Which one of these salts will form a neutral solution on dissolving in water? KNO2 NaCN NaCl NH4NO3 FeCl3

NaCl

Explanation:

Salts whose ion cannot hydrolyse form neutral solutions; not having alkaline nor acidic properties.

All the other salts would dissociate to form solution or strong acid ad weak bases or vice versa, which then determines their alkalinity or acidity: all except sodium chloride, NaCl.

I hope this explanation was helpful and clear.

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
