Stoichiometry

Atoms cannot be created or destroyed, only rearranged. The number of atoms cannot be changed by chemical reactions.

the quantitative study of the reactants and products in a chemical reaction.

the number written immediately before the atoms, ions and molecules in a balanced chemical equation

the ratio between the amounts in moles of any two compounds involved in a balanced chemical reaction

starting materials and are written on the left-hand side of the equation.

the end result of the reaction and are written on the right-hand side of the equation

the reactant used up completely in a chemical reaction. Also produces the smallest amount of product

the reactant leftover after the reaction, produces the most product

a technique where a solution of known concentration is used to determine the concentration of an unknown solution, in this case an acid and a base react with each other to form water and a salt.

a technique where a solution of known concentration is used to determine the concentration of an unknown solution

the ratio of experimental and theoretical yields of product

the actual amount of product you obtain when performing a given experiment, (will be given in a problem)

fractional uncertainty expressed as a percent, ex If L = 6.0 ± 0.1 cm, its is 1.7%.

the difference between estimated value and the actual value in comparison to the actual value

the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances

Aqueous or solvent free reactions Use of renewable starting materials Mild reaction conditions Efficient catalysis Use of any by-products produced during synthesis.

a measure of the desired useful products formed from reactants in a chemical reaction and stated as a percent
