A 0.20-Molar solution of K2CO3 is a better conductor of electricity than a 0.20-Molar solution of KBr. Which of the following BEST explains this observation between the two solutions. *

K2CO3 dissociates more ions than Kr

Explanation:

A solution conducts electricity because of much supply of ions an example is strong electrolytes. A solution contains both positive and negative ions and the ability of these ions to move freely allows them to carry positive and negative charges thereby conducting electricity. A solution such as K₂CO₃ dissociates more ions than KBr, therefore it is a better conductor of electricity. Neutral solutions do not conduct electricity.

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

catya that's not even a b or c
