2.50 grams of XeF4 is introduced into an evacuated 3.00 liter container at 80.0 °C. Find the pressure in atmospheres in the container.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

i believe the answer is a.

i'm assuming that the correct answer is indeed the first one/ "a"..

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
