SO₄²⁻  +NH₃  →   SO₃²⁻ + H₂O  +N₂

The  balanced  of  the above  redox reaction   is as below

3SO₄²⁻ + 2NH₃   →  3SO₃²⁻  + 3 H₂O  + N₂


 Explanation

According   to the law of mass conservation the  number  of atoms  in the reactant side  must  be equal to number of atoms in product side.

Inserting coefficient 3 in front of SO₄² , 2  in front  of NH₃, 3 in front  of SO₃²⁻  and 3 in front  of H₂O balance the equation above. This  is  because  the number  of atoms  are equal in both side.

for example there are 2 atoms of N in both side of the reaction.

Equivalent reaction equation :

3SO₄²⁻ + 2NH₃ ---> 3SO₃²⁻ + N₂ + 3H₂O

<h3>Further explanation</h3>

In equalizing the redox reaction we can use the oxidation number method or half the reaction of the ions

Oxidation number method  :

1. Determine the reducing agent and oxidizing agent

2. Equate the element that experiences a redox reaction

3. Determine the amount of reduction / increase in oxidation number (number of atoms x change in oxidation number)

4. Equate the number of changes in the oxidation number by giving a coefficient

5. equal charge (H + for acidic situations and OH- for alkaline conditions)

6. Balance the H atom with the addition of H₂O

From the reaction :

SO₄²⁻ + NH₃ ---> SO₃²⁻ + H₂O + N₂

1. SO₄²⁻  ---> SO₃²⁻ = reduction (for S : +6 to +4)

NH₃ --->  N₂ = oksidation (for N : -3 to 0)

2. add coefficient  to equate atom N

SO₄²⁻ + 2NH₃ ---> SO₃²⁻ + N₂

3. SO₄²⁻ + 2NH₃ ---> SO₃²⁻ + N₂

  |_+6___2 x 3__+4_|

                  |_-6____6 x 1___0_|

4. giving a coefficient

3SO₄²⁻ + 2NH₃ ---> 3SO₃²⁻ + N₂

5. charge already the same (left = -6, right = -6)

6. Balance the H atom with the addition of H₂O

3SO₄²⁻ + 2NH₃ ---> 3SO₃²⁻ + N₂ + 3H₂O ----> Balance

A molecular orbital that decreases the electron density between two nuclei is said to be ____.
nikklg [1K]

A molecular orbital that decreases the electron density between two nuclei is said to be <u>antibonding.</u>

The bonding orbital, which would be more stable and encourages the bonding of the two H atoms into H_{2}, is the orbital that is located in a less energetic state than just the electron shells of the separate atoms. The antibonding orbital, which has higher energy but is less stable, resists bonding when it is occupied.

An asterisk (sigma*) is placed next to the corresponding kind of molecular orbital to indicate an antibonding orbital. The antibonding orbital known as * would be connected to sigma orbitals, as well as antibonding pi orbitals are known as \pi* orbitals.

Therefore,  molecular orbital that decreases the electron density between two nuclei is said to be <u>antibonding.</u>

<u></u>

Hence, the correct answer will be option (b)
