using the symbol M for the element, write the chemical formula for the compound that forms when element M reacts with iodine.

Anon25 [30]

Answer : The chemical formula for the compound is, $MI$

Explanation :

When the element 'M' react with the $I_2$ to give $MI$ .

The balanced chemical reaction is,

$2M+I_2\rightarrow 2MI$

In this reaction, 'M' is in mono-atomic form and $I_2$ is in diatomic form.

By the stoichiometry,

2 moles 'M' react with the 1 mole of $I_2$ to give 2 moles of $MI$ .

Therefore, the chemical formula of the compound is, $MI$

If a red blood cell is 100% saturated, how many molecules of O2 are bound to it?1 billion molecules of O24 molecules of O2250 mi

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:

$\frac{270 \cdot10^{6} hemoglobine molecules}{1 red blood cell} \cdot \frac{4 heme group}{1 hemoglobine molecule} \cdot \frac{1 O_{2} molecules}{1 heme group} = 1 \cdot 10^{9} O_{2} \frac{molecules}{red blood cell}$
