Which of the following substances would have the greatest dispersion forces h2 o2 cl2 br2 i2 i2

-

Explanations:- All these given molecules are nonpolar as the bond is between two similar atoms. The type of dispersion forces present in non polar molecules are London dispersion forces also written as LDF.

London dispersion forces becomes stronger as the molar mass if the compound increases. In all the given molecules, the molar mass of iodine is higher and for this reason the dispersion forces are also greatest in iodine.

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
