The very stable compound SF6 is made by burning sulfur in an atmosphere of fluorine. S8(s) + 24F2(g) → 8SF6(g)
If you need 2.50 moles of SF6, you will need to use
(A) 0.313 moles of S8 and 7.50 moles of F2.
(B) 1.00 moles of S8 and 24.0 moles of F2.
(C) 0.125 moles of S8 and 3.00 moles of F2.
(D) 8.00 moles of S8 and 24.0 moles of F2.
(E) 2.00 moles of S8 and 12.0 moles of F2.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

1 is the answer to this problem

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
