Choose the aqueous solution below with the lowest freezing point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. 0.075 m KNO2
0.075 m (NH4)3PO4
0.075 m NaBrO4
0.075 m KCN
0.075 m Li Cl

Explanation:

All the given solution has equal concentration of solute so the depression in freezing point will depend upon the van't Hoff factors  . If we treat all as strong electrolyte

the  van't Hoff factor of KNO₂ = 2 (1 + 1 )

(NH4)₃PO4 = 4  ( 3 +1 )

NaBrO4 = 2 ( 1 + 1 )

KCN = 2

LiCl = 2

So  van't Hoff factor is largest in NH4)₃PO4 so depression in freeing point will be largest in it so lowest freezing point of water will be in case of solution of NH4)₃PO4 .

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
