Answer 1

Chemical characteristics refer to properties of a substances that determine how (or if) it will undergo a chemical reaction.

Physical characteristics refer to properties of a substance that are intrinsic to that substance (e.g. what state it's in, how hard or shiny it is, its mass, etc).

Use this information to answer your question!

Answer 2

ok, so for example 1 would me chemical?

Answer 3

Yes!

Answer 4

I'm very new to this subject, you mind walking me through? If not I understand. xP

Answer 5

nvm I'm finished. xD Thank you for the help! :D

Answer 6

Well the first one is chemical because we're talking directly about a chemical property of sodium. It says "reactive" in the statement so already that's a clue.

The next one says oxygen is a gas. So we're talking about the phase (or state) the sample of oxygen is in. This is a physical characteristic and doesn't directly tell us anything about its chemistry.

Does that makes sense? Keep trying the others and let me know if you have any questions!

Answer 7

Oh ok no problem!
