Now I just need 3 and 4 checked
What mass of water is produced by the complete combustion of 12.6 moles of prepene C3H6. C3H6 + O2 --> H20 + CO2
Your answers look mostly correct! Here are the correct predictions for each question:
1. (a) adding Br2 - It shifts to the right.
(b) removing Br2 - It shifts to the left.
(c) removing NO - It shifts to the right.
2. (a) adding O2 - There is no effect.
(b) removing KCl - It shifts to the right.
(c) removing O2 - It shifts to the left.
(d) removing KClO3 - It shifts to the right.
3. (a) increasing the reaction temperature - It shifts to the right.
(b) decreasing the reaction temperature - It shifts to the left.
4. (a) increasing the reaction temperature - It shifts to the right.
(b) decreasing the reaction temperature - It shifts to the left.
Your answers were mostly correct, but there were a few predictions that were incorrect. Keep in mind that when analyzing the effect of changes on equilibrium, it's important to consider Le Chatelier's principle.
Here are the answers to the questions you provided:
1. (a) adding Br2: The reaction shifts to the right. When more Br2 is added, according to Le Chatelier's principle, the system will try to counteract the increase in Br2 concentration by favoring the forward reaction to consume the additional Br2.
(b) removing Br2: The reaction shifts to the left. If Br2 is removed, the system will try to compensate for the loss by favoring the reverse reaction to produce more Br2.
(c) removing NO: The reaction shifts to the right. When NO is removed, the system will respond by favoring the forward reaction to produce more NO.
2. (a) adding O2: The reaction shifts to the right. Adding O2 will increase the concentration of oxygen, and in response, the system will favor the forward reaction to consume the additional O2.
(b) removing KCl: The reaction shifts to the right. Removing KCl will disrupt the equilibrium, and the system will try to restore it by favoring the forward reaction to replace the lost KCl.
(c) removing O2: The reaction shifts to the left. If O2 is removed, the system will adjust by favoring the reverse reaction to replenish the lost O2.
(d) removing KClO3: The reaction shifts to the left. When KClO3 is removed, the system will respond by favoring the reverse reaction to replenish the lost KClO3.
3. (a) increasing the reaction temperature: The reaction shifts to the right. Since the reaction is endothermic, increasing the temperature favors the endothermic direction to absorb the additional heat.
(b) decreasing the reaction temperature: The reaction shifts to the left. With a decrease in temperature, the system will try to maintain equilibrium by favoring the exothermic direction to generate more heat.
For the last question, you have given the reaction but not the specific changes. Please provide the changes so I can assist you further.
