What substances does iron react with?

When hot iron interacts with water, an oxidative reaction occurs, as a result of which a basic oxide is formed. The results of the interaction will depend on the proportions of the components – if you take 4 moles of water and 3 moles of iron, you get hydrogen (a gas with a harsh odor) and iron slag.
The reaction of iron with salts and acids is also carried out. Iron causes hydrogen from compounds by a displacement reaction. You can observe this by adding acid to the iron. For example, when you mix dilute sulfuric acid and iron in the same molar proportions, hydrogen and ferrous sulfate are formed in the same molar proportions.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
