NH_(3) solution was added to four semple solution in difference test tube and found the following observation about the precipitate. a. White ppt which is solution in oxcess of NH_(3) solution b.On heating which is white in cold but yellow on heating c. The cation present in (b) forms white ppt , with hypo solution which give black ppt on heating d. The cation present in (c ) forms soluble complex with excess of NH_(3) solution White ppt in (c) and the soluble complex from white ppt with the type solution is//are

IIB (arsenic group ) sulphides are solution in YAS if cone HCI isadded to this soluble portion colour red ppt are formed Write reaction

Compound (X) C_(6)H_(5)O gives yellow coloured ppt with 2,4 DNP but does not give red colored ppt with Fehiling's solution (X) on treatement with NH_(2)OH H^(+) gives compound (Y) C_(6)H_(5)NO (Y) when treated with PCl_(5) gives isomeric compound (Z) . (Z) on hydrolysis gives propanoic acid and aniline. what will be the correct structure of (X) ,(Y) and (Z) ?

If the length of the tangent drawn from (f, g) to the circle x^2+y^2= 6 be twice the length of the tangent drawn from the same point to the circle x^2 + y^2 + 3 (x + y) = 0 then show that g^2 +f^2 + 4g + 4f+ 2 = 0 .

f(x) ,g(x) and h(x) are all continuous and differentiable functions in [a,b] . Also altcltb and f(a)= g(a)=h(a ). Point of intersection of the tangent at x=c with chord joining x=a and x=b is on the left of c in y= f(x) and on the right in y=h(x) . And tangent at x=c is parallel to the chord in case of y=g(x) . Now answer the following questions. If c=(a+b)/(2) for each b , then:
