TLF ID L2573
Investigate chemical reactions at a molecular level. Examine collisions between molecules of two reactants. Adjust the ratios of the reactants and compare the outcomes. Identify the number of molecules involved in a balanced reaction. For example, two A molecules combine with a B2 molecule to form a molecule of A2B2. This learning object is one in a series of six objects. The series is also packaged as a combined learning object.
