This folder contains resources about the conservation of matter and stoichiometry.
This unit is part of the Chemistry collection, an open source California digital textbook plus supplementary resources.
011 - Symbolic RepresentationsIn this video Paul Andersen explains how the conservation of matter can be displayed with both symbolic representations and particulate drawings. A simple conservation of matter problem is also included.
012 - Conservation of AtomsIn this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The mass of an anylate can be determined through both gravimetric analysis and a titration.
