Chem 1075 Chapter 10 Stoichiometry Lecture Notes Slide 2 What is stoichiometry? Chemists and chemical engineers must perform calculations based on balanced chemical reactions to predict the cost of processes. These calculations are used to avoid using large excess amounts of costly chemicals. The calculations these scientists use are called stoichiometry calculations. Slide 3 Interpreting Chemical Equations 2 NO(g) + O 2 (g) 2 NO 2 (g) Slide 4 Moles and Equation Coefficients 2 NO(g) + O 2 (g) 2 NO 2 (g) NO (g) O2(g) NO2(g) molecules molecule molecules molecules molecules molecules molecules molecules molecules moles mole moles Slide 5 Mole Ratios (Coefficient Ratios) 2 NO(g) + O 2 (g) 2 NO 2 (g) We can now read the balanced chemical equation as “_______________________________ gas react with _________________________________ gas to produce ________________________ gas”. The coefficients indicate the ________________________________, or the ratio of the moles, of reactants and products in every balanced chemical equation. This mole ratio is also called the _________________________________________ PDF created with FinePrint pdfFactory trial version http://www.pdffactory.com
