4. Snow removal, as its snows a lot in Pennsylvania.
5. For number 5 please tell me which services the company offers & keep in mind the weather patterns are pretty hot & sunny in Florida, especially during the summers. If the company provides services (such as snow removal) Florida would hardly need any, causing the company to make less profit.
Good luck & please be sure to try your best. You got this!

Draw the lewis structure for bef2 in the box at the right, including lone pairs.
Kamila [148]

Answer :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and the unpaired electrons present in the molecule.

The given molecule is, BeF_2

Beryllium has '2' valence electrons and fluorine has '7' valence electrons. Beryllium is the central atom and fluorine is the terminal atom.

Total number valence electrons in BeF_2 = 2 + 2(7) = 16

According to the Lewis-dot structure, there are '4' number of bonding electrons and 12 number of non-bonding electrons (lone-pair).

The Lewis-dot structure is shown below.

A common anesthetic in dentistry known as nitronox consists of a mixture of dinitrogen oxide, n2o, and oxygen gas, o2, which is
Nesterboy [21]

Anesthetic in dentistry  consists of a mixture of dinitrogen oxide (N₂O) and oxygen gas (O₂), which is administered through an inhaler over the nose. Total pressure of the mixture (P_{total}) is sum of partial pressure of N₂O (p_{N_{2}O }) and partial pressure of O₂, (p_{O_{2} }).

P_{total}=p_{N_{2}O } + p_{O_{2} }

P_{total}= 740 mmHg, p_{O_{2} }=370 mmHg

So, p_{N_{2}O }= (740-370) mmHg= 370 mmHg=370 torr

Hence, partial pressure of N₂O is 370 torr.

As, 1mmHg= 1 torr.
