Question

We will create a model to help us investigate whether acid affects copper.

Prediction
Write a prediction about what you think will happen to the copper squares.

Answer 1

This is a cycle of reactions, because you start and end with the same substance, copper metal. In the first reaction, copper metal is oxidized by nitric acid to form copper (II) nitrate, Cu(NO3)2. ... Finally, the copper ions in the copper sulfate are reduced to copper metal by magnesium.
