Polarity is important because polar and nonpolar molecules have different properties. Polar molecules interact(___?) with other polar molecules but(__?) interact with nonpolar molecules, and vice versa. a) Strongly
b) do
c) do not
d) weakly

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

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

that tool would be a compass
