Try the new HTML5 Balancing Chemical Equations simulation! How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas. Students will learn to:

• Balance a chemical equation.
• Recognize that the number of atoms of each element is conserved in a chemical reaction.
• Describe the difference between coefficients and subscripts in a chemical equation.
• Translate from symbolic to molecular representations of matter.

Thank you American Association of Chemistry Teachers for your generous donation that supported the development of the new HTML5 Balancing Chemical Equations.
