what is chemistry
chemistry is the study of matter and the changes it undergoes
100
What is volume
volume is the amount of space occupied by an object
100
state of matter with definite shape and volume
solid
100
what is the law of conservation of mass
energy can never be created nor destroyed
100
what is an atom
the smallest particle of an element
200
What is matter
Matter is anything that has mass and occupies space
200
What is an extensive property
a property that depends on the amount of matter in an object
200
state of matter with no definite shape and no definite volume
gas
200
What happens during a chemical change
The composition of matter always changes
200
what is an electron
negatively charged
300
what is mass
a measure of the amount of matter in an object
300
what is an intensive property
intensive property depends on the type of matter in an object
300
State of matter with no definite shape but has a definite volume
liquid
300
what is a reactant
is present at the start of the experiment
300
what is a proton
positively charged
400
What is the SI unit for mass

400
What is a substance
matter that has uniform and definite composition
400
what is vapor
describe matter in the gaseous state that is typically solid or liquid at room temperature
400
What is a clue that a chemical change has taken place
transfer of energy change in color production of gas (bubbles) formation of a precipitate
400
where are protons found
in the nucleus
500
What are the five traditional areas of study in chemistry

how many phases does a heterogeneous mixture have
2 or more
500
what is the ideal gas law equation
PV=nRT

what is distillation
the process in which liquid is boiled the vapor is collected and cooled it is used to separated solid particles from liquid
500
what is daltons atomic theory
the first theory to relate chemical changes at the atomic level
