CENTURY has a whole host of different media so you can choose how to learn, depending on what you enjoy most! The teachers at CENTURY create learning videos for different nuggets, to take students through the course in an engaging and interactive way.

Here is a recap of Percentage Yield and Atom Economy:

 

In this video, we answer:
How to calculate the percentage yield of a reaction product from the actual yield of a reaction?
How to calculate the theoretical amount of a product from a given amount of reactant?
How to calculate the atom economy of a reaction to form a certain product, from the balanced chemical equation?
We explain why a particular reaction pathway is chosen to produce a specified product given appropriate data such as atom economy (if not calculated), yield, rate, equilibrium position and usefulness of by-products.
