im going with b !
Adding more C would shift the equilibrium to go left ward
You want which change does NOT make the equilibrium shift left
Yeah, increasing the pressure shifts the equilibrium toward less gas molecules, so no, not a.
yes Joanna has that right it would not be A
MY LAST OPTION IS C MAKES THE MOST SENSE
Removing Some of A from the system will shift the reaction to go left
No, we want to shift the equilibrium right.
so my final choice is d
Haha, yep. Cooling the system removes energy, which is a product. So it will shift right. :-)
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.
Why do you think it is b?
cause te eqation is gainign electrons
Hm, the whole reaction is gaining electrons? Why would that mean that Al is gaining electrons?
true so b is incorrect ;(
so a is correct
Why do you think a?
cause electorns are being lost
How do you know?
because electons are being losy
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?
We can tell by finding their oxidation numbers in the products and reactants. Do you know how to do that?
So, what are they for Al and O on each side?
+3 and -1
e igotta go
No, b is incorrect.
And your oxidation are incorrect
so c would be correct
yes or no before igo
No, you need to work on your fundamentals and not just guess.
so d ;)
I'm not going to narrow it down more for you. http://www.chemteam.info/Redox/Redox-Rules.html
okay but igotta go and it the last quesiton ? comeon d is correct or is another choice correct medel will be rewarded please ;_
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.
