A compound is a substance made up of 2 or more elements
The answer is (3) pH 3 to pH 1. The pH is related to the concentration of H3O+ with the relationship: pH = -lg c(H+). So when concentration of H3O+ increase, the pH will decrease. And decrease 2 when when increase hundredfold. Because 100=10^2.

Answer:
The volume would be 6,4 L
Explanation:
We use the Boyle Mariotte formula, according to which for a certain mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2
V2= (P1xV1)/P2= (3,2 atm x 2, 00 L)/1,00 atm= 6,4 L
