The statement that best describes waves is B. Waves cannot propagate without a medium

<h3>Further explanation</h3>
Chemical changes are changes in the process that produce new substances that are different from the initial/ forming substances. Chemical changes are usually known as chemical reactions. So there are products/reactions and reactants and there is a change in the molecule/particle
The chemical reaction is usually followed by the release of heat, gas, change in color, precipitate substance etc
The heat that occurs in the addition of chemicals is caused by the reaction with water. But there is a constant rise in temperature when water reaches <em>its maximum capacity to react with these chemicals.</em>
Evidenced by the addition of 15 g and 20 g of chemicals, the temperature changes are constant
