The enthalpy diagram to the right represents a set of thermochemical equations. Which set of equations could it represent? A + B Right arrow. C Delta. H1 = - 500 kJ C + D Right arrow. E + 2F Delta. H2 = 100 kJ F + D Right arrow. B Delta. H3 = 200 kJ A + B Right arrow. C Delta. H1 = 800 kJ C + D Right arrow. E + 2F Delta. H2 = - 200 kJ F + D Right arrow. B Delta. H3 = - 300 kJ A + D Right arrow. E Delta. H1 = 500 kJ D Right arrow. F Delta. H2 = - 300 kJ

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

lol for the pointsss

it's c (engineer's do their work with mechanical stuff not on any living being)
