A pure substance formed from chemical combinations of two or more different elements
What are compounds?
400
A typical unit of measure for solid volume
What is cubic centimeter?
400
One of the five characteristics of an atom
What is Atoms cannot be broken into smaller pieces, or In any element, all the atoms are exactly alike, or Atoms of two or more elements can combine to form compunds, or Atoms of each element have a unique mass, or The masses of the elements in a compound are always in a constant ratio.
400
The reason that the clear fresh water floated on top of the colored salt water
What is differences in density?

The two catagories that pure substances include
What are elements and compounds?
500
A typical unit of measure for density
What is g/mL?
500
A picture that scientists formed in their minds to explain the properties of elements and compounds by studying the atoms that form them
What is a particle model?
500
We determined its density by submerging it in water to determine its volume and then divided it into the mass
What is an irregular shaped object?
