N the reaction Mg + 2HCl -> MgCl2 + H2 which element’s oxidation number does not change?
BartSMP [9]

Answer:- Oxidation number of Cl does not change as it is -1 on both sides.

Explanations:- oxidation number of Mg on reactant side is 0 as it is in its elemental form(not combined with another element).

Oxidation number  of hydrogen in its compounds is +1, so if H is +1 in HCl the oxidation number of Cl is -1 as the sum has to be zero.

On product side, Mg oxidation number is +2 as the oxidation number of alkaline earth metals in their compounds is +2.

Two Cl are present in magnesium chloride, so if Mg is +2 then Cl is -1.

Oxidation number of H on product side is 0 as it is present in its elemental for, H_2 ,

So, it is only chlorine(Cl) whose oxidation number does not change for the given equation.

The possible number and location of all subatomic are one of them is electrically neutral, while the other has a stable electronic configuration.

<h3>What are subatomic particles?</h3>

Subatomic particles are those particles that are present inside the atoms. They are electron, neutron, and proton. They are charged particles, protons are positively charged, electrons are negatively charged and neutrons are neutral.

The protons and electrons totally contribute to the atomic mass of the elements.

Thus, the subatomic particles are electrically neutral and stable to electronic configurations.
