Exothermic Endothermic
⇒candle flame ⇒ cooking an egg
⇒rusting of iron ⇒ evaporation of water
⇒mixing water and ⇒ melting solid salts
strong acids
⇒H₂+1/2 O₂ → H₂O +Δ ⇒ CaCO₃ → CaO + CO₂
⇒ H₂ + N₂ → 2NH₃ + Δ ⇒ C₈H₁₈ → C₆H₁₄ + C₂H₄ [octane +Δ → hexane + ethene]
⇒ NaOH+ HCl → NaCl +H₂O ⇒N₂ + O₂ + Δ → 2NO
⇒SO₂ + O₂ → 2SO₃ + Δ ⇒ mixing water and ammonium nitrate
⇒dehydration of sugar with ⇒ photosynthesis in plant
sulfuring acid
⇒ H₂O₂ → 2H₂O+O₂ ⇒ 2CH₃CO₂H + Na₂CO₃ → 2CH₃CO₂Na +CO₂ + H₂O
ethanoic acid + sodium carbonate
→ sodium ethanoate
⇒ nuclear fission ⇒ splitting a gas molecule
