Why is the Statue of Liberty green?
The copper coating reacted with the air, so it turned from a dull brown color to green.
The copper coating wore off and the statue was was green underneath.

The total mass (weight) of the substances before and after a reactions will stay the same
How does the weight of a balloon change once it is inflated?
A balloon will weigh less once it is inflated because it has been filled with air and that air has a mass.
A balloon will weigh more once it is inflated because it has been filled with air and that air has a mass.
A balloon will weigh the same once it is inflated because it has been filled with air and that air has a mass.
