2. What Exactly are Chemical Reactions?
A change in which a substance is changed into one or more new substances.

3. Why do Such Reactions Occur?
So that way atoms can gain stability. Oxygen will react with carbon because the product, carbon dioxide, has more stability.

4. What is a Chemical Equation? Why do we use them?
A chemical equation is an easy and useful way of describing a change, particularly what is present before and after said change.
We use them to summarize easily what events occur.

5. Should They be Balanced?
Equations should always be balanced as to show that mass is conserved. *Remember the Law of Conservation of Mass*

6. Reactants and Products?
Reactant--- Any substance that undergoes a chemical change in a given reaction.
Product--- A substance obtained from another substance through chemical change.

7. What IS That Funny Little Jigger?
Carbon + Oxygen Carbon Dioxide
That arrow is showing the transition from the substances being separated to the substances undergoing a reaction and turning into another substance.

8. Synthesis Reactions A + B AB
A reaction when there is a combination of two or more substances and a compound results.
C + O CO2
A + B AB

9. Decomposition Reactions
The opposite of synthesis. It is when a compound is broken down into simpler substances.
CO C + O
AB A + B

10. Single Displacement Reaction
A metal replaces a metal, or a nonmetal replaces a nonmetal.
H + CO H2O + C
A + BC C + AB

11. Double Displacement Reaction
A metal replaces a metal, and a nonmetal replaces a nonmetal, except this time there are two being replaced.
Ba2F + Zn2Cl Ba2Cl + Zn2F
AB + XY AY + XB
