100
The type of bond that allows electrons to move freely as the "sea of electrons"
What is a metallic bond?
100
Having these is the reason that salt has a higher boiling point than sugar
What are strong intramolecular bonds?
100
In this type of reaction any type of energy is released
What is exergonic?
100
Doing this increases the pressure and the reaction rate of a chemical reaction
What is a decreasing volume?
100
This concept states that particles must bump into each other in order to react
What is the collision model?
200
This is a type of intramolecular bond that occurs between a metal and a nonmetal
What is an ionic bond?
200
This type of material (think intramolecular bond) is dull in appearance
What are covalent compounds?
200
A cold pack is an example
What is endothermic and endergonic?
200
If surface area increase this happens to the reaction rate
What is increase?
200
Ways to indicate this is a double headed arrow or two arrows pointing in opposite directions on top of each other, a ________ reaction
What is a reversible reaction?
300
This type of bond holds molecules to other molecules
What is intermolecular bonds?
300
The sea of electrons allows this material to be conductive
What is metals?
300
In this type of reactions more energy is needed to break bonds than is released when the new bonds are formed
What is an endergonic or endothermic reaction?
300
This is a substance that increases the rate of chemical reactions
What is a catalyst?
300
Changes of state is an example of this process
What is a physical change?
400
Ionic, covalent, and metallic bonds
What are intramolecular bonds?
400
Ionic compounds have this type of boiling point because of its intramolecular bonds
What is a high boiling point?
400
This image shows what is happening to the energy in the reaction
What is energy being absorbed?
400
Inhibitors do this to chemical reactions
What is slow or stop chemical reactions?
400
We use these in food to keep it from decomposing
What is inhibitors or food preservatives?
500
These types of bonds are considered to be weak
What are intermolecular bonds?
500
Water has a higher boiling point than methane, even though they have similar mass, because water is this type of molecule
What is polar?
500
This requires energy to happen during a reaction
What is breaking bonds?
500
Increasing the concentration does this to the number of particles
What is increases the number of particles?
500
This is when the forward and reverse paths of a reaction have the same rate
What is equilibrium?
