When two substances are combined bubbling is usually a sign of a chemical change?
Bubbling can indicate a chemical reaction is occurring because it often involves the release of gas. This gas production can be a sign that new substances are being formed, which is characteristic of a chemical change. The bubbling may be due to the release of a gas as a product of the reaction.
When a substance gives off or absorbs heat is that a sign that describes a sign of a chemical change occurring?
Yes, if a substance gives off or absorbs heat, it could be a sign that a chemical change is occurring. This process is known as an exothermic or endothermic reaction, respectively, which are common indicators of chemical reactions.
