Lecture
This lecture covers the basics of chemical equations, including the general form of reactants turning into products, balancing equations with stoichiometric coefficients, and the principles of conservation of atoms and charge. Examples are provided to illustrate the process of balancing equations and determining the state of physical matter involved. The lecture also delves into stoichiometry, calculating the masses of compounds involved in reactions, and identifying the limiting reactant. Various examples are presented to demonstrate these concepts.
