An equilibrium mixture is 1.0 L flask contains 0.70 mol HI (g) and 0.10 mol each of I2 (g) and H2 (g). If 0.30 mol H2, 0.60 mol I2, and 0.20 mol HI are added to this equilibrium mixture how many moles of each gas will be present when equilibrium is reestablished?



Can anyone help?

The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side.

hope that helps.

2HI ---> I2 + H2

equilibrium constant = (mols of I2)(moles of H2)/(HI)^2

Then add up all the mols that were introduced and find Q and compare it to K depending on if Q is less than or greater than K the reaction will shift to a certain direction. So then setup an ICE table with the total concentrations as your initial values. I didn't want to help too much, so see what you can do and if not ask and I'll try to help.

I was actually taught stick first. That was tough at first.

I only post that bc didn't you ask for help in a stoichiometric chemistry problem once?

Last time i needed help with stoichmetery was in the 10th grade lol. I think the only time I asked for HW help was for math, mainly i needed baselien bums help and what a coincedence i think need his help again to solve some problems for me because i don't to take the time and do them myself, because baseline bum could probably do them pretty fast. so what's the point.
