Directions:
1. Start Internet Explorer go to Classic Chembalancer.
2. Click ‘Directions’. Read and understand the directions.
3. Click ‘OK’.
4. Click on ‘Start Game’
5. Try entering some numbers in the text boxes in front of each molecule. What happens?
6. If you forget the directions, click on the ‘How to Play the Game’ link. Click ‘OK’ when you finish reading them to return to the game.
7. When you think you have typed the right numbers in all the boxes, click the ‘Balanced’ button.

10. Repeat steps 7-9 for the other 10 questions.
11. Now do the two problems on the back of this worksheet. You can draw the molecules just like the program did to figure out the answer.
Fill in the blanks below as you go though the game. This is so I have a record that you did your assignment.
1. _____ Fe +
_____ S --> _____
2. _____ H2 + _____ Cl2 --> _____ HCl
3. _____ Mg + _____ O2 --> _____ MgO
4. _____ O2 + _____ H2 --> _____ H2O
5. _____ HgO --> _____ Hg + _____ O2
6. _____ Ca + _____
H2O -->
_____ Ca(OH)2 +
_____ H2
7. _____ CH4 + _____ O2 --> _____ CO2 + _____ H20
8. _____ Na2O2 + _____ H2SO4 --> _____ Na2SO4 + _____ H2O2
9. _____ N2 + _____ H2 --> _____ NH3
10. _____ Al + _____ O2 --> _____ Al2O3
11. _____ KMnO4 --> _____ K2O + _____ MnO + _____ O2
Draw the molecules just like the program did to figure out the answer to #12 and #13.
12. _____ Na + _____ H2O --> _____ NaOH + _____ H2
Fact for #12: Sodium metal, Na, is stored in kerosene so
it won
13. _____ H2SO4 + _____ NaOH --> Na2SO4 + _____ H2O
Fact
for #13: This is an example of an acid base reaction. Acid + base --> Salt + Water
