Answer:
Explanation:
Hello!
In this case, since the equilibrium expression for the considered equation is:
Which can be written in terms of the reaction extent and the ICE chart and the initial concentrations of 0.453 M as shown below:
We can solve for x as follows:
In such a way, we obtain the following concentrations at equilibrium:

Answer:
1 billion molecules O₂
Explanation:
From my research, a human red blood cell contains approximately 270 million hemoglobin molecules.
A hemoglobin molecule contains four heme groups, <em>each of which has an iron ion forming a coordination complex that carries every dioxygen molecule. </em>Therefore for each hemoglobin molecule, we will have 4 dioxygen molecules. The heme groups are responsible for the transport of every dioxygen and other diatomic gases.
Hence, the number of O₂ molecules in a red blood cell saturated with 100% will be:
So, the correct answer is 1 billion of O₂ molecules.
Have a nice day!
