which of the following is true of a solution with a [h3o+] of 1.0x10-4m?
it has a high hydronium concentration and a low hydroxide concentration, so it is acidic.
it has [h3o+]= 1.0x10-7m so it is acidic.
it has [oh-]= 1.0x10-14m so it is neutral.
it has a low concentration of hydronium and a high hydroxide so it is basic.
it has [oh-]= 1.0x10-7m so it is acidic.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
