1984, Union Carbide Plant – 10000+ killed in Bhopal, India by Methyl Isocyanate 1988 Pepcon, Henderson Rocket Fuel Explosion
Objectives • To understand more of the information given in a balanced equation • To use a balanced equation to determine relationships between moles of reactant and products
A. Information Given by Chemical Equations • A balanced chemical equation gives relative numbers of reactant and product molecules (or moles) that participate in a chemical reaction. • The coefficients of a balanced equation give the relative numbers of molecules (or moles). CO(g) + 2H2(g) CH3OH(l) How many moles of CH3OH will be produced from 1, 2, or 5 moles of CO? How many moles of hydrogen will react with 1, 2, or 5 moles of CO?
B. Mole-Mole Relationships in a BALANCED Reaction • A balanced equation can predict the moles of product that a given number of moles of reactants will yield. What number of moles of O2 will be produced by the decomposition of 2, 1, or 5.8 moles of water?
B. Mole-Mole Relationships using Factor Analysis • The mole ratio allows us to convert from moles of one substance in a balanced equation to moles of a second substance in the equation. Use factor analysis and mole ratios to calculate the answers below: CH4(g) + 2O2(g) CO2 + 2H2O(l) 4.2 moles of CH4 reacts with how many moles of O2? How many moles of H2O will be produced?
