Short explanation
Apply conservation of energy to explain that energy cannot be created or destroyed during a chemical reaction is best revised by linking the named science to Universal chemistry ideas, then checking it against examples from Key ideas in chemistry. Approved keywords include cannot, apply, conservation, and energy. conservation of energy is useful here because the principle that energy cannot be created or destroyed, only transformed from one form to another. Avoid students often think that energy can be created or destroyed during a chemical reaction; instead emphasize that energy is conserved in chemical reactions, meaning it can only change forms but cannot be created or destroyed. Remember to always remember that energy cannot be created or destroyed in a chemical reaction; it can only change forms. Link your answer to Universal chemistry ideas in Key ideas in chemistry, and keep the biology specific to cannot. This understanding helps you explain reaction processes accurately and apply the concept of energy conservation in various contexts. This keeps revision aligned with the approved learning objective on apply conservation of energy to explain that energy cannot be created or destroyed during a chemical reaction.
