|
Product |
the substances that are formed during a chemical reaction - arrows point towards the product |
|
|
Reactant |
the substances present before a chemical reaction occurs
- arrow points away from the reactants |
|
|
Coefficient |
the number placed in front of a chemical formula to indicates the number of molecules present -> 2H2 + O |
|
|
Chemical Equation |
predicting the reactions that occur when two substances are put together |
|
|
Synthesis "Love at first sight" |
a reaction in which two or more elements or compounds combine to form a more complex compound A+B -> AB |
|
|
Decomposition "The big breakup" |
the breaking down of a compound into elements or simpler compounds as chemical bonds are broken and atoms or ions are rearranged AB -> A + B |
|
|
Combustion "The Player" |
burning of a substance in the presence of oxygen
AB + O -> AO +BO |
|
|
Single Replacement "My best friend's girlfriend" |
a reaction in which one atom or ion in a compound is replaced by another atom or ion
AB + C -> BC + A |
|
|
Double Replacement "Revenge" |
a chemical reaction between two compounds where the cations in two compounds switch the anions they are bonded to, resulting in two new compounds
AB + CD = AD + CB |
|
|
Limited Reactant |
the reactant in a chemical reaction that limits the amount of product that can be formed - stops when all of the limiting reactant is consumed |
|
|
Excess Reactant |
the reactant in a chemical reaction that remains when a reaction stops when the limited reactant is completely consumed - left over stuff afterwards - remains because there is nothing with with which it can react |
|
|
Law of Conservation of Matter |
the law that states that during a chemical reaction matter cannot be created or destroyed |
|
|
Molar Mass |
measure of the average molecular mass of all the molecules in an element or compound. It is the mass of the substance (typically in grams) per amount of the substance (in moles) |
|
|
Mole |
an SI unit for the measure of a quantity |
|
|
Avogadro's Number |
the number of particles in a mole, defined to be a quantity of 6.022 × 1023 |
|
|
Balanced Chemical Equation |
an mathematical representation of a chemical process; contains chemical formulas and coefficients |
