Is it C?View attachment 63773
can someone help me with this question?
I had the same problem in this question when I solved this paper but now after repeated tries I was able to solve it correctly Alhamdulillah.
First find the value of the constant K as the angle of deflection is directly proportional to the charge mass ratio
PROTON:
Angle=+15 Charge= + mass= 1
15= k(+/1) thus K=+15
Option 1 :
Charge= +1-2= -1
mass= (atomic mass) 1+2=3
k=+15
Angle= (+15)*(-1/3)= -5..............option 1 correct
Option 2 :
Charge = +3-5 = -2
mass=3+3 =6
K=+15
Angle = (+15)*(-2/6) = -5..................option 2 is also correct
Option 3 :
Charge :4-1 = +3
mass=4+5 =9
K=+15
Angle = (+15)*(+3/9) = +5.......................Option 3 is incorrect.
Ans: B
Thank you :O
Its B, since yellow ppt is formed by silver iodide.Need helpView attachment 63782
If you find the ratio of salt to sulphite( simply by finding moles of salt and sulphite according to the info given) it comes out to be 2:1
& the equation shows 1 mole of sulphite looses 2 electron, therefore 2 mol of metallic salt gain those 2 electrons or 1 mol of metallic salt gains 1 mol of electron
therefore new O.N. of metal = +3-1=+2!

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
