Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

Explanation:

1 mole of aluminium sulfate on reaction with 3 moles of calcium hydroxide gives 3 moles of calcium sulfate and 2 moles of aluminium hydroxide.

Al2(SO4)3 + 3 Ca(OH)2 → 3CaSO4 +  2Al(OH)3

here we have 2 moles of aluminium hydroxide so that aluminium on both the side can balance.

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
