Find the general solution of the equation, sin3x+cos4x-4sin7x=cos10x+sin17x .

Given K_(sp)(AgI)=8.5xx10^(-17) . The solubility of AgI in 0.1M KI solution is

(a) 10 g of a certain non-volatile solute were dissolved in 100 g water at 20^(@) C . The vapour pressure was lowered from 17.3555 mm to 17.2350 mm , calculate m . wt. of solute. (b) The vapour pressure of pure water at 25^(@)C is 23.62 mm . What will be the vapour pressure of a solution of 1.5 g of urea in 50 g of water?

Three suggestion are made for ways to removes silver ions from solution: a. Make the solution 0.01M in Nal . b. Buffer the solution at pH = 13 . c. Make the solution 0.01M Na_(2)S . What will be the equilibrium silver ion concentartion in each case? which course of action is most effective in removing Ag^(o+) ions? K_(sp) (AgI) = 8.5 xx 10^(-17), K_(sp) (AgOH) = 2 xx 10^(-8) , K_(sp) (Ag_(2)S) = 5.5 xx 10^(-51)
