Answer:

D) How many valence electrons the atom contains.

This is the only closest one

An atoms reactivity can be determined by how many valence electrons the atom contains.

Answer: Option D

<u>Explanation: </u>

The tendency of elements to react with each other depends on their electronegativity. An element having higher electronegative value will react easily with other elements. So, an electronegative elements tends to have highest reactivity.

Some of the elements in the periodic table does not react with any other elements, they are the noble elements as their electronegativity values are zero. All are elements present in a single group exhibit common electronegative.

And, the measure of electronegativity is done by the number of electrons in the valence shell or in other terms the number of valence electrons. Thus, the valence electrons count decide the reactivity of an atom.

How many oxygen (O) atoms are involved in this chemical reaction?<br><br> 2Fe(OH)3 — Fe2O3 + 3H20
kenny6666 [7]

Answer:

6 oxygen atoms

Explanation:

From the equation,

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

From the reactant (left hand side) we have 2 moles of Fe(OH)₃ having (2 * 3 = 6) atoms of oxygen and decomposed to give Fe₂O₃ which contains 3 atoms of oxygen and 3 moles of water that also contains 3 atoms of oxygen.

Since the number of oxygen participating in the reaction is independent on the product (not a reversible reaction) then the total number of oxygen atoms participating in the reaction is 6

sp2606 [1]

Answer:

1. Removing them to an area of fresh air. This helps to prevents further poisoning by the carbon monoxide and increase the amount of oxygen entering into the body. This will help to reduce the concentration of carbon monoxide binding oxygen

2. Administering pure oxygen goes a long way to enhance ventilation and increase the oxygen saturation to 100%. This will help to overcome the effect of the carbon monoxide and promote more hemoglobin binding
