The shape of the sulfur dioxide molecule, where sulfur is the central atom is
fgiga [73]

Answer:

bent

Explanation:

The molecular formula of sulfur dioxide is written as SO₂

The molecular geometry of sulfur dioxide can be determined using the Lewis structure.

The Lewis structure shows the distribution of electrons around the atoms of a given compound such as sulfur dioxide (SO₂).

In this compound, sulfur is the central atom with 6 valence electrons.

The sulfur is bonded covalently with two oxygen atoms, each with 6 valence electrons. Oxygen contributes 2 lone pairs while sulfur which is the central atom contributes 1 lone pair of electrons in the bond.

The bond angle between the two oxygen atoms and the central sulfur atom is approximately 120⁰, as a result of the bent shape of the molecular structure.

Answer:

5. +5

6. +7

Explanation:

The oxidation state can be obtained as follow:

5. Oxidation state of oxygen, O = –2

Oxidation state of phosphorus, P =?

P3O10 = –5

3P + 10O = –5

3P + (10 x –2) = –5

3P – 20 = –5

Collect like terms

3P = –5 + 20

3P = 15

Divide both side by 3

P = 15/3

P = +5

Therefore, the oxidation state of P in P3O10^5- is +5

6. Oxidation state of oxygen, O = –2

Oxidation state of manganese, Mn =.?

Mn2O7 = 0

2Mn + 7O = 0

2Mn + (7 x –2) = 0

2Mn – 14 = 0

Collect like terms

2Mn = 14

Divide both side by 2

Mn = 14/2

Mn = +7

Therefore, the oxidation state of Mn in Mn2O7 is +7
