Background Research

>Demonstration I. Ghost And Goblins<

• Background Research : Chemical Reaction

• Principle/Concepts :

1.Exothermic Reactions:A chemical reaction that produces heat

2.Catalyst : A catalyst is a substance that increases the rate of a chemical reaction by reducing the activation energy, but which is left unchanged by the reaction.

3. Decomposition reactions: A decomposition reaction is a type of chemical reaction where one reactant yields two or more products.
