Answer 1

СО2+Na2O=Na2CO3 - реакция присоединения

Answer 2

CO2+Na2O = Na2CO3 ; Углекислый газ + оксид натрия = карбонат натрия.

Answer 3

CO2 and Na2O are chemical compounds with different properties and uses.

Carbon Dioxide (CO2)

Carbon dioxide (CO2) is a colorless and odorless gas composed of one carbon atom bonded to two oxygen atoms. It is a naturally occurring compound and is essential for life on Earth. Here are some key points about CO2:

- Chemical Formula: CO2 - Molecular Weight: 44.01 grams per mole - Physical Properties: Carbon dioxide is a gas at room temperature and atmospheric pressure. It is denser than air and can be liquefied under high pressure and low temperature. - Sources: CO2 is produced through various natural and human activities, including respiration, combustion of fossil fuels, and industrial processes. - Role in the Environment: Carbon dioxide is a greenhouse gas that plays a crucial role in regulating Earth's temperature. However, excessive CO2 emissions contribute to global warming and climate change. - Uses: CO2 has various applications, including carbonation of beverages, fire extinguishers, and as a solvent in some industrial processes.

Sodium Oxide (Na2O)

Sodium oxide (Na2O) is an inorganic compound composed of two sodium (Na) atoms bonded to one oxygen (O) atom. Here are some key points about Na2O:

- Chemical Formula: Na2O - Molecular Weight: 61.98 grams per mole - Physical Properties: Sodium oxide is a white crystalline solid at room temperature. It has a high melting point and is highly reactive with water. - Sources: Sodium oxide can be produced by the reaction of sodium metal with oxygen gas or by the decomposition of sodium peroxide. - Role in Chemistry: Sodium oxide is a basic oxide and reacts with water to form sodium hydroxide (NaOH), a strong alkali. - Uses: Sodium oxide is used in the production of glass, ceramics, and as a desiccant (drying agent). It is also used in some chemical reactions and as a catalyst in certain industrial processes.

In summary, carbon dioxide (CO2) is a gas that is essential for life on Earth but can contribute to climate change when emitted in excess. Sodium oxide (Na2O) is a solid compound used in the production of glass, ceramics, and as a desiccant.
