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

    Adding more C would shift the equilibrium to go left ward

    @taramgrant0543664 so im correct?

    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.

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

    No, we want to shift the equilibrium right.

    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.

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

    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?

    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.
