[H3O+] is just the same with [H+]. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14.

When the temperature is cold, Tim's tires look under-inflated. This is because the air molecules in the tire slow down causing their kinetic energy to decrease and volume to contract. slow down, decrease, contract on USA Test Prep its A.
