In neutral or faintly alkaline solution, 8 moles of permanganate anion quantitatively oxidise thiosulphate anions to produce X moles of a sulphur containing product. The magnitude of X is

MnO_4^(-) ions are reduced in acidic condition to Mn^(2+) ions whereas they are reduced in neutral condition to MnO_2 . The oxidation of 25 ml of a solution X containing Fe^(2+) ions required in acidic condition 20 ml of a solution Y containing MnO_4^(-) ions. What volume of solution Y would be required to oxidise 25 ml of solution X containing Fe^(2+) ions in neutral condition ?

A dilute solution contains 'x' moles of solute A in 1 kg of solvent with molal elevation constant K_(b) . The solute dimerises in the solution according to the following equation. The degree of association is (a) : 2A hArrA_(2) The van't Hoff factor will be:

A dilute solution contains 'x' moles of solute A in 1 kg of solvent with molal elevation constant K_(b) . The solute dimerises in the solution according to the following equation. The degree of association is (a) : 2A hArrA_(2) The degree of assoicition is equal to : a) a = ((K_(b)x - /_\T_(b)))/(/_\T_(b)2) b) a = (2(K_(b)x - /_\T_(b)))/(K_(b)x) c) a =2 + (2/_\T_(b))/(K_(b)x) d) a = (/_\T_(b))/(2K_(b)x)

Two liquids X and Y on mixing form an ideal solution. The vapour pressure of the solution containing 3 mol of X and 1 mole of Y is 550 mm of Hg. But when 4 mol of X and 1 mol of Y are mixed, the vapour pressure of the solution thus, formed is 560 mm of Hg. what will be the vapour pressure of the pure X and pure Y at this temperature?

A dilute solution contains 'x' moles of solute A in 1 kg of solvent with molal elevation constant K_(b) . The solute dimerises in the solution according to the following equation.

The vapour pressure of two pure liquids A and B are 50 and 40 torr respectively. If 8 molrs of A is mixed with x moles of B , then vapour pressure of solution obtained is 48 torr. What is the value of x.

A certain radioactive isotope ._(Z)^(A)X(t_(1//2)=100 days) decays to ._(Z-2)^(A-8)Y . If 1 mole of ._(Z)^(A)X is kept in sealed container , how much He gas will accumulate at STP in 200 days?
