Here are the balanced equations and reaction types for your worksheet.
Part 1: Balance the reactions (1 to 9)
1. `2` NaBr + `1` Ca(OH)₂ → `1` CaBr₂ + `2` NaOH
*
Reaction Type: Double-displacement
*(The sodium and calcium switch partners.)*
2. `2` NH₃ + `1` H₂SO₄ → `1` (NH)₂SO₄
*
Reaction Type: Synthesis
*(Two things combine to make one new thing.)*
3. `1` C₅H₉O + `7` O₂ → `5` CO₂ + `4.5` H₂O
*(Note: To remove the decimal, multiply everything by 2: `2` C₅H₉O + `14` O₂ → `10` CO₂ + `9` H₂O)*
*
Reaction Type: Combustion
*(It reacts with Oxygen to make Carbon Dioxide and Water.)*
4. `3` Pb + `2` HPO₄ → `3` H₂ + `1` Pb₃(PO₄)₂
*
Reaction Type: Single-displacement
*(Lead kicks Hydrogen out of the compound.)*
5. `1` Li₃N + `3` NH₄NO₃ → `3` LiNO₃ + `1` (NH₄)₃N
*
Reaction Type: Double-displacement
*(Lithium and Ammonium switch places.)*
6. `3` HBr + `1` Al(OH)₃ → `3` H₂O + `1` AlBr₃
*
Reaction Type: Double-displacement
*(Hydrogen and Aluminum switch places.)*
7. `1` Na₃PO₄ + `3` KOH → `3` NaOH + `1` K₃PO
*
Reaction Type: Double-displacement
*(Sodium and Potassium switch places.)*
8. `1` MgCl₂ + `1` Li₂CO₃ → `1` MgCO₃ + `2` LiCl
*
Reaction Type: Double-displacement
*(Magnesium and Lithium switch places.)*
9. `1` C₈H₁₆ + `12` O₂ → `8` CO₂ + `8` H₂O
*
Reaction Type: Combustion
*(Fuel burns in Oxygen.)*
