Question

Решите химию 8 класс , пж. 15 баллов!!! Оксид углерода H20 , Li20, KOH Оксид азота Н20, KOH , Na20 Написать реакции!

Answer 1

Ответ:

Объяснение:

CO2 + H2O =H2CO3

CO2 + Li2O = Li2CO3

CO2 + 2KOH = K2CO3 + H2O

N2O5 + H2O = 2HNO3

N2O5 + 2KOH = 2KNO3 + H2O

N2O5 + Na2O = 2NaNO3

Оксид углерода H2O, Li2O, KOH Оксид азота H2O, KOH, Na2O Написать реакции!

Оксид углерода (II) CO — это несолеобразующий оксид, который не реагирует с водой H2O, оксидом лития Li2O и гидроксидом калия KOH. Поэтому эти реакции не протекают:

CO + H2O -> нет реакции CO + Li2O -> нет реакции CO + KOH -> нет реакции

Оксид азота (II) NO — это кислотный оксид, который реагирует с водой H2O, образуя слабую кислоту — азотистую кислоту HNO2:

NO + H2O -> HNO2

Оксид азота (II) также реагирует с основными оксидами, такими как оксид натрия Na2O и оксид лития Li2O, образуя соли — азотиты:

NO + Na2O -> NaNO2 NO + Li2O -> LiNO2

Оксид азота (II) также реагирует с щелочами, такими как гидроксид калия KOH, образуя также азотиты:

NO + KOH -> KNO2

Надеюсь, это поможет вам с вашим заданием. Удачи!

Reactions of Carbon Monoxide (CO), Water (H2O), Lithium Oxide (Li2O), Potassium Hydroxide (KOH), Nitric Oxide (NO), and Sodium Oxide (Na2O)

1. Carbon Monoxide (CO): - Carbon monoxide is a colorless, odorless gas that is produced by the incomplete combustion of carbon-containing substances. - The chemical formula for carbon monoxide is CO. - Carbon monoxide can react with oxygen to form carbon dioxide (CO2): ``` 2CO + O2 -> 2CO2 ```

2. Water (H2O): - Water is a compound made up of two hydrogen atoms bonded to one oxygen atom. - The chemical formula for water is H2O. - Water can act as both an acid and a base, depending on the reaction it is involved in. - Water can react with certain metal oxides to form metal hydroxides: - Reaction with lithium oxide (Li2O): ``` Li2O + H2O -> 2LiOH ``` - Reaction with potassium hydroxide (KOH): ``` KOH + H2O -> K+ + OH- + H2O ```

3. Lithium Oxide (Li2O): - Lithium oxide is an inorganic compound composed of lithium and oxygen. - The chemical formula for lithium oxide is Li2O. - Lithium oxide can react with water to form lithium hydroxide: ``` Li2O + H2O -> 2LiOH ```

4. Potassium Hydroxide (KOH): - Potassium hydroxide is an inorganic compound that is commonly known as caustic potash. - The chemical formula for potassium hydroxide is KOH. - Potassium hydroxide can react with water to form potassium ions (K+) and hydroxide ions (OH-): ``` KOH + H2O -> K+ + OH- + H2O ```

5. Nitric Oxide (NO): - Nitric oxide is a colorless gas that is produced during the combustion of fossil fuels. - The chemical formula for nitric oxide is NO. - Nitric oxide can react with potassium hydroxide to form potassium nitrate (KNO3): ``` 2NO + 2KOH -> KNO3 + H2O ```

6. Sodium Oxide (Na2O): - Sodium oxide is an inorganic compound composed of sodium and oxygen. - The chemical formula for sodium oxide is Na2O. - Sodium oxide can react with water to form sodium hydroxide: ``` Na2O + H2O -> 2NaOH ```
