Objectives
The unit will be taught over a four week period at the beginning of the year. Prior to the unit, the following items will have already been covered:
- The 12 principles of Green Chemistry - What are they, and what do they mean? Let's talk about sustainability.
- The Periodic Table - How to read and interpret atoms, protons, electrons, neutrons, and charges.
- Reactions - Reactants, and products makeup reactions. There are 6 main types of reactions.
The Unit will teach the following objectives:
- Multiple Step Reactions - Everyday products that we use are usually synthesized with multiple step reactions.
- Reaction Types - The reaction types generally fall into 6 categories (Table A).
- Basic Stoichiometric Dimensional Analysis - This methodology (often called stoichiometry) allows amounts and units to be converted based on commonalities.
- Law of Conservation of Mass - Mass in neither created nor destroyed. The mass of the reactants must always equal to the mass of the products.
- Atom Economy - This is the determination of the efficiency (at an atomic level) of the product being created.
- E-Factor - This is the environmental factor that calculates the amount of waste by the amount of product created. It gives an overall ratio as to the impact that a product can have.
- Case Study - Ibuprofen will be used as a case study to determine how multiple step processes were optimized to increase atom economy and yield.
