I really just need all the equations, please and thank you. MATERIALS: cene nitric acid, HNO, 3.0M sodium hydroxide, NaOH 6.0 M sulfuric acid, H2SO4 zine metal DI water PROCEDURE: Make sure you record detailed observations after almost every step. You will also need to write the balanced chemical equations for almost every step. Make sure you answer any questions associated with a step 1. Weigh approximately 0.5 g of copper metal and record the weight. Place the copper in...

PartA: Penny-→ Cu2+(aq) Make sure it is dated prior to 1982. Record mass to nearest 0.001 I. Weigh a copper penny. grams. 2. Place 450 mL of distilled water in a clean 600-mL beaker. Place the beaker on a hotplate and heat until the water boils. Do not wait for the water to boil now, but proceed with the rest of the experiment. You will need this water for rinsing in step C3. CAUTION. You will generate poison°แs nitrogen dioxide...
just making sure did I do right in number 10. and im confused at number 11 and 12 13. becausse we didnt learn in class. please help. thanks for your patient PROCEDURE 1.
