QuestionAnswer
Chemists use [...] to calculate the amounts of reactants they need for a desired amount of product. Chemists use stoichiometry to calculate the amounts of reactants they need for a desired amount of product.
Stoichiometry is the science of using the right amount of [...] to get the right amount of [...]. Stoichiometry is the science of using the right amount of reactants to get the right amount of product.
The word stoichiometry was coined from Greek words meaning "[..]" and "measure." The word stoichiometry was coined from Greek words meaning "element" and "measure."
To use the right ratio of reactants to products, chemists start with [...] equations. To use the right ratio of reactants to products, chemists start with balanced equations.
The [...] show how many copies of each molecule or formula unit are present. The coefficients show how many copies of each molecule or formula unit are present.
The [...] show how many atoms are in each molecule or formula unit. The subscripts show how many atoms are in each molecule or formula unit.
Balanced equations give you the [...] of reactants to products, but their actual amounts can be stated in different ways. Balanced equations give you the ratios of reactants to products, but their actual amounts can be stated in different ways.
