Determine what would be the concentration of the final solution If you take a ten mili litres portion of the stock solution and dilute it to a total volume of 0.250 Litres,?
The orbital energy of any atomic species depends on factors other than the principle quantum number n and any given energy level in H is more stable than the same level in H+.
it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.338 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibri..
