Exothermic processes: Making ice cubes,formation of snow in clouds
Endothermic processe: Melting ice cubes, evaporation of water
The reaction equation:
N₂O₅ + H₂O → 2HNO₃
Moles N₂O₅ = 0.65 / (14 x 2 + 16 x 5)
Moles N₂O₅ = 6.02 x 10⁻³
Molar ratio N₂O₅ : HNO₃ = 1 : 2
Moles HNO₃ = 2 x 6.02 x 10⁻³
Moles HNO₃ = 0.012 mole
False, because new information is being discovered all the time so they add the new information to the models to make them accurate.
