CHEMISTRY
Material Balancing
(AOCMB)
Formats: Interactive Web, CD-ROM
O V E R V I E W
This interactive training unit is designed to familiarize trainees with basic concepts associated with using balanced chemical equations to calculate the amounts of reactants and products in process reactions. After completing this unit, trainees should be able to explain what material balancing is, verify that a chemical equation is balanced, and use a balanced equation to calculate the amounts of reactants and products in a reaction when the weight of one reactant is given. They should also be able to identify two basic factors that can limit the production of a process system, perform material balancing for a process system when reactant supply is the limiting factor, and perform material balancing for a system in which a specific amount of product is to be produced.
