What are the chemical reactions in baking a cake?
Baking powder, which is baking soda with an additional acidic salt, releases carbon dioxide twice during the baking process, once when it hits water, and again when it reaches a certain temperature in the oven. Heat helps baking powder produce tiny bubbles of carbon dioxide, which make a cake light and fluffy.
Why is cooking a chemical change?
Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. An unexpected color change or release of odor also often indicates a chemical change.
Why is baking bread an example of a chemical change?
Why is baking bread and example of a chemical change? Heating up the bread causes the dough to rise because of the heat. This is a chemical change because it is a transition from Mercury Oxide to Mercury and Oxygen.
Is baking a cake fast or slow reaction?
