First page is completed as shown. I need help with the bottom o the second page on. Please put the part (part A, B, C, D) so I know which answer is for which part.

Hi, can someone help me answer these questions? I promise to rate you!!

1. In Le Chatlier's principle, can you describe the reaction between Fe+3 and SCN- with Fe(SCN)+2. The reaction turned reddish brown when Fe+3 and SCN- were mixed together. Where does the equilibrium shift?

2. In Le Chatlier's principle, can you describe the reaction when 0.1 M Ni(NO3)2 and 6 M of NH3 are mixed together. The color changed from light blue to dark blue. After that we added 6 M HCl, the color changed again to a lighter color. Where does the equilibrium shift?

3. In Le Chatlier's prinicple, can you describe the precipitation that occured when NaOH and Ca(NO3)2 were mixed together? Also, after being centrifuged, the solution and the precipitation solid (white) separated. We threw out the liquid and added HCl and NaOH. Where does the equilibrium shift?

4. In Le Chatlier's prinicple, can you describe the reaction that occured when 5 drops of 0.1 M Co(NO3) is added mixed with 5 drops of concentrated HCl. The color changed into pink. When we added water, the color changed into light pink. Then when we boiled it, it turned blue. After cooling, it turned pink again. Where does the equilibrium shift?

5. We took two test tubes, marking one ACID and one is BASE. We added 3 mL of H2O in each. We added 6 drops of 6 M HCl to the acid tubes and a drop of NaOH to the base tube. Then we added 4 drops of the indicator on each (methyl orange- indicator). The acid tube turned into color pink after the indicator and NaOH again was added. The base tube turned yellow after the indicator and HCl solution is added. In Le, Chatlier's principle, can you describe this whole reaction? Where does the equilibrium shifts?

THANK YOU SO MUCH. I KNOW IT'S A LOT, BUT I PROMISE TO RATE YOU!!!

5)When colorless K2CO3 solution is mixed with colorless HCl solution, what will happen?

A)Color change

Nothing

Bubbling

D)	Precipitation

6)In Vinegar Analysis lab, the end point is reached when the final drop of NaOH makes the mixture basic, which turn the pH indicator pink. However, if we put the flask on the bench long enough, the pink color may eventually disappear due to some substance from the air. What substance from air is causing the pink color of pH indicator to disappear?

A)CO2 to neutralize the small amount of NaOH

B)N2
