Question

Завершите приведенные уравнения KOH+CO2-> .... MgO+Co2-> ... Na2CO3+H2O+CO2-> ....

Answer 1

1. = KHCO3
2. = MgCO3
3. Будет тоже самое, т.к. Н2О и СО2 это угольная кислота: Н2СО3. После взаимодействия с Na будет то же самое.

Answer 2

Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that the same number of each type of atom is present on both sides of the equation.

1. KOH + CO2 -> ... Potassium hydroxide (KOH) reacts with carbon dioxide (CO2) to form potassium carbonate (K2CO3) and water (H2O).

The balanced equation is: ``` 2KOH + CO2 -> K2CO3 + H2O ```

This equation ensures that there are equal numbers of each type of atom on both sides of the equation [[1]].

2. MgO + CO2 -> ...

Magnesium oxide (MgO) reacts with carbon dioxide (CO2) to form magnesium carbonate (MgCO3).

The balanced equation is: ``` MgO + CO2 -> MgCO3 ```

This equation ensures that there are equal numbers of each type of atom on both sides of the equation [[2]].

3. Na2CO3 + H2O + CO2 -> ...

Sodium carbonate (Na2CO3) reacts with water (H2O) and carbon dioxide (CO2) to form sodium bicarbonate (NaHCO3).

The balanced equation is: ``` Na2CO3 + H2O + CO2 -> 2NaHCO3 ```

This equation ensures that there are equal numbers of each type of atom on both sides of the equation [[3]].
