Question

1.Which statement best explains what would happen if a reactant were added to a system in equilibrium?
O The system would shift toward the products to oppose the change.
O The system would shift toward the reactants to oppose the change.
✅ The system would shift toward the products to enhance the change
O The system would shift toward the reactant to enhance the change

2.Use the equation showing the dissociation of iron thiocyanate in water to answer the question.
FeSCN2+(aq) 2 Fe3+ (aq) + SCN-(aq)
In solution, FeSCN2+ ions are red, Fe3+ ions are pale yellow, and SCN-ions are colorless.
When a solution at equilibrium is orange, which change would cause the solution to become pale yellow?
(1 point)
O adding an ion that causes SCN- to precipitate
O adding KSCN, which dissociates into K and SCN
O adding FeCl3, which dissociates into Fe3+ and CM
✅adding an ion that causes Fe3+ to precipitate

3. Use the equation showing the dissociation of iron thiocyanate in water to answer the question.
FeSCN2(aq) 2 Fe3+ (aq) + SCN (aq)
In solution, FeSCN2+ ions are red, Fe3+ ions are pale yellow, and SCN-ions are colorless.
Given that iron ions bind with hydroxide ions to produce solid Fe(OH)3, which statement about the solution is correct?
(1 point)
O Decreasing the pH will remove Fe3+ ions and cause the solution to become more yellow.
✅Increasing the pH will release Fe3+ ions and cause the solution to become more yellow.
O Decreasing the pH will release Fe3+ ions and cause the solution to become more red.
O Increasing the pH will remove Fe3+ ions and cause the solution to become more red.

4. Use the reaction to answer the question.
3MnO42-(aq) + 4H+(aq) 2 2MnO4 (aq) + 2H2O(1) + MnO2(s)
In this reaction, MnO42-ions are green and MnO4- ions are purple.
Which substance, when added to the solution, would make the solution more purple?
(1 point)
O H2O
O MnO42-ions
✅MnO4-ions
O MnO2

5. Use the reaction to answer the question
Cr2022-(aq) + H20(1) arrows 2Cro42-(aq)+ 2H+ (aq)
Given Cr2O72-ions are orange and Cro42-ions are yellow, which change to the reaction would most effectively make the solution more orange?
(1 point)
✅ decreasing the pH
O removing water
O increasing the pH
O adding water
