What molecule does oxygen gas bond with in the bloodstream of a human

Chemistry

When oxygen is taken into the bloodstream, the oxygen dissolves into the blood itself. The only thing is that the blood has hemoglobin and hemoglobin molecules are the ones that oxygen molecules attach to to be carried off and transported to the different parts of the body. The hemoglobin molecules contain 4 subunits which are two alpha subunits and two beta subunits. Each subunit contain iron that an oxygen molecule attaches to which makes up to 4 oxygen molecules being carried by a hemoglobin molecule. This is also the reason why oxygenated blood are brighter in color than deoxygenated blood appear to be in darker red.

A sample of 0.600 mol of a metal m reacts completely with excess fluorine to form 46.8 g of mf2. how many moles of f are in the
oksian1 [2.3K]
The balanced chemical reaction is expressed as:

M + F2 = MF2

To determine the moles of the element fluorine present in the product, we need to determine the moles of the product formed from the reaction and relate this value to the ratio of the elements in MF2. We do as follows:

moles MF2 produced = 0.600 mol M ( 1 mol MF2 / 1 mol M ) = 0.600 mol MF2
molar mass MF2 = 46.8 g MF2 / 0.6 mol MF2 = 78 g/mol
moles MF2 = 46.8 g ( 1 mol / 78 g ) = 0.6 mol
moles F = 0.6 mol MF2 ( 2 mol F / 1 mol MF2 ) = 1.2 moles F
