Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the chemical formula?CuO
2. What is the mineral name?Tenorite
3. Why is it called black powder?It is black because the copper atoms in it give the powder a dark color. The black color comes from the way light is absorbed by the copper and oxygen atoms.
4. How is Copper(II) oxide made?Copper(II) oxide is made when copper metal is heated with oxygen. This can happen in factories that clean copper or when copper is melted and left to rust at high temperatures.
