The answer you are looking for is B.
<u>Answer:</u> The amount of sodium thiosulfate required is
moles
<u>Explanation:</u>
Moles of
solution given = 0.0000524 moles
The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:

By Stoichiometry of the reaction:
2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate
So, 0.0000524 moles of potassium iodate will react with =
of sodium thiosulfate
Hence, the amount of sodium thiosulfate required is
moles
Answer:
Eight
Explanation:
The L shell only holds eight electrons.
You need to use the formula--> P1V1= P2V2 (Boyles's law)
P1= 14 bar
V1= 312 mL
P2= ?
V2= 652 mL
now we plug the values into the formula.
(14 x 312) = (P2x 652)
P2= (14 x 312)/ 652= <span>6.70 bar</span>
