Question

So our professor didn't go over this but is freshly cut sodium, but rapidly tarnishes on contact with air a physical or chemical property?​

Answer 1

Hey!

After the slight confusion (haha)...

Your answer should be a CHEMICAL CHANGE / PROPERTY

Step-by-step explanation:

Its CHEMICAL because the sodium has reacted with the air (oxygen in technical terms) which then forms SODIUM OXIDE...the tarnishing of the cut sodium surface it a thin layer of the SODIUM OXIDE...

HOPE THIS HELPED!
