Question

I need the answer to question 2

B Endothemic, positive C Exothermic, negative D Exothenmic, positive In order to produce 972 kJ of heat, how many grams of H2 must react? 2 H2 (g) + O2 (g) → 2 H20 (g) + 243 kJ %3D A 0.250 g B 4.04 g C 8.08 g D 16.2 g 3. What can be concluded from this thermochemical equation? AH = - 45 kJ/mol r> NAOH (s) -> Na*(aq) + OH (aq) 2.
