A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products.
A chemical change in which two or more substances react to form a single new substance.
A reaction in which a single compound breaks down to form two or more simpler substances.
A reaction of an element and a compound that yields a different element and a different compound (A + BC ---> AB + C).
A reaction of two compounds to produce two different compounds by exchanging the components of the reacting compounds (AB + CD ---> AC + BD).
A chemical substance formed as a result of a chemical reaction.
Element or compound that enters into a chemical reaction.
the SI base unit used to measure the amount of a substance (mass/grams) whose number of particles is the same as the number of atoms of carbon in exactly 12 g of carbon-12 (6.022 x 10^23).
6.022 x 10^23. The number of particles in exactly one mole.
The mass of one mole (6.022 x 10^23 atoms/molecules) of a substance.
The sum of the average atomic masses of all the atoms represented in the formula of any molecule, formula unit, or ion.
The sum of the masses (AMU) of all the atoms in a molecule; sometimes called molecular weight.
A branch of chemistry that deals with the relative quantities of reactants and products in chemical reactions. EX. For every one mole of reactant we have 2 moles of X product & 1 mole of Y product, or for 15 grams of reactant, how many grams of X product & Y product will you have?
Law of Conservation of Mass
Mass of an isolated system (closed to all matter and energy) will remain constant over time.
A chemical reaction in which water reacts with a compound to produce other compounds. Involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water.
Organic molecules that are composed of only carbon and hydrogen.
The percent by mass of each element in a compound.
A distribution of ions as shown by a mass spectrograph or a mass spectrometer.
A laboratory procedure for determining the composition of a substance by burning it completely in oxygen to produce known compounds whose masses are used to determine the composition of the original material.
A reactant that is consumed completely in a chemical reaction. The amount of product formed depends on the amount of the limiting reactant available.
The maximum amount of product possible in a chemical reaction for given quantities of reactants; also known as stoichiometric yield.
The amount of product obtained from a chemical reaction, which is often less than the theoretical yield.
The ratio, expressed as a percentage, of the actual yield of a chemical reaction of the theoretical yield.
