Chemical Reaction When a substance goes through a reaction and changes into another substance.
Chemical Equations A formula which shows how elements or compounds react to form new compounds
2H + + O -2 H 2 O
Parts of a chemical equations Reactants Yield Sign Products
Reactants The elements or compounds that are found on the left side of the yield sign
Yield Sign An arrow found in the equation which works like an equal sign
Products The elements or compounds that are found on the right side of the yield sign
Coefficient Is the number found in front of an ion or compound. It tells the number of that ion or compound you have
Balanced Equation For each element in a chemical equation, the same number of each element must be found on the left side of the arrow as on the right side
All chemical equations must be balanced.
To balance an equation, you can change the coefficient. However, you can never, never, never change the subscript.
Symbols used in Chemical Equations (l) The chemical is a liquid. (s) The chemical is a solid. (g) The chemical is a gas. (aq) The chemical is aqueous (dissolved in water).
Synthesis Reactions A reaction where the reactants combine to form a bigger compound (also known as combination)
Synthesis Reactions 2H + + O -2 H 2 O
Decomposition Reaction A reaction where the reactants break down (decompose)
Decomposition Reaction H 2 O 2H + + O -2
Single Displacement Reaction A reaction where one element replaces another element in a compound
Single Displacement Reaction 2Al Ag 2 S Al 2 S 3 + 6Ag 2+
Double Displacement Reactions A reaction where the positive ion of two compounds switch, which forms two new compounds
Double Displacement Reactions HCl + NaOH NaCl + H 2 O
Combustion A reaction in which a compound (often carbon) reacts with oxygen
Combustion C + O 2 CO 2 CH 4 + 2O 2 CO 2 + 2H 2 O C 3 H 8 + 5O 2 3CO 2 + 4H 2 O C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O
Redox Reactions A reaction where one compound loses electrons and becomes a smaller compound, while another compound gains electrons and becomes a bigger compound.
Redox Reactions C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O
Oxidized Compound The compound that loses electrons and becomes a smaller compound
Reduced Compound The compound that gains electrons and becomes a bigger compound
Oxidation-Reduction Reaction Another name for the Redox Reaction
