Question

In the activity "Producing Circuit Boards," you used a solution to etch copper. Based on what you have

learned in this and previous activities, explain what happened to the copper that was removed from the
copper-coated plastic. Use the law of conservation of mass to explain your reasoning.

Answer 1

The law of conservation mass states that mass is neither created or destroyed in chemical reactions.

Step-by-step explanation:

I'm guessing the copper stayed the same; use the above definition to explain.

Answer 2

The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
