4.I have a question about the reaction of copper (II) oxide and sulfuric acid to form copper sulfate pentahydrate. ...

entahydrate. My students are varying either the mass of the copper oxide or the concentration of the sulfuric acid. They do not have an understanding of any chemistry calculations and only basic knowledge about chemical equations. They should have some knowledge of ionic equations and neutralistions reactions but I need to explain it to them in very basic terms. Without doing any calculations myself I can't explain it to them.
