🧪 Part 1: Before the Experiment

1. What do you predict will happen when vinegar and baking soda are mixed together?

2. Which safety equipment must you wear during this experiment? (Tick all that apply)

Safety goggles

Lab aprons

Gloves

Closed shoes

3. In a combination reaction, what happens to the reactants?

They break apart into smaller pieces

They combine to form one new product

They stay exactly the same

They disappear completely

📊 Part 2: Observations During the Experiment

4. Record your observations as you conduct the experiment:

What did you see when the vinegar was added to the baking soda?

What happened to the balloon? Describe how it changed:

5. What gas was produced during this reaction?

Oxygen (O₂)

Hydrogen (H₂)

Carbon dioxide (CO₂)

Nitrogen (N₂)

6. Draw and label your experimental setup in the box below:

🔬 Part 3: Understanding the Chemical Reaction

7. Complete the word equation for this reaction:

Baking soda + Vinegar → _____________ + _____________ + _____________

8. The chemical equation for this reaction is:

NaHCO₃ + CH₃COOH → CO₂ + H₂O + CH₃COONa

Identify each component:

NaHCO₃ = _________________

CH₃COOH = _______________

CO₂ = ____________________
