    For 10, Kc = 4. Initial conc : ethanol = 1 mol Ethanoic acid = 1 mol Ethyl ethanoate = 0 mol Water = 0 mol Final conc : Ethanol =(1-x)mol Ethanoic acid=(1-x)mol Ethyl ethanoate = x mol Water = x mol Kc = 4 = [x] [x] /[1-x] [1-x]...

    For 5, find the mass of Ni. It is 2 g. We know 1 mole of any substance = 6.02 * 10^23 particles thus, 1 mole of Ni = 58.7 g, which equals 6.02 * 10^23 so, 2 g = 2.05 * 10^22, ie A

    Hey any idea how 2 solve this?? Ans is C

    the ans is D...1 only as Mr = Mass/No of moles... Rearranging the equation , v gt p = P * R* T * n / Mass. we know density = mass/ volume..so d/m = 1/volume... Rearranging it once agn, v gt ...pv = nRT

    Here use d eqn pv = nRT, u know the pressure = 101kPa To find no of moles of ice, find the mass, d*v = 1 g, n Mass/Mr...so no of moles = 0.0556 R = 8.213 T = 596 K Substitute d values, to get d ans, C
