Question

Write a chemical equation of heating of cu and fe

Answer 1

Answer:

Metal + oxygen −→−−−Heating Metal oxide

Heating of Cu in presence of air -

2Cu(s) + O2(g) −→−−−Heating 2CuO(s)

Heating of Fe in presence of air-

4 Fe(s) + 3 O2(g) −→−−−Heating 2 Fe2O3(s)

Answer 2

Answer: The chemical equations for the heating of copper (Cu) is:          

                          2Cu(s) + O2(g) → 2CuO(s)

The chemical equations for the heating of iron (Fe) is:  

                        Iron: 4Fe(s) + 3O2(g) → 2Fe2O3(s)

When copper is heated in the presence of oxygen (O2), it undergoes oxidation and forms copper oxide (CuO).

When iron is heated in the presence of oxygen, it also undergoes oxidation and forms iron oxide (Fe2O3), which is commonly known as rust.

The heating of copper and iron in the presence of oxygen is an example of an exothermic reaction, which means that energy is released in the form of heat. In both cases, the metal atoms combine with oxygen atoms to form solid metal oxide compounds. This process is important in many industrial applications, including the production of metal alloys, and the prevention of corrosion in metals.
