Potassium hydroxide dissolves and completely dissociates in water and a solvation sphere of water molecules forms around the ions. This solute-solvent interaction and makes the beaker warm.

Calculate the h3o+ concentration in a solution of acetic acid if the concentration of molecular acetic acid present at equilibrium is 9.97x10^-3 m and k for the dissociation is 1.86x10^-5. ch3cooh(aq)+h2o(> h3o^+(aq)+ch3coo^-(aq)

What layer of the atmosphere is directly above the troposphere?

Compare and contrast the bohr model and the electron cloud models of the atom.
