Based on the enthalpy changes given for the reactions, which reactions are endothermic? 2H20 → 2H2 + O2, AH = 484 kJ
C + 02 → CO2, AH = -394 kJ
H2 + Br2 → 2HBr, AH = -73 kJ
2NH3 + N2 + 3H2, AH = 92 kJ

Which material burns faster? metal aluminum

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)

What kind of intermolecular forces act between a hydrogen fluoride molecule and a hydrogen peroxide molecule? note: if there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.
