In an experiment, the mass of a piece of copper is determined to be 8.56 g. Then the copper is reacted with sufficient oxygen gas to produce solid copper(II) oxide.

a. If copper has a density of 8.94 g/cm3, what is the volume (cm3) of the copper?

---

b. How many copper atoms are in the sample?

---

c. Write the balanced chemical equation for the reaction.

---

d. Classify the type of reaction.

---

e. How many grams of oxygen are required to completely react with the copper?

---

f. How many grams of copper(II) oxide will result from the reaction of 8.56 g of Cu and 3.72 g of oxygen?

---

g. How many grams of copper(II) oxide will result in part f. if the yield for the reaction is 85.0 percent?
