Chemical A and Chemical B react in an exothermic reaction. What can be known about what (1 point) will happen when Chemical A and Chemical B are mixed together?
O The new substance will need more energy to form its chemical bonds than the old substance will release.
More energy will be released from the old substance than the new substance will need to form its chemical bonds.
The color will change as a result of the reaction.
The substance will bubble as a result of the reaction.

B

Explanation:

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

diaria maybe go see a doctor about that
