Chemical Equation
representation of a chemical equation
Skeleton Equation
an unbalanced chemical equation
Aqueous Solution
A solution that includes water.
Catalyst
A substance that speeds up a chemical reaction
Coefficients
the whole numbers in front of the solutions
Subscript
the whole number in the chemical equation
Balanced Equation
each side of the chemical equation has the same number of elements
What are the five general types of reactions?
Combination, decomposition, single-replacement, double-replacement, combustion
Combination
a + b= ab
Decomposition
ab = a + b
Single replacement
a + bc = ac + b
Double replacement
ab + cd = ad+ bc
Combustion
CxHx + O2 = CO2 + H2O
How much water makes up earth and humans?
70% Earth
60%-80% Humans
Spectator Ion
An ion in the equation that is not directly involved in the reaction.
Net Ionic Equation
an equation that only shows the particles that are involved in the reaction
