A reaction that changes a compound into its constituent elements.
A reaction that starts with two or more elements and produces one compound.
Complete combustion reaction
A reaction in which O2 is added to a compound containing carbon and hydrogen, producing CO2 and H2O.
Incomplete combustion reaction
A reaction in which limited O2 is added to a compound containing carbon and hydrogen, making CO or C and H2O.
Incomplete combustion reaction in cars
Incomplete combustion often occurs, causing CO to be made. Cars have catalytic converters that convert CO to CO2.
The atomic mass of an element telling us how heavy it is. (Below the molecule on the periodic table of elements) 1 amu = 1.66 * 10(to the -24) g.
1 mole = 6.02 * 10 (to the 23) atoms or molecules in a substance. (often called Avogadro's number because he discovered it) The AMU of an atom or molecule = 1 mole of that substance. In equations, the coefficients to the left tell you the # of moles in the equation.
The stoichiometric coefficients in a chemical equation relate the volumes of gases in the equation as well as the number of moles of substances in the equation. (only works if everything you are using in the equation is a gas)
A chemical formula that provides the number of each type of atom in a molecule.
A chemical formula that tells you a simple, whole number ratio for the atoms in a molecule.
The mass of one mole of a given compound.
The system of relating the quantities of different substances in a chemical equation.
A reactant that runs out first, limiting the amount of product that can be formed in the chemical reaction.
