Question

Is this reversible? “ it was silver in color at start but it burned brightly and formed a white powder after heating.”

Answer 1

Hey there!

This is not reversible.

We know that this is a chemical change because heat is released (it burned brightly) and it formed a new substance (white powder).

Chemical changes are usually not reversible.

Since this is a chemical change, then this is not reversible.

Hope this helps!
