This is the universal solvent
Water
These are the two most reactive families on the periodic table of elements
The Halogen and Alkali Families
This type of circuit is one where electricity is flowing through the wire.
Closed circuit

Any change of a material into a new material with different properties
describes a solution that holds the total amount of solute that it can hold under given conditions
Saturated
Sour taste, corrosive, conductive, pH < 7.0
Acids
The formula that describes Newton's 2nd Law
F=MA
The acceleration of an object that goes from 10m/s to 15m/s in 4 seconds
1.25m/s2
The amount of matter in an object
Mass
Energy is released in this chemical reaciton
Exothermic
Energy is absorbed in this type of chemical reaction
Endothermic
Type of circuit where the resistors are all the same wire
series circuit
The acceleration due to gravity on a rock that falls for 11 seconds and is 982m down (2 decimals)
16.23 m/s2
A combination of compounds and elements that has not formed a new substance and whose proportions can be altered without changing the identity of the substance
Mixture

Base
The five things that we can do to change the reaction rate in a chemical reaction.
Stir/shake
change the temperature
change surface area
add a catalyst or inhibitor
change the concentration
Law of Conservation of Energy
