What ions would you find in a solution if potassium perchlorate was dissolved in water?

- In aqueous solution, potassium perchlorate gives and  ions.

Explanations:- Potassium perchlorate formula is and it's an ionic compound. As per the solubility rules, all compounds of alkali metals are soluble. So,  the give ions in aqueous solution. As is clear from the formula of potassium perchlorate, it gives potassium ions and perchlorate ions when dissolved in water.

answer: mercury

explanation:

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
