There was one question like two white
substances are mixed in aqueous solution
and a yellow product is formed. KCl and
PbNO3 or KNO3 or PbCl or Both nitrates or
both chlorides. (Plzz check this one not very
sure…)
Liquids were water and oil (With replacement)

b) 2nd and 3rd equation only
c) 1st 2nd and 3rd equation
d) insufficient
The question had asked what all info is
required to minimize/maximise(yaad ni) z
(Similar solved example from textbook for reference)
d) is E+Y
Chemistry
Yr in this question there was a reverse arrow from B to A too

Maths
The following Q is incomplete or somewhat
incorrect, kindly chip in if you recall it.
Maths
Basic lpp question
Two inequalities and Z=() were given and
options had optimal solutions with value of Z.
Had to choose which of them was correct (dont
remember the equations)
Bro do you remember the LR question above
and the maths tangent/normal question
Physics
options had relation between T2 T3 and T4 and
sin/cos(alpha) and sin/cos(beta)
Chemistry Which property can be used to know purity of a substance? Mp Bp magnetic or none crystal lattice was also an option here Chemistry Three compounds given with same IUPAC name except difference in R/S and E/Z nomenclature, assign R/S/E/Z correctly Chemistry Some compound given then asked if trans isomer will have lesser/more BP etc (don’t remember full Q) Physics If two particles of mass m and charge q each have same value of Gravitational force and Electrostatic force separated by distance r, and value of (4πε 0 G)=10-20 then the value of (q/m) is? (answer was 10-10^ I think) If sand from something is slowly poured onto a weight balance at a steady rate λ and then a mass of M is weighted on the scale the weight measured is
a) λt + √2gh
b) λt c) d) Yaad nahi hai but if i remember it right the options were solvable using dimension checking Physics The SI units of Luminance is? 1) dc/cm^2 2) dc/m^2 3) cd/cm^2 4) cd/m^2 (This is the exact Q, with correct options) Chemistry The ratio of molecular formula to empirical formula of glucose is? (answer was 6)
