Question
#1
Cu+2 + 4 NH3 <-----> Cu(NH3)4+2
The copper ion in solution is light blue. The Cu(NH3)4+2 ion is a deep blue. The tube on the left contains only copper ions. Identify what chemical was added to produce the results shown in the center tube. Identify what chemical may have been added to the center tube to produce the results shown in the right tube and write out the reaction.

The barium ion is toxic to humans. However, barium sulfate is commonly used as an image enhancer for gastrointestinal x-rays. What does this imply about the position of the equilibrium shown below.
BaSO4 <--->Ba+2 + SO4-2
#3
Hemoglobin (Hb) and oxygen gas form a complex (HbO2) that carries oxygen throughout the human body. Unfortunately, carbon monoxide also binds to hemoglobin so that an equilibrium is established. Carbon monoxide poisoning occurs when the concentration of HbO2 in the blood is reduced.
HbO2 + CO <---> HbCO + O2
The first aid for a person suffering from carbon monoxide poisoning is to (1) remove them to an area of fresh air, and (2) administer oxygen. Using the principles of equilibrium, explain how each of these helps to restore the HbO2 concentration.
Explanation / Answer
There are multiple questions here . i am allowed to answer only 1 at a time.
1.
In 1st question I dont know what tube you are using.
But I think answer will be NH3
2.
BaSO4 is precipitate.
So surely equilibrium is shifted to left
3.
1)
remove them to an area of fresh air
When we remove CO from fresh air, Concentration of CO will decrease and according to Lechatellier's principle, reaction will shift to left. that is HbCo will convert to HbO2 and CO. Thus it restores HbO2 concentration
2)
administer oxygen
When we add O2, Concentration of O2 will increase and according to Lechatellier's principle, reaction will shift to left. that is HbCo will convert to HbO2 and CO. Thus it restores HbO2 concentration
