An introduction to the concept of chemical reactions.
Learn how to read and interpret chemical equations.
Learn how to balance equations and get instant feedback to check understanding.
An explanation of the different types of chemical reactions.
Chemical Reactions and Stoichiometry
Control the concentrations of molecules and temperatures of reactions to explore reaction rate dynamically, and change the ratios of chemicals and observe the effects to learn how to balance chemical equations.

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also learn how to communicate what happens during a chemical reaction by writing the ratios of reactants and products, known as stoichiometry.
