How does baking a cookie demonstrate a combination reaction?

[Figure1]

There are a total of 6 types of reactions: combustion, synthesis, decomposition, single displacement, double displacement, and acid-base. What type of reaction is demostrated by baking a cookie?  

To make a chocolate chip cookie, you need butter, sugar, flour, oil, and chocolate chips. Next combine the ingredients, mix them together, arrange on a cookie sheet, and bake. Within 15 minutes, you'll have yourself some mouthwatering treats!

Creative Applications

  1. What is the reaction called when you add all of the ingredients together to get the final product, cookies?
  2. Similar to how when you mix many ingredients, what happens in a chemical reaction when you add together two elements such as calcium and sulfur?
  3. What would the end product be called? (Hint- combine element names)
  4. What makes this process more complicated than just a combination reaction?

This is an easy model that you can look back to when trying to analyze reactions. Because baking involves other types of processes than just a combination reaction, this is just a simple example that doesn’t include anything about the reactions that take place with certain ingredients like baking powder.
