JoinSet theory
"In a battle, 70% of the combatants lost one eye, 80% an ear, 75% an arm, 85% a leg, x% lost all four organs. Find the minimum value of x."
Plz explain the approach and the steps of the solution in detail...
prediction of groups in periodic table
Can someone explain how to predict the group of an element with electronic configuration
capacitors + fluids
very small doubt.
case 1: lower plate has -sigma charge density
case 2: lower plates has +sigma charge density
will liquid rise in both the cases ??
...

limits
can someone explain why limit wont exist in the first 2 if f(a) is an integer? and what did they do in the ques

Solubility
You and a friend are studying for a chemistry exam. What if your friend tells you that since acids are very reactive, all salts are more soluble in aqueous solutions of acids than in water? How would you explain to your friend that this is not true? Use a specific example to defend your answer.
what examples can we take?...
conc. cell
if by chnce i want to calculate the emf value do we apply like conc. cell formula here or ?? do we calc ulate the new emf of both the solution and then do the normal way to get to emf??

Limits doubt
While solving limits, we sometime factor out and cancel some terms from numerator and denominator. However doesnt that fundamentally change the function. As we cancel terms, we change how it looks on a graph so shouldnt it change the function itself for which we are calculating limit
