Q2: High pressure (2-5 atm) is applied to increase the solubility of CO2 in soda. When a can of
soda is open, the pressure drops to 1 atm. If you leave the can open for a long time, the soda
will taste flat. How can you explain this in terms of solubility and pressure?
When can of an open pressure decreases, so
solubility decreses.

Ответ:
The correct answer is Option D.
Explanation:
Lewis dot structures are the structures which represent the valance electrons of an element forming a compound. The electrons are represented as the dots.
In a compound, the bonded electrons are represented as a bond and lone pair of electrons are represented as dots.
In
compound,
Electronic configuration of Nitrogen:
Valence electrons in nitrogen = 5
Electronic configuration of hydrogen:
Valence electrons in hydrogen = 1
In the given compound, bond pairs are 2 which means number of electrons bonded are 4.
Unbonded electrons left on nitrogen will be 3 and this compound has an extra electron because of the negative charge present on the compound. Hence, total unbonded electrons present on this compound will be 4.
Therefore, the lewis dot structure will be Option D.
