because it is tough, keeps whatever is inside it in and it is not easily broken
To protect them from rust.
to prevent it from corroding / rusting
Zinc coating avoid corrosion.

The history of ZincCenturies before zinc was discovered in the metallic form, its ores were used for making brass and zinc compounds were used for healing wounds and sore eyes. Brass was produced by the Romans in the time of Augustus (20 B.C. - 14 A.D.). By 1374, zinc was recognized in India as a new metal and at Zawar, India, both zinc metal and zinc oxide were produced from the 12th to the 16th century. From India, zinc manufacture moved to China in the 17the century. Zinc was recognized as a separate metal in Europe in 1546. In 1743, the first European zinc smelter was established at Bristol in the United Kingdom.
to ensure that all the sulphuric acid has been used up

Yes zinc is used in pennies and it is used in sunscreen.
Metalic Zinc is used for rust prevention as a coating on iron alloys (steels) as a major component in many casting metals, as the second largest alloying metal in brass(the first being copper).
