If zinc is more reactive than copper, what happens when zinc is added to copper(II) sulfate solution?

Zinc displaces copper, so copper is deposited

Why is a very reactive metal such as aluminium extracted by electrolysis?

Because it is too reactive to be reduced by carbon

Because it is very unreactive, so it does not combine with other elements

A hydrocarbon made only of carbon and hydrogen

It is toxic and reduces the blood's ability to carry oxygen

About 78% nitrogen and 21% oxygen

Gases such as carbon dioxide trapping heat radiated by the Earth, warming the lower atmosphere

a mixture of hydrocarbons that can be separated into useful fuels
