VA.PS.3.c

Front

What does a balanced chemical equation demonstrate?

Back

The conservation of matter

How does the kinetic molecular theory explain the behavior of gases?

Back

Gas particles move the fastest, the move randomly, and are far apart.

VA.PS.2.c

Front

What is a physical change in a pure substance?

Back

A change in physical appearance (i.e. size, shape, color, state of matter) but it still remains the same substance.

VA.PS.3.b

Front

Describe ionic bonding.

Back

Transfer of electrons from one atom to another

Two molecules of water are produced.

Tags

VA.PS.3.d

Front

Analyze how the physical properties of a pure substance can be used to distinguish it from a mixture.

Back

Pure substances have consistent physical properties (it all looks the same). But in a mixture, you can identify the component parts.
