid (H2SO4) is a strong acid, and thus will completely dissociate into ions in solution. This will result in
For each mole of H2SO4, there will be 2 moles of H+. So, [H+] = 0.0200M
Observation(s).But in definition data is facts, figures, and other evidence gathered through your observations.
