What is the pH of a solution with a 3.2 x 10−6 M hydronium ion concentration?

Summarize possible ways in which phases of matter could combine to form a solution.

Which element is least likely to undergo a chemical reaction

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
