7) When baking soda and vinegar mix, what is released?

Because air is partly made of carbon dioxide.
9) When a full balloon (closed system) and an empty balloon (open system) were placed on a balance, the full balloon sank and the empty balloon rose. Why?

The full balloon had the same mass as the empty balloon.
B
Air has mass.
C
Air is invisible.
D
The empty balloon was heavier.

A
Less air is the balloon means less mass.
B
Less air in the balloon takes up more space.
C
Less air in the balloon means more mass.
D
Less air in the balloon makes the particles bigger.
11) You compare the mass of a full balloon and an empty balloon. Which statement is true?
A
The empty balloon will weigh more than the full balloon because of the mass of the air.
B
The full balloon will weigh less because of the tiny particles inside it.
C
The full balloon will weigh more than the empty balloon because of the mass of the air.
D
The 2 balloon will weigh the same because they are both balloons.

16) Which statement is TRUE?
A
If you combined baking soda and vinegar inside any closed container, nothing would happen because it is closed.
