Presentation transcript:

WARM UP Write oxidation and reduction half-reactions for the reaction: 2 H2 + O2  2 H2O. Write a net ionic equation for the reaction Pb(NO3)2 + 2NaI  PbI2 + 2NaNO3.

Stoichiometry Chemistry II

Stoichiometry Quantitative study of chemical reactions Number measurements Moles, grams, etc.

Yield Product made from reactant Mole method Use balanced coefficients Ex: 2 CO (g) + O2(g)  2 CO2(g) 2 moles CO will yield 2 moles CO2 2 moles O2 will yield 4 moles CO2

Limiting and Excess Reagents Limiting reagent Used up first, limits/determines yield Mole method Find moles of product formed from each reactant Reactant that gives lesser yield is limiting

Limiting and Excess Reagent Not used up, extra left over Mole method Amount of limiting reagent used Convert to excess reagent needed Subtract from given amount of excess reagent

WRAP UP Given the equation below, if you mix 17 moles of H2 and 13 moles of O2, how many moles of water will you make? What will be your limiting and excess reagents? How much excess reagent will you have left over?
