What are 3 indicators of a chemical reaction?
When two molecules of an element come into contact with each other, they will usually react. The two molecules will usually hit each other head on, and the energy of the collision will cause the two molecules to combine. This will usually create a new atom, or molecule, out of the two that were originally there. Another indicator of a chemical reaction is when the product of the reaction is a gas. Gas reactions are often caused by the two molecules combining to create a new atom or molecule.

What are the 6 types of chemical reactions?
The six types of chemical reactions are:1. Catalytic: This reaction occurs when two molecules of a compound work together to create a new molecule.2. Enzymatic: This reaction occurs when a molecule of a compound breaks down and releases energy.3. Anion-exchange: This reaction occurs when anions (positive charges) and electrons move from one molecule to another.4. Hydrolysis: This reaction occurs when a molecule of a compound breaks down into smaller molecules.5. Hydrolysis byproducts: This reaction occurs when a molecule of a compound breaks down into smaller molecules that have different elements in them.6. Oxidation: This reaction occurs when electrons are lost from a molecule.
