Kyle Paulk SI CHEM 1201 Stoichiometry Rules for Stoichiometry: 1. Requires a correctly balanced reaction equation 2. Based on molar ratios (stoichiometric coefficients) 3. There are NO direct relationships between grams of substances (or volumes, concentrations, etc.) in a reaction; all masses, volumes concentrations, etc. have to first be converted into moles 4. The amount of prouct depends on the amount of reactant available in the smallest stoichiometric amount. We call such a reactant the : it gives the smallest amount of product, it gets completely consumed in the reaction, and you run out of it BEFORE the other reactant ( ) has a chance to get used up How many moles of PCl 3 can be theoretically produced from 2.41 moles of Cl

Unformatted text preview: 2 and an unlmited amount of P 4 ? How many grams of carbon dioxide (CO 2, Molar mass = 44.010g/mol) can be prepared from the complete combustion of 3.25g of acetylene (C 2 H 2 , molar mass 26.038 g/mol)? Kyle Paulk SI CHEM 1201 1 gram of propane is combusted. What is the mass of O 2 consumed? What mass of propane is combusted if 42.1g of steam is produced? Limiting Reagent Hamburger Example: How many moles of ammonia can be obtained from the reaction between 8.42g of hydrogen gas and 34.4g of nitrogen gas? 1. Write the balanced equation 2. Prepare moles of both reactants 3. Use the relevant molar ratio to find the limiting reagent (set up a cross proportion)...
