I haven't slept in 2 days and am so exhausted. Please if anyone could help... I have class in 2 hours and it's 3am rn

Solution:-

Now

#1

Let's look at the EC of carbon(Z=6)

Now.

3 electrons are shared(1 with H_3C and 2 with N+)

Hence

Electron left unshared=4-3=1

#2

Lets look at EC of Nitrogen(N),Z=7

But

Its Cation i.e N+

Hence

Electron left unshared=4-3=1

#3

Lets look at EC of Oxygen(Z=8)

But it is anion hence 1electron required more which us bonded

Hence

Number of electrons left unshared=0

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

it is the most commonly accepted one
