Which solution would have the lowest freezing point: 0.1 M Magnesium Phosphate Solution
0.1 M Calcium Chloride Solution
0.1 M Potassium Chloride Solution
0.1 M Sodium Chloride Solution

Potasium

Explanation:Urea and glucose do not dissociate in solution. Sodium chloride gives two ions and potassium sulfate gives three ions per formula unit.

Therefore, the effective number of particles is maximum in potassium sulfate , and it shows the maximum depression in freezing point.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
