What is a colloid?
A mixture that does not settle into its component parts once it has been mixed, no matter how long it sits.
A type of mixture where liquid particles are dispersed into another liquid, often with the help of another binding substance.

A solution.
A pure substance.
A heterogeneous mixture.

In a water-and-oil emulsion, what will happen to the oil?
The oil will eventually band together and sink to the bottom.
The oil will eventually band together and rise to the top.
The oil will stay mixed throughout the water.
The oil will float in the centre of the mixture.
What type of substance do you add to certain kinds of mixtures to keep them from separating?
An emulsion.
An emulsifier.
A solute.
A binder.
What is the difference between homogeneous mixtures and solutions?
There is no difference, they are exactly the same.
All solutions are homogeneous mixtures, but not all homogeneous mixtures are solutions. When a homogeneous mixture contains only one phase, then it is a solution. When it contains more than two phases, it is homogeneous.
Air is an example of a homogeneous mixture of nitrogen, oxygen, carbon dioxide, and other gases present in air. It cannot be a solution because it does not have completely dissolved particles.
