Question

a) Fe+ O2 + H2O =____
b) ____+ H2O =H2SO3
​

Answer 1

Answer:

Fe + O2 + H2O → Fe2O3

Iron + Oxygen + Water → Ferric Oxide

The above chemical reaction represents the chemical process named as rusting of iron. Rusting of iron refers to the accumulation of rust on the surface of iron materials which is a mixture of iron oxides. The rust is formed from a redox reaction between oxygen and iron in an environment containing water such as air containing high levels of moisture. The rusting of iron is characterized by the development of a layer of a red, flaky material that easily crumbles into a powder.
