Examples of Chemical Reactions

1. Balance the following chemical reactions. Make sure to use the correct chemical formula and the state for each substance.

a. Solid magnesium reacts with aqueous hydrochloric acid to produce aqueous magnesium chloride and hydrogen gas.

b. Aqueous sodium chloride reacts with aqueous silver (i) nitrate to produce solid silver (i) chloride and aqueous sodium nitrate.

c. Solid magnesium burns in the air to form solid magnesium oxide.

2. Observations  (make sure they are complete and descriptive):

Part 1: __________________________________

Part 2: __________________________________

Part 3: __________________________________

Part 4: __________________________________

3. For each of the reactions, what observations did you make that indicated a chemical reaction was taking place.

4. What are some clues that accompany chemical changes?

5. When balancing chemical equations what is the number you can change and what does it represent? What number can you not change and what does it represent?
