Chemistry - Chemical Equilibrium - Reversible reactions - One-Way or Two-Way?
Sort 10 reactions into IRREVERSIBLE (one-way arrow →) or REVERSIBLE (double arrow ⇌) for Grade 10-11. Irreversible: Burning wood (→ ash, can't unburn), Cooking an egg, Rusting (practically irreversible), Combustion of gasoline, Decomposition of dynamite. Reversible: N₂ + 3H₂ ⇌ 2NH₃, H₂O(l) ⇌ H₂O(g)
