Combination (or synthesis) - two or more elements combine to form a compound. Na + O₂ → Na₂O La2O3 + H₂0 N2O5 + H₂O ● ● ● Decomposition - a compound breaks down into elements and/or simpler compounds. KNO3 → KNO2 + O₂ NaN3 Na+ N₂ NH4NO3 → N₂O + H₂O ● ● Combustion - a fuel reacts with oxygen to release carbon dioxide, water, and heat. CH4 + O₂ CO2 + H₂O C3H8+ O₂ CO₂ + H₂O C6H12O6 + O2 → CO₂ + H₂O ● ● ● Single replacement - an element replaces another element in a compound. KCI+F₂ KF + Cl₂ Mg + HCI → MgCl₂ + H₂ Cu + AgNO3 → Cu(NO3)2 + Ag . La(OH)3 HNO3 . . Double replacement - two compounds switch parts with one another. AgNO3 + K₂SO4 → Ag₂SO4 + KNO, Ma(OH)₂ + HCI → MaCh+ H₂O .
