Can you please help me with my homework this is due in 4 minutes :)))

I'd answer, but I dont really know what it's talking about.

Explanation:

The process of making glass involves a chemical change. While a physical change describes change in the superficial properties of a substance-- like melting ice into water, or tearing up a piece of paper-- a chemical change alters the chemical makeup of the substance itself. Glass can undergo physical changes, too!

there all right good

the nucleus together due to an excess of either protons or neutrons.
