A qualitative understanding of reactions is great. But how much reactant do I need in order to generate the amount of product that I want?
(November 2017) Stoichiometry is simply the ratios of reactants and products in the balanced reaction. But those ratios can be extended to include very complex multi-step chemical conversions to answer very practical quantitative problems.
As you can see from this podcast, the mastery of some very important concepts and practices come into complete focus in this podcast, including, scientific number and notation, significant figures, conversions, density, stable molecular formulas and compounds, balancing reactions, molar mass and molecular weights, and moles.
(November 2017) This writeup overviews the four steps to writing and using proper chemical reactions.
(November 2017) The mole is the primary currency of chemical reactions. The trick to remember, is that the mole is just an amount, like gallons or pounds.
