Draw a Lewis structure for O3 in which the central O atom obeys the octet rule, and answer the following questions based on your
drawing. The number of unshared pairs (lone pairs) on the central O atom is: The central O atom forms single bonds. The central O atom forms double bonds.
1 answer:
Answer:
The unpaired electron pair on central atom = 1
The central atom form 1 single bond 1 double bond with oxygen atoms.
Explanation:
Ozone,
Valence electrons of oxygen = 6
Only the valence electrons are shown by dots in the Lewis structure.
The Lewis structure is shown in the image below.
From the Lewis structure, it can be concluded that:-
The unpaired electron pair on central atom = 1
The central atom form 1 single bond 1 double bond with oxygen atoms.

Here's what I get
Explanation:
1. Sugar
(a) Dissolving in water
The white solid dissolves in water to give a colourless solution. There is no evidence that a new substance is being produced.
(b) Addition of sodium hydroxide
Adding the colourless solution of sodium hydroxide to the colourless sugar solution gives a colourless solution. There is no evidence that a new substance is being produced.
2. Magnesium sulfate
(a) Dissolving in water
The colourless crystals dissolve in water to give a colourless solution. There is no evidence that a new substance is being produced.
(b) Addition of sodium hydroxide
Adding the colourless solution of sodium hydroxide to the colourless solution of magnesium sulfate gives a white precipitate (see image). This is evidence that a new substance is being produced.
