Review Matter Chemical Physical

Which mixture type contains the largest particles?

• suspension

• solution

• colloid

• There is no difference in particle size among the mixture types.

A homogeneous mixture is also called

• a colloid

• an element

• a compound

• a solution

An element is always made of

• more than one type of atom

• a single type of atom

• one type of molecule.

• We don't have enough scientific knowledge to tell.

Wood shavings and iron shavings are in a pile. As a magnet moves near the pile, the iron shavings move toward the magnet. What do you know?

• The pile is a suspension.

• The pile is a compound.

• The pile is a solution.

• The pile is a heterogenous mixture.
