Answer :

(1) The number of valence electrons present in the compound is, 20

(2) The number of bonded electrons present in the compound is, 4

(3) The number of lone pair electrons present in the compound is, 16

(4) The number of single bonds present in the compound is, 2

Explanation :

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

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, OF_2

As we know that oxygen has '6' valence electrons and fluorine has '7' valence electrons.

Therefore, the total number of valence electrons in OF_2 = 6 + 2(7) = 20

According to Lewis-dot structure, there are 4 number of bonding electrons and 16 number of non-bonding electrons or lone pair of electrons.

The Lewis-dot structure of OF_2 is shown below.

A particular 3.0 L solution contains 2.5 mmol (millimoles) of a substance. What is the concentration of this solution in number
bearhunter [10]

Answer: 0.83mol/m3

Explanation:

Number of mole = 2.5 mmol = 0.0025mol

Recall

1L = 0.001m3

Therefore 3L = 3x0.001 = 0.003m3

0.003m3 contains 0.0025mol

Therefore, 1m3 will contain = 0.0025/0.003 = 0.83mol

The concentration in mol/m3 is 0.83mol/m3

A car traveling at a constant speed travels 175 miles in four hours. How many minutes will it take for the car to travel 1000 fe
elena-14-01-66 [18.8K]

It takes 0.26 minutes to travel 1000 feet

<u>Solution:</u>

Given that car traveling at a constant speed travels 175 miles in four hours

Distance = 175 miles

Time taken = 4 hours

Convert the units to feet and minute

Given that,

1 mile = 5280 feet

175 miles = 5280 x 175 feet = 918720 feet

Also we know that,

1 hour = 60 minutes

4 hours = 60 x 4 minutes = 240 minutes

Thus, we got,

Distance = 918720 feet

Time taken = 240 minutes

<em><u>Find the speed of car</u></em>

<em><u>Speed is given by formula:</u></em>

speed = \frac{distance}{time}

speed = \frac{918720}{240} = 3828

Thus speed of car is 3828 feet per minute

<em><u>How many minutes will it take for the car to travel 1000 feet?</u></em>

Let "x" be the minutes needed for 1000 feet

speed of car is 3828 feet per minute

1 minute = 3828 feet

x minute = 1000 feet

This forms a proportion. We can solve by cross multiplying

x \times 3828 = 1000 \times 1\\\\x = \frac{1000}{3828}\\\\x = 0.26

Thus it takes 0.26 minutes to travel 1000 feet
