molecule. solution. compound. 20 Points

Slide 11:The SI unit of mass is the

ounce. kilogram. liter. 40 Points

Slide 12:In chemical reactions, the law of conservation of energy means that

energy is always lost. the total amount of energy stays the same. energy is always gained. 60 Points

compounds. mixtures. solutions. 80 Points

Slide 14:How do liquid H2O, ice and water vapor differ from each other?

They are different states or phases of matter. They are different compounds. They are made up of different kinds of atoms. 100 Points

Slide 15:A solid is a state of matter that has a(an)

indefinite volume and indefinite shape. definite volume and definite shape. indefinite volume and definite shape. 120 Points

Slide 16:Particles of a liquid

have no viscosity. are tightly packed together and stay in a fixed position. are free to move throughout a container but remain in close contact with one another. 20 Points

the temperature inside the balloon increases. the volume of the balloon increases. the volume of the balloon decreases. 60 Points

Slide 19:On a long trip, a truck�s tires can get very hot and cause

their volume to decrease. their pressure to increase. their pressure to decrease. 80 Points

Metals Nonmetals Metalloids 60 Points

Slide 25:The factor that determines how an atom interacts with other atoms is its

number of valence electrons number of protons number of neutrons 80 Points

Slide 26:How did chemists change Mendeleev�s periodic table in the early 1900�s?

They included physical properties such as melting point and density. They used atomic mass instead of atomic number to organize the elements. They used atomic number instead of atomic mass to organize the elements. 100 Points
