Question

what do we observe when we get copper with the help of burner write the chemical equation​

Answer 1

Answer:

What happens when copper is heated in air chemical equation?

It can be formed by heating copper in air at around 300–800°C: 2 Cu + O2 → 2 CuO. ... 2 Cu(NO3)2(s) → 2 CuO(s) + 4 NO2(g) + O2(g) (180°C)..

Explanation:

One of the most common iron oxides is iron (III) oxide, known as rust. The chemical formula for rust is Fe2O3. Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3.
