Besides water, what is the product of a Neutalization Reaction between Mg(OH)2 and H3PO4?

a. Mg3(PO4)2
b. Mg-3(PO4)+2
C. (PO4)2Mg3
d. MgPO

The answer to your question is letter A

Explanation:

Data

Reactants   Mg(OH)₂ and H₃PO₄

This is a neutralization reaction because the reactants are a base (Mg(OH)₂) and an acid (H₃PO₄).

The products in a neutralization reaction are always water and a salt.

Balanced chemical reaction

         3Mg(OH)₂ + 2H₃PO₄  ⇒ Mg₃(PO₄)₂ + 6H₂O

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
