Solution
In a chemical change, new materials form. This is because a chemical change, also known as a chemical reaction, involves a process that changes one set of chemical substances to another. While it can sometimes result in the formation of gas, an explosion, or the consumption of oxygen, these are not requirements for a chemical change. The key feature is that the original substances have been changed into different substances with different properties.
