Exam Review Question 6

6.    What is the difference between a solution and a heterogeneous mixture? A solution and a compound? Give an example of each.

The difference between a solution and a homogenous mixture is that a solution is homogenous, meaning it is evenly mixed throughout, but a heterogeneous is not evenly mixed, like a soup or salad and a solution is like a coke or Dr. Pepper.  Both solutions and compounds are homogenous, but compounds are chemically bonded together like sterling silver which is a mixture between silver and copper.

Aluminum Foil

I chose common house hold aluminum foil.  I chose it because it is an important part of our modern day world.  Aluminum is an important resource and good building material because of is light weight and malleability.  Aluminum foil is used any were, from keeping food warm or molding into fun shapes.  Aluminum foil also makes for a fun chemistry project!  To take a more in depth view click here.
