Question

CO2 → H2CO3 → Na2CO3 → NaOH → Ba(OH)2 → BaSO4​

Answer 1

Ответ:

Объяснение:

CO2 + H2O → H2CO3

H2CO3 + 2 NaOH → 2 H2O + Na2CO3

Na2CO3 + 2 KOH  → 2 NaOH  + K2CO3

2 NaOH  + Ba(NO3)2  → 2 NaNO3  + Ba(OH)2

Ba(OH)2  + H2SO4  → 2 H2O + BaSO4

Answer 2

The sequence you've provided appears to be a series of chemical reactions involving different compounds. Let's break down each step:

1. CO2 (Carbon Dioxide): This is a gaseous compound consisting of one carbon atom bonded to two oxygen atoms, represented as CO2.

2. H2CO3 (Carbonic Acid): Carbon dioxide can dissolve in water to form carbonic acid (H2CO3), which can be written as H2O + CO2 ⇌ H2CO3. This is a weak acid.

3. Na2CO3 (Sodium Carbonate): Sodium carbonate is a salt of carbonic acid and consists of two sodium ions (Na+) and one carbonate ion (CO3^2-). It can be written as 2Na+ + CO3^2-.

4. NaOH (Sodium Hydroxide): Sodium hydroxide is a strong base consisting of sodium ions (Na+) and hydroxide ions (OH-). It can be written as Na+ + OH-.

5. Ba(OH)2 (Barium Hydroxide): Barium hydroxide is another strong base, containing barium ions (Ba^2+) and hydroxide ions (OH-). It can be written as Ba^2+ + 2OH-.

6. BaSO4 (Barium Sulfate): Barium sulfate is a compound formed when barium ions (Ba^2+) react with sulfate ions (SO4^2-). It can be written as Ba^2+ + SO4^2-.
