The following reaction shows the products when sulfuric acid and aluminum hydroxide react.
2Al(OH)3 + 3H2SO4 - Al2(SO4)3 + 6H20
The table shows the calculated amounts of reactants and products when the reaction
was conducted in a laboratory.
What is the approximate amount of the leftover reactant?

h let me think

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

it is the most commonly accepted one
