Answer:
i wish i knew so i could help
Explanation:
All those compounds are ionic.
Then they dissociate into ions when they are in water.
I will write the dissociation equations. The charges of the ions is indicated inside parenthesis.
KI -> K (+) + I (-) => two ions
K2SO4 -> 2 k(+) + SO4 (2-) -> three ions
NaCl -> Na(+) + Cl(-) => two ions
KBr -> K(+) + Br(-)
As you se every molecule of the compound K2SO4 dissociates into three ions, while the other compounds dissociate into two ions. Given that the decrase in the freezong point of water is proportional to the number of particles dissolved, the K2SO4 will lower the freezing point the most.
Answer: option B. K2SO4
Answer:
4. fact
5.fact
I think this is all fact no evidence
He ability to rust is a chemical property of iron. The metal silver does not rust, but eventually a darker substance called tarnish forms on its surface. The chemical properties of copper cause it to become a blue-green color when it is exposed to air
Answer:
ok
Explanation:
In anisotropic refinement, this motion is fitted as an ellipsoid, the center of which lies inside the circle of motion, while the atom is loated on its periphery. This effect makes the bond distance appear shorter.
