STATES OF MATTER
All particles are always in this type of motion
Constant motion
When you squeeze a gas, this goes up.
Pressure
What is a homogeneous mixture?
A mixture that looks the same all throughout.
A reaction that gives off heat
Exothermic
A Ph, below 7 is this.
Acidic
This is the measure of how hot or cold something is
Temperature
When you heat a gas, this goes up.
Volume
What is a heterogeneous mixture?
A mixture where you can see different parts.
A reaction that absorbs heat
Endothermic
A Ph, above 7 is this.
Basic
What is the force that air pushes down with?
Air pressure
This law combines pressure, volume, and temperature.
Combined gas law
Moles of solute divided by liters of solution
Molarity
What law states that energy cannot be created or destroyed?
Law of Conservation of Energy
Acid+ base gives you this.
Salt and water
What is it called when liquid changes into a gas?
Vaporization
What type of relationship do pressure and volume have according to Boyle's Law?
Inverse Relationship
What is it called when you add water to a solution to make it weaker?
Dilution
What speeds up a reaction?
A catalyst
This tells you how strong or weak an acid is
pH
What is the strongest kind of intermolecular force?
Hydrogen bonding
Why are gases easier to compress than solids or liquids?
Because gas particles are far apart compared to the particles in solids and liquids.
How do you calculate percent by mass?
Mass of solute / mass of solution x 100
The minimum energy needed for a reaction to happen
Activation energy
A lab experiment where you find an unknown concentration.
Titration
