Question

What change would not result in the equilibrium position shifting to the left?

2 A (g) + B (s) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. 3 C (g) + Energy

Increasing the pressure
Adding more of gas C to the system
Removing some of A from the system
Cooling the system

Answer 1

@taramgrant0543664

Answer 2

im going with b !

Answer 3

Adding more C would shift the equilibrium to go left ward

Answer 4

@taramgrant0543664 so im correct?

Answer 5

You want which change does NOT make the equilibrium shift left

Answer 6

so a would be correct @taramgrant0543664 :)

Answer 7

@JoannaBlackwelder you there?

Answer 8

Yeah, increasing the pressure shifts the equilibrium toward less gas molecules, so no, not a.

Answer 9

yes Joanna has that right it would not be A

Answer 10

MY LAST OPTION IS C MAKES THE MOST SENSE

Answer 11

Removing Some of A from the system will shift the reaction to go left

Answer 12

so c will be ocrrect? @JoannaBlackwelder

Answer 13

No, we want to shift the equilibrium right.

Answer 14

so my final choice is d

Answer 15

Haha, yep. Cooling the system removes energy, which is a product. So it will shift right. :-)

Answer 16

haha ok

Answer 17

The space shuttle uses ammonium perchlorate and aluminum to create an explosive reaction. The reaction can be seen below.

2 NH4ClO4 (s) + 2 Al (s) yields Al2O3 (g) + 2 HCl (g) + 2 NO(g) + 3 H2O (g)

Which of the following statements correctly describes this reaction?

Aluminum is oxidized because it lost electrons.
Aluminum is oxidized because it gained electrons.
Oxygen is oxidized because it lost electrons.
Oxygen is oxidized because it gained electrons.

Answer 18

im going with b @JoannaBlackwelder

Answer 19

Why do you think it is b?

Answer 20

cause te eqation is gainign electrons

Answer 21

Hm, the whole reaction is gaining electrons? Why would that mean that Al is gaining electrons?

Answer 22

true so b is incorrect ;(

Answer 23

Yes

Answer 24

so a is correct

Answer 25

Why do you think a?

Answer 26

cause electorns are being lost

Answer 27

How do you know?

Answer 28

because electons are being losy

Answer 29

Hm, I agree that electrons are being lost, and they are also being gained. How do you know that Al is doing the losing and not the gaining?

Answer 30

@JoannaBlackwelder really dont kno

Answer 31

@Mehek14

Answer 32

We can tell by finding their oxidation numbers in the products and reactants. Do you know how to do that?

Answer 33

ye

Answer 34

So, what are they for Al and O on each side?

Answer 35

+3 and -1

Answer 36

@JoannaBlackwelder is b correct or not

Answer 37

e igotta go

Answer 38

cuase

Answer 39

No, b is incorrect.

Answer 40

And your oxidation are incorrect

Answer 41

*numbers

Answer 42

so c would be correct

Answer 43

yes or no before igo

Answer 44

No, you need to work on your fundamentals and not just guess.

Answer 45

so d ;)

Answer 46

I'm not going to narrow it down more for you. http://www.chemteam.info/Redox/Redox-Rules.html

Answer 47

okay but igotta go and it the last quesiton ? comeon d is correct or is another choice correct medel will be rewarded please ;_

Answer 48

;) @JoannaBlackwelder

Answer 49

I'm not just going to give you the answer. That is against openstudy policy and is generally called cheating. I gave you the info you need to find it yourself, but you are just guessing. If you want to put effort into actually understanding the problem I would be happy to help.
