Why does a neutral solution have a of 7.0? In a neutral solution, the [H3O+]=1*10^-7 at 25∘C. pH=-log[1*10^-7]=7.0. In a neutral solution, the [H3O+]=1*10^7 at 25∘C. pH=log[1*10^7]=7.0. In a neutral solution, the [H3O+]=1*10^14 at 25∘C. pH=0.

Newton's Second Law of Motion is F = ma. Closely related to this is Hooke's Law, F = - kx, which describes the force needed to restore the displacement of a "rigid" body, such as a spring.

An automobile tire at 30°C has a pressure of 3.00 atm. Temperature decreases to - 5°C. Assume that there is no volume change in the tire.
