Question

Mg(OH)2=X=MgCO3=CO2=K2CO3

Answer 1

-  Mg(OH)2 + CO2 = MgCO3 + H2O

- MgCO3 -> MgO + CO2

- CO2 + 2KOH = K2CO3 + H2O

 

Answer 2

Mg(OH)2=X=MgCO3=CO2=K2CO3

Пусть Х - MgO

Mg(OH)2 = (t над равно) MgO + H2O

MgO + CO2 = MgCO3

MgCO3 = (t над равно) MgO + CO2 (стрелка вверх)

K2O + CO2 = K2CO3

Answer 3

Chemical Reaction Analysis

The given chemical equation seems to be a series of reactions involving Mg(OH)2, MgCO3, CO2, and K2CO3. Let's break it down step by step.

Step 1: The first part of the equation seems to be a decomposition reaction of Mg(OH)2: 2 Mg(OH)2 → 2 MgO + 2 H2O + CO2

This is based on the reaction of 2 Mg + O2 + 2 H2O = 2 Mg(OH)2 [[1]](https://elar.urfu.ru/bitstream/10995/40625/1/978-5-7996-1780-6_2016.pdf).

Step 2: The next part involves the reaction of CO2 with K2CO3: K2CO3 + CO2 + H2O → 2 KHCO3

This is based on the reaction: CO2: K2CO3 + CO2 + H2O → 2 KHCO3 [[8]](https://www.trims.edu.az/noduploads/book/quot-himiya-quot-kimya-fanni-uzra-9-cu-sinif-ucun-darslik-1597225611-433.pdf).

Step 3: The formation of MgCO3 from MgO and CO2: MgO + CO2 + H2O → MgCO3

This is based on the reaction: MgCO3 + CO2 + H2O → Mg(HCO3)2 [[8]](https://www.trims.edu.az/noduploads/book/quot-himiya-quot-kimya-fanni-uzra-9-cu-sinif-ucun-darslik-1597225611-433.pdf).

Conclusion: Based on the provided information, the chemical equation seems to represent a series of reactions involving the decomposition of Mg(OH)2 to form MgO, H2O, and CO2, followed by the reaction of CO2 with K2CO3 to form KHCO3, and the formation of MgCO3 from MgO and CO2.
