x = 20 long tables
y = 5 round table
Explanation:
We have the following system of equations:
x + y = 25
8x + 6y = 190
From the first equation we have:
x = 25 - y
And we replace x in the second equation:
8(25 - y) + 6y = 190
200 - 8y + 6y = 190
200 - 2y = 190
200 - 190 = 2y
10 = 2y
y = 5
Now we insert the value of y in the next equation:
x = 25 - y
x = 25 - 5
x = 20

<u>Answer:</u> The number of electrons for n = 0, 1 and 2 are 2, 6 and 10 respectively.
<u>Explanation:</u>
Huckel's rule is used to determine the aromaticity in a compound. The number of delocalized
electrons are calculated by using the equation:

where,
n = 0 or any whole number
- Calculating the value of electrons for n = 0
Putting values in above equation, we get:

- Calculating the value of electrons for n = 1
Putting values in above equation, we get:

- Calculating the value of electrons for n = 2
Putting values in above equation, we get:

Hence, the number of electrons for n = 0, 1 and 2 are 2, 6 and 10 respectively.
