0.0200 m fe3+ is initially mixed with 1.00 m oxalate ion, c2o42-, and they react according to the equation: fe3+(aq) + 3 c2o42-(aq) ⇄ [fe(c2o4)3]3-(aq) kc = 1.67 × 1020 what is the concentration of fe3+(aq) when equilibrium is reached? 1.67 × 1020 m 8.35 × 10-19 m 6.9a × 1021 m 1.44 × 10-22 m 0.980 am 0.940 m 0.0100 atm

explanation:

increased stability in the completion of fluorine's outer shell.

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

the answer is true. hope it .
