    Mod 7 UV Catastrophe Question

    Hey guys, could anyone explain to me how classical theory of light assuming that every oscillator having the same kinetic energy at a given temperature is an incorrect assumption leads to the ultraviolet catastrophe. Also, I get how quantising energy abides by the law of conservation of energy...

    Buffer Systems

    Bit confused with this, if hydroxide reacts with the weak acid CH3CH2COOH, wouldn't that decrease concentration of weak acid, thus resulting in equilibrium shifting left. Or has the consumption of H+ and partial consumption of CH3CH2COOH still result in a shift to the right/

    K Calculation Questions

    Theres been this part of calculations that I never understood. Say this question, a solution of iorn (II) hydroxide has a pH of 9.42. Calculate the solubility, in g/L of iorn (II) hydroxide in this solution. You find [OH-] = 10^-4.58, since Fe(OH)2 --> Fe2+ + 2OH-, why can't we just half the...

    Redox

    Hey guys, I'm so lost on how to do redox reactions. We did em in year 11 and I completely forgot. Say for this titration q: 25 mL of hydrogen peroxide was made up to 250 mL with water, from this solution 25 mL was titrated against 23.45 mL of 0.0200 mol L-1 potassium permanganate solution...
