1. Chemical Reaction - process of one or more substances combining
and converting to form new substances with different properties
2. Reactants are mixed together (react) chemically to form a
new product or products.
3. Based on class observations and activities, fill out the chart below:
4. Conservation of Mass states that mass cannot be lost or gained
in a chemical reaction; the number of atoms are the same before
and after the reaction.
5. A balanced chemical equation illustrates the Conservation
of Mass.
6. Rust is a reaction between Iron and Oxygen.
7. Chemical Reactions can cause substances to either combine
into a new substance or separate into multiple substances.
8. Exothermic Reaction - a reaction in which heat is released
9. Give an example of an Exothermic Reaction. _______________________________________
10. Endothermic Reaction - a reaction that get cold because
Energy is being absorbed while reacting.
11. Give an example of an Endothermic Reaction. _____________________________________
12. An increase in temperature, surface area, and/or concentration
increases reaction rate.
13. A catalyst increases reaction rate but does not undergo
a permanent chemical change itself.
