Click here to access the interactive simulation. You will practice balancing chemical equations by playing an interactive game. After accessing the website, select the game box and start with level 1, followed by levels 2 and 3. The goal of these games is to have the same number of atoms on each side of the equation. In level 1, you balanced the equation N2 + H2 →

NH3. What number did you place in front of ammonia (NH3)?

In level 2, you balanced the equation C + H2O → CH4 +

CO2. What number did you place in front of carbon dioxide (CO2)?

In level 3, you balanced the equation NH3 + O2 → NO2 +
H2O. What number did you place in front of water?
