2. Qualitative vs. Quantitative Qualitative shows the reactants you need to make a product. Quantitative shows you the number of each part needed for the product.

3. Examples: Cheeseburger: Meat Patty + Bun + Cheese + Pickle = Cheeseburger (reactants) (product) M + B + C + P → MB₂CP₃ (Unbalanced) M+2B+C+3P → MB₂CP₃ (Balanced)

4. + → Try balancing this…. Recipe for a glass of lemonade: four bottles of water and three lemons. Answer: 4B + 3L → B₄L₃

5. Think of your own everyday item and write a qualitative equation (word description).

6. + + →

7. Skate Board Answer: Trucks + Wheels + Deck → Skate Board T + W + D → T₂W₄D 2T + 4W + D → T₂W₄D

8. Ice cream cone: Ice cream scoops + Cone + Cherry + Sprinkles → Ice cream cone Ic + C + Ch + S → Ic₃CChS₁₀ (Unbalanced) 3Ic + C + Ch + 10S → Ic₃CChS₁₀ (Balanced)

9. Supplemental Facts: Defender + Midfielders + Attacker + Goalkeeper → soccer team D + M + A + G → D₄M₃A₃G (Unbalanced) 4D + 3M + 3A + G → D₄M₃A₃G (Balanced)
