Lecture 18 Flashcards
Empirical Formula from Combustion Analysis
Convert to mass> divide by smallest mass to determine ratio> determine the mole ratios to determine the empirical formula
The ______ of one reaction often becomes the reactant in the next
Product
What should be eliminated from the net reaction
Intermediates
What is a reaction intermediate
any substance that is on both the product and reactant side in the the elementary steps that shouldn’t be included in the overall equation
Stoichiometry
quantitative aspects of a chemical reaction
What do the coefficients in a balanced chemical equation represent?
relative # of reactant and product particles
The mole ratios from balanced equations are used as
conversion factors
General pathway for stoichiometry
write chem equation> convert substances into moles> use coefficients to calculate # of moles. convert to desired units
The reagent in short supply that limits the amount of product that can be formed
limiting reagent
