Determine which class the substance belongs to that has the formula Na2O (small two). Name it. Write the equations of two chemical reactions that most clearly characterize its properties as a representative of the class you specified.
Na2O – sodium oxide – basic oxide. Interaction with acidic oxide or with acid are the most characteristic reactions for the basic oxide, which clearly demonstrate its basic properties.
1. Interaction with acidic oxide (carbon monoxide (IV)) to form a salt (sodium carbonate): Na2O + CO2 = Na2CO3.
2. Interaction with acid (hydrochloric acid) to form salt (sodium chloride) and water: Na2O + 2HCl = 2NaCl + H2O.
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.
