Answer:
The correct answer is option a.
Explanation:
Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in (
).
J = diffusion flux
A = Unit area A through which atoms moves.
M = mass of atoms passes in t interval of time.
Answer:
B
Explanation:
cause surface area of solute is not necessary for solution
<u>158 pm</u> is the distance Between equatorial Fluorine atoms in PF₅<u>(</u>Phosphorus pentafluoride).
<h3>What is
Fluorine?</h3>
The chemical element fluorine has an atomic number of 9 and the symbol F. The lightest halogen, it is an extremely poisonous, pale yellow diatomic gas under normal conditions. It is exceedingly reactive and, as the most electronegative element, reacts with all other elements with the exception of argon, neon, and helium.
Fluorine is the 24th most abundant element overall and the 13th most abundant on Earth. In order to decrease the melting temperatures of metal ores for smelting, fluorite, the main mineral source of fluorine, was added. The Latin verb fluo, which means "flow," gave the mineral its name. Fluorite was first described in 1529.

Answer:
60 mL
Explanation:
200 mL = 0.2 L
We know that:
Molarity = Moles / Liters
So:
4.20 M = moles / 0.2 L
moles = 4.20 x 0.2 = 0.84
Then:
14.0 M = 0.84 moles / Liters
Liters = 0.84 moles / 14.0 M = 0.06 L
Since they want the answer in mL, convert 0.06 to get 60 mL
I think its a covalent bond because carbon is positively charged and iron is positively charged too which makes the bond covalent. hope it helps
