chem

Answer 1

@JoannaBlackwelder A or B?

Answer 2

Yep, I get one of those.

Answer 3

Sorry been a while, I am more of organic, but I figured it out. I got 1.42m

Answer 4

Hm, that's not what I got.

Answer 5

Did you do it like this?

Answer 6

2HI--> H2 +I2
I 1.6m 0 0
C -x X X
E 1.6x X X

k=x^2/ (1.6-x)^2
k=1.42m

Answer 7

Make snese

Answer 8

No, I get the equilibrium expression for HI to be 1.6-2x

Answer 9

Since 2 moles of it decompose for each 1 mole of H2 and I2

Answer 10

Remember 2 moles HI so ()^2

Answer 11

Look at my work

Answer 12

2HI intial, when you have any number of moles you take it to the the power, example 3HI then (HI)^3

Answer 13

@n648c788 what chemistry classes have you taken?

Answer 14

The decompsition just means you will make the HI -x, and H x, Ix

Answer 15

All but Organic is what I know best, but If I see examples I can solve old problems

Answer 16

HI would be -2x not -x

Answer 17

Yeah you are right little error, but it is worked the same way
