Copper, 1.04 g is dissolved in nitric acid, to produce copper(II) nitrate, which when reacted with NaOH and heated, produces 1.19 g of copper oxide, which is isolated and dried. What is the percent yield for the production of copper oxide?

Answer to the nearest integer without the % sign (example: 74)

write the balanced equation for the following reactions.

1. Copper + nitric acid ---> copper(II) nitrate + nitrogen dioxide + water

Copper(II) Nitrate + NaOH

2. changing copper(II) nitrate to copper(II) hydroxide

(Unless specifically stated do not assume water is a reactant or product; often it is only a medium in which the reaction occurs.)

3. Changing copper(II) hydroxide to Copper(II) Oxide.

(Water is also formed in this reaction)

4. Changing Copper(II) Oxide to Copper(II) Sulfate.

Copper(II) oxide + H2(SO4)

(Water is also formed)

5. Changing Copper(II) Sulfate to Copper

Copper(II) + zinc ---> Copper + Zinc sulfate

6. Zinc + Hydrochloric acid ---> Hydrogen Gas + Zinc Chloride

Under a certain set of conditions, the reaction of copper(II) nitrate with sodium hydroxide produces copper(II) hydroxide in 96.5% yield. What mass of copper(II) nitrate would be required to produce 11.4 mg Cu(OH)2 under these conditions?
