We are given substances, H2SO3 – sulfurous acid, NaOH – base sodium hydroxide, Fe (OH) 2 – base, trivalent iron hydroxide. We need to write the formulas of the corresponding oxides to the hydroxides. We will not write an oxide for sulfurous acid, which we will not write, since it does not belong to the class of hydroxides, although it is formed by an acidic oxide.

Sodium hydroxide corresponds to bivalent sodium oxide, which has the chemical formula – Na2O. Trivalent iron hydroxide corresponds to trivalent iron oxide – Fe2O3.

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.
