The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.
I think the answer to this problem I believe would probably be B. learned optimism. I think it's the closest answer...I THINK
'Heat' is another term to describe thermal energy, whether the thermal energy
just sits in some object or substance, or flows from one object to another one
that's cooler.
'Heat' is NOT another word for 'Temperature'. If you think of it that way,
then you'll have a hard time UNlearning that idea and getting yourself
unmuddled and straightened out. Please don't even go there.
105.9888 g/mol is the mass as far as i know, Don't know the amount of molecules tho.
mark me brainliestt :))
