Calculate the number of moles of chlorine gas needed to form 14 moles of iron (iii) chloride

Explanation:

(a) Balanced equation

You haven't given the complete reaction, but we can use a partial equation so long as Cl is balanced.

3Cl₂ + … ⟶ 2FeCl₃ + …

(b). Calculation

You want to convert moles of FeCl₃  to moles of Cl₂

The molar ratio is 3 mol Cl₂:2 mol FeCl₃

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

i think   the answer is c hope i'm right
