A 42.2 g sample of acetic acid is heated using 1043 cal. What is the change temperature of the acetic acid?

H=mc∆T

∆T = H/mc

You have the mass and Heat Energy applied

Get the specific Heat capacity of acetic acid

Plug it into the formula...You should get the answer you're looking for

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

yes
