Predicting Products for Decomposition Reaction: Carbonates (CO2): When heated, it decomposes into carbon dioxide (CO₂) and an oxide (0²). Example: Calcium Carbonate (CaCO3) Carbon Dioxide (CO₂) +Calcium Oxide (Cao) Predict the product/s: CaCO3 → CO₂ + CaO Balanced equation: 1CaCO3 1CO₂ + 1CaO /www.laurel.kyschools.us/userfiles/1012/Classes/65686/5.pdf?id-69487 Do This: 1. Magnesium Carbonate (MgCO3)→ Carbon Dioxide (CO₂)+Magnesium Oxide (MgO) Predict the product/s: MgCO3 → Balanced equation: 2. Aluminum Carbonate (Al2(CO3)3) Carbon Dioxide (CO₂) +Aluminum Oxide (Al₂O3) Predict the product/s: Al2(CO3)3 → Balanced equation: • Hydroxides (OH-1): When heated, it decomposes into water (H₂O) and an oxide(02-). Example: Sodium Hydroxide (NaOH) Water (H₂O) + Sodium Oxide (Na₂O) H₂O + Na₂0 Predict the product/s: NaOH Balanced equation: 2NaOH →>> Source:https://www.laurel.kyschools.us/userfiles/1012/Classes/65686/5.pdf?id-69487 1H₂O+1Na₂O Do This 3. Aluminum Hydroxide (Al(OH)3)→ Water (H₂O) + Aluminum Oxide (Al2O3) Predict the product/s: Al(OH)3 →→ Balanced equation: Guide Questions. 4. How many reactant/s are there in a decomposition reaction? How many substance/s is/are formed in a decomposition reaction? 5. 6. What happened to the reactant in a decomposition reaction? 7. What is added to the reactant in order to decompose? Precipitation reaction - a reaction where two solutions are mixed forming an insoluble product known as precipitate. Example: Barium chloride reacts with sodium sulfate forming barium sulfate and sodium chloride BaCl₂ + Na₂SO4 →BaSO, + NaCl BaSO4 + 2NaCl Balanced equation: BaCl₂ + Na₂SO4 Do this: 8. Predict the product/s: KC1+ Pb (NO3)2 Balanced equation: 9. Predict the product/s: NH,C1 + AIPO4 → Balanced equation: Acid-base Neutralization - a reaction where an acid and a base reacts with one another forming salt and water. Acid + Base Salt + Water Example: The reaction between hydrochloric acid and sodium hydroxide will yield to sodium chloride and water. HCl + NaOH HCl + NaOH Balanced equation: Do this: 10. Predict the product/s: 11. Balanced equation: 12. Predict the product/s: 13.Balanced equation: NaCl + H₂O → NaCl + H₂O HF + Ca(OH)2 HNO3 + NH4OH →→→→
