D, It is a flow of protons, is the best answer. Electricity is the flow of electrons, not protons.
Answer:
all of these are properties of metalloids
Molar solubility of AgCl will be 0.59 ×
M.
The amount of a chemical that can dissolve in one liter of a solution before reaching saturation is known as its molar solubility. This implies that the quantity of a substance it can disintegrate in a solution even before the solution becomes saturated with that particular substance is determined by its molar solubility.
A compound's molar solubility would be the measure of how many moles of such a compound must dissolve to produce one liter of saturated solution. The molar solubility unit will be mol L-1.
Calculation of molar solubility:
Given data:
M = 0.30 M
= 1.77 × 
The reaction can be written as:
AgCl ⇔ 
s s (s+0.30)
= [
]+ [
]
1.77 ×
= s (0.30)
s = 1.77 ×
/ 0.3
s = 0.59 ×
M
Therefore, molar solubility of AgCl will be 0.59 ×
M.

So we just need to do some conversions. We can convert gallons (gal)---> liters (L) just using a few conversion factors and some simple stoichiometry.
Here are the conversion factors:
1 gal= 3.78541 L
Here is how to do the problem:
12 gal x 3.78541 L/1 gal = 45.4249 L
The final answer with significant figures (there are two significant figures) is:
45 L
