Please help asap 11) Calculate the wavelength of light emitted when each of the following transitions occurs in the hydrogen atom.

a) n = 3 -> n=2

b) n = 4 -> n=2

c) n = 2 -> n = 1

12) Using vertical lines indicate the transitions from question 11 on an energy level diagram for the hydrogen atom.

your answer would be a. 12.5 kg

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 should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
