Evidence for Chemical Reaction

Not all chemical reactions are visible to the eye. Many chemical reactions signal their change through production of heat (exothermic reaction) – or absorption of heat (endothermic reaction). That said, visible changes often take place too. Examples of visible changes that may (not always) indicate a chemical reaction has taken place are color change, the formation of a solid, the production of bubbles, or a flame occurs. This topic provides students with a grasp of how to identify the characteristics of a chemical reaction – and to learn the information given by a chemical equation. An important skill for chemistry students is in balancing the chemical equation for a reaction.
