Investigation: Finding the Missing Mass |
Some people think that gases have no mass or
even that gases have negative mass. They look at hot air balloons
rising into the air and say that the gas inside a balloon makes
it weigh less. How can you explain this observation?

Balancing Chemical Equations |
Follow the links to Web sites that show how
to balance chemical equations. Choose a reaction and show it as
a word equation, a skeleton equation, and as a balanced equation.

Types of Chemical Reactions: Single and Double Displacement |
One way that displacement reactions may be
applied is in the process of refining metal such as aluminum and
copper from their minerals. Find out more about displacement reactions
in refining metals.
