A certain metal M forms a soluble sulfate salt M2(SO4) Suppose the left half cell of a galvanic cell apparatus is filled with a 450. mM solution of M2(SO4)3 and the right half cell with a 4.50 M solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 30.0°C. Required:
a. Which electrode will be positive?
b. What voltage will the voltmeter show?

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

answer: they produce more slow than unicellular organisms.

12 is it do you think so
