Final T = 24.650 Endothermic = SUMMARY

Is this correct? Do I divide by 2 and how do I determine what I divide by?

Answer 1

20 & 24 Caty a is for ined, Here nothing is one mole of multiplied as product divided. So AH AH = (.42x300x 15+ 4.18x5950x-5) I AHAH = 13.0655 kJ a s mole of H₂ is it is mole of c used, so altas 4 st At = 52.26 kJ I mol remb remember for each time calculating Alf are mole of product is to be formed. and Th < T; endothermic.
