You might have noticed that new copper roofs turn green over time. This occurs because copper reacts with substances in the air to form a hard, protective coating. Will the mass of the new copper roof increase or decrease over time? Explain. Does this prediction violate the law of conservation of mass? Explain. (4 marks)

Answer:

the mass of the new copper roof will increase over time as it turns green

Explanation:

this is because copper will react with atmospheric substances to form copper compound. this does not violate the law of conversation of mass because the mass increases as copper react with atmospheric substances in the presence of atmospheric air, oxidizes to copper compounds which are heavier in mass than copper atoms

According to the law of conservation of mass, the mass of the copper roof increases as oxygen is added to it to form copper oxide.

What is oxidation?

Oxidation is a reaction in which oxygen is added to an element.

Oxidation metals in the presence of air occurs frequently as metals are reactive.

Copper roof turns green with time as the metals react with oxygen in air to form copper oxide.

The mass of the new copper roof increases in accordance with the law of conservation of mass as oxygen is added to metallic copper to increase it's mass.
