Which of the following compounds is an Arrhenius base? Which of the following compounds is an Arrhenius base?
2 answers:
Explanation:
Arrhenius base are defined as the specie which when dissolved in water dissociate to give hydroxide ions.
For example, being an ionic compound when dissolved in water will give
and
ions.
Whereas alcohol is neutral in water under normal conditions. Hence, will not dissociate to give hydroxide ions.
On the other hand, Arrhenius acids are the species which when dissolved in water will dissociate to give hydrogen ions.
For example, and HClO will give hydrogen ions when dissolved in water.
Thus, we can conclude that out of the given options is an Arrhenius base.

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.
