offset A.
After sanding the bulls eye its luster was greater.
1. As the cop heats up it turns to a bright orange.
2. The magnesium strip destroy in truth brightly for a short time.
Part B
1. The copper carbonate is a green gunpowder.
2. The copper carbonate powder turns from a green powder to a black liquid.
Part C.
1. The zinc in the test tube when added with the HCl acid right away starts to fizz and bubble.
2. The hydrogen gas pops as you place a intense stick in it and turns black.
3. The zinc starts to deteriorate subsequently adding copper(II) sulfate
Part D.
