Combustion & Types of Chemical Reactions 🔥⚛️

📅 Lesson Overview:
Today, we completed part of the notes on combustion and types of chemical reactions while also finishing the Endothermic & Exothermic Reactions Lab Post-Lab, which was due today.

📝 What We Covered:

1️⃣ Post-Lab Work (First 20 Minutes)

• Reviewed temperature changes and observations from the Endothermic & Exothermic Reactions Lab.

• Completed and submitted the post-lab analysis.

2️⃣ Introduction to Combustion Reactions

• What is Combustion?

  • A chemical reaction that releases energy by burning fuel in the presence of oxygen.

  • Produces carbon dioxide (CO₂), water (H₂O), and energy (heat/light).

• Examples of Combustion:

  • Burning wood in a campfire.

  • Gasoline combustion in a car engine.

  • Cellular respiration in the human body (how we get energy from food!).

🌍 Why This Matters:

Understanding combustion reactions helps explain how cars run, fires burn, and our bodies produce energy! Recognizing different reaction types is key to predicting how substances interact in chemistry.

✅ Great job today! Be ready to finish the Types of Reactions notes in the next class!
