Write the oxide formulas that correspond to the hydroxides: H2SO3, Be (OH) 2.

H2SO3 – sulfurous acid. The corresponding oxide is SO2. (The reaction equation for producing sulfurous acid from oxide: SO2 + H2O = H2SO3).
Be (OH) 2 – beryllium hydroxide. Corresponding oxide: BeO. (The reaction equation for obtaining beryllium hydroxide from oxide: BeO + H2O = Be (OH) 2).



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.
