fewer steps are required to solve stoichiometry problems when

the reactant is given in moles and the product is sough in moles

in stoichiometry, molar mass is used to

relate the mass of a substance to the amount in moles of that substance

a balanced chemical equation allows one to determine

mole ratio of any two substances in the reaction

the coefficients in a chemical equation represent the

relative numbers of moles of reactants and products

in most reaction, the amount of product obtained is

less than the theoretical yield

Stoichiometry is the branch of chemistry that deals with elements in compounds, products in reactions, focusing on:
energy transfers
bonding
physical characteristics
mass relationships
4
fewer steps are required to solve stoichiometry problems when
the reactant is given in grams and the product is sough in grams
the reactant is given in moles and the product is sough in moles
the reactant is given in grams and the product is sough in liters
the reactant is given in liters and the product is sough in atoms
5
in stoichiometry, molar mass is used to
convert amount of moles of one substance to an amount in moles of another
relate the mass of a substance to the amount in moles of that substance
balance a chemical equations
determine the mole ration
6
a balanced chemical equation allows one to determine
electron configuration of all elements in the reaction
mole ratio of any two substances in the reaction
mechanism involved in the reaction
energy released in the reaction
7
the coefficients in a chemical equation represent the
number of atoms in each compound in a reaction
masses, in grams, of all reactants and products
number of valence electrons involved in the reaction
relative numbers of moles of reactants and products
8
if a chemist calculates the max amount of product that could be obtained in a chemical reaction, they are calculating
theoretical yield
mole ratio
percentage yield
actual yield
9
the participation of reactants in a chemical reaction is restricted by the
limiting reactant
excess product
excess reactant
limiting product
10
in most reaction, the amount of product obtained is
equal to the theoretical yield
more than the percentage yield
less than the theoretical yield
more than the theoretical yield
11
actual yield must be determined by
theoretical yield
estimation
experiements
calculations
