<u>Answer:</u> It determines the mass number of the atom.

<u>Explanation:</u>

Nucleons are the subatomic particles that are present in nucleus of an atom. The particles which are present in the nucleus of an atom are protons and neutrons.

Mass number is defined as the sum of number of protons and number of neutrons. It is represented as A.

A = Number of neutrons + Number of protons

Atomic number is defined as the number of protons or number of electrons that are present in an atom. It is represented as Z.

Z = Number of protons = Number of electrons

From the above information, we conclude that the number of nucleons determines the mass number of an atom.

The number of neutrons in an atom is the number of particles present in its nucleus.
The atomic number is the number of protons whereas the mass number is the number of protons and number of neutrons together
This implies that the number of neutrons is the atom's mass number

Explain. How you would separate a mixture of water, sand, salt, and iron feelings into its four component parts

Goryan [66]

Mix it. The salt will dissolve, eventually the sand and metal will settle. Pour out most of the water, let it evaporate leaving the salt. Use a magnet for the iron, which leaves the sand.

According to the chemical reac- tion, if there are 4.5 mol of oxy- genated hemoglobin present in an excess of carbon monoxide, h

Deffense [45]

A single molecule of hemoglobin can bind to 4 molecules of oxygen gas. However, hemoglobin has a greater affinity for carbon monoxide than oxygen. Therefore, an excess of carbon monoxide in the presence of oxygenated hemoglobin will result in the displacement of each oxygen atom for a carbon monoxide atom.

Hb(O2)4 (aq) + 4 CO(g) --> Hb(CO)4 (aq) + 4 O2(g)

With an excess of carbon monoxide, it is safe to assume that each oxygen molecule will be displaced with a carbon monoxide molecule. Therefore, if we have 4.5 moles of oxygenated hemoglobin (Hb(O2)4), all 4.5 moles of the species will release oxygen and bind to carbon monoxide.
