Gaseous iodine pentafluoride can be prepared by the reaction of solid iodine and gaseous fluorine: I2(s)+5F2(g)–>2IF5(g)
A 10 L flask is charged with 29 g of I2 and 2 atm of F2 at 25C. The flask is heated to 100C until one of the reagents is completely consumed. What will be the total pressure in atm of the final products in the flask at 100C? (Assume ideal gas behavior).

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

the answer is a for sure mark brainliest i had got this right on usatestprep
