What is an atom?
Are the tiny particles that are the basic building blocks of all matter
Each atom has a nucleus made of protons and neutrons
Surrounding around the nucleus are the electrons.

gas, liquid, solid, and plasma
200
What is a molecule?
Are made of two or more atoms that are connect or bonded together
200
What is a freezing point depression?
Is when you add something to a liquid solution to reduce the freezing point.
200
What is Combustion?
A chemical reaction between substances, usually including oxygen accompanied by heat and light in the form of flame.
300
Say the Pledge

What are the two changes of Chemistry? Explain each.
Chemical Change : is any change that causes a new substance to be formed.
Physical Change : is a change from one state of matter to another without changing its identity.
300
What is Vaporization?
The conversion of SOLID or LIQUID to GAS
300
What is a melting point?
The temperature at which a given solid will melt to a liquid.Melting Point for substances are always different
300

Harley, Jeremiah, Kimberly, Jasmin, Ms. Glenda, Gabby, Monique
400
What is oxidation?
is a chemical reaction that takes place when a substance combines with oxygen.
400
Name two types of Vaporization? and explain.

Solid to Gas = Sublimation
400
Name and explain the two types of melting point.
Melting point of water 32℉
Boiling point of water is 212℉
400
Name all the activities we've done since day 1.
Fruit Oxidation

500
What is the name of the Guam 4-H Program Leader?
Clifford Kyota
500
Explain why lemon was so effective when we did the fruit oxidation experiment?
lemon juice keeps the apple from browning, because it is full of ascorbic acid
Oxygen will react with the acid before it will react with apple.
500
Name 5 elements of the periodic table.
500
What are the two special kinds of chemicals?
Acids: has a lot of hydrogen ions in them
base : has a lot of hydroxide ions in them
