The enthalpy diagram to the right represents a set
of thermochemical equations. Which set of
equations could it represent?
A+BCAH = - 500 kJ
C + D →E + 2F AH2 = 100 kJ
F+D →BAH3 = 200 kJ
CA+B →CAH = 800 kJ
C + D + E + 2F AH2 = - 200 kJ
F+D+BAH3 = - 300 kJ
A+DE AH = 500 kJ
DF AH2 = - 300 kJ
E +F
AH

A + 2D
(Arrow lengths are not to scale.)

A + B  C   H1 = 800 kJ

C + D  E + 2F   H2 = - 200 kJ

F + D  B   H3 = - 300 kJ

Explanation:

Just answered it correctly on EDGE

Option B

---> 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

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
