A would because its amplitude is higher than B's Hope this helps :D
Answer:
D
Explanation:
Petroleum is one of the top ingredients that makes of gas. When it burns it releases exhaust made of carbon dioxide into the atmospere which has a wide range of effects.
Ka expression for any substance:
Ka = [H+] [A-] / [HA]
In this case,
Ka = [H+][C₃H₅O₃-]/[C₃H₆O₃]
1.4 x 10⁻⁴ = [H+] [C₃H₅O₃-] / [C₃H₆O₃]
pKa = -log(Ka)
pH = -log([H+])
The difference between pKa and pH is that pH is the negative logarithm of only the concentration of hydrogen ions, while pKa is the negative logarithm of the ratio of the product of the concentrations of hydrogen ions and concentration of base to the concentration of acid.
