What type of chemical reaction is baking cookies?

When sodium bicarbonate (baking soda) heats up, it causes a chemical reaction: 2NaHCO3 ? Na2CO3 + H2O + CO2. The CO2 gas that’s formed makes the “bubbles” in the cookies. NaCl (salt) keeps the bubbles from getting too big by slowing the production of CO2.

What chemical reaction happens when you bake cookies?

While baking, the heat allows for the sucrose (sugar) to break down into glucose and fructose. This causes a polymer chain which allows for the cookie to have a light brown, shiny crust. When the sodium bicarbonate (baking soda) absorbs heat, a chemical reaction occurs – 2NaHCO3 –> Na2CO3 + H2O + CO2.
