Document Summary

Oxidation numbers are used to represent charge on each individual atom. Balancing redox equations means you follow the rules. Molar ratio of reactants and products to each other. Reactant stoichiometry when burning propane is 1 propane to 5 oxygen molecules. 1 propane is equal to 3 co2 after burning. When converting between molecules always convert through moles. Measuring the volume of a standard solution required to react with a measured amount of sample. Equivalence point: point at which the reaction is complete at titration. Chemical equations relate how much of everything in the equation. Before you knew there were 3 oxygen atoms for every fe2o3. Mole of starting material how much product is made. You don"t always react exactly 1 mole of propane with 5 moles of oxygen. Sometimes we carry out reactions where there is an excess of one or the other.
