In 1L saturated solution of AgCI [K_(sp) (AgCI) = 1.6 xx 10^(-10)], 0.1 mol of CuCI [K_(sp)(CuCI) = 1.0 xx 10^(-6)] is added. The resultant concentration of Ag^(+) in the solution is 1.6 xx 10^(-x) . The value of "x" is.

The solubility product of AgI at 25^(@)C is 1.0xx10^(-16) mol^(2) L^(-2) . The solubility of AgI in 10^(-4) N solution of KI at 25^(@)C is approximately ( in mol L^(-1) )

The tops of two poles of height 16m and 10m are connected by a wire of length l metres.If the wire makes an angle of 30o with the horizontal,then l=(a)26 (b) 16 (c) 12 (d) 10

The rate of a reaction increases four-fold when the concentration of reactant is increased 16 times. If the rate of reaction is 4 xx 10^(-6) mol L^(-1) s^(-1) when the concentration of the reactant is 4 xx 10^(-4) mol L^(-1) . The rate constant of the reaction will be

The heat librerated on complete combustion of 1 mole of CH_(4) gas to CO_(2)(g) and H_(2)O(l) is 890 kJ. Calculate the heat evolved by 2.4 L of CH_(4) on complete combustion.

For the equilibrium H_(2)(g)+CO_(2)(g)hArr hArr H_(2)O(g)+CO(g), K_(c)=16 at 1000 K. If 1.0 mole of CO_(2) and 1.0 mole of H_(2) are taken in a l L flask, the final equilibrium concentration of CO at 1000 K will be
