What type of reaction is baking a cake?
chemical reactionBaking a cake is a chemical reaction due to the nature of the ingredients that are mixed together and the addition of heat.
The Baking Process Carbon dioxide gas and water vapor form the bubbles which make cookies rise. Rising doesn’t just make cookies taller. It also opens up space to keep the cookie from becoming too dense. Salt slows down the decomposition of baking soda, so the bubbles don’t get too big.
