Stoichiometry Flashcards
What is Stoichiometry
the branch of chemistry that tells us the relationship between amounts of rectants and products in a chemical reaction
What is the molecular formula
formula which shows the number and type of each atom present in a molecule of that compound
what is the empirical formula
formula which shows the simplest whole number ratio of the numbers of different atoms present in the molecule
how to get molecular formula
empirical formula x N
1 mole of any gas at stp has a volume of
22.4L
explain the limiting reactant
when carring out chemical reactions its common for chemists to use and excessive amount of one or more of the reactants in order to increase the yeild of products
what is the yeild of a product
the amount of a product formed in a chemical reaction
what is theoretical yeild
the yeild calculated from the equation,it assumes the reaction is 100% efficent
what is actual yeild
the yeild that is obtained in practice
how to get percentage yeild
actual yeild / theoretical yeild x 100
