Question

CO2-H2CO3+ Mg(OH2) - x - CO2

Answer 1

Ответ:                                    MgCO3+H2O

Answer 2

Based on the chemical equation you provided, it appears to be incomplete or unbalanced. It is missing the products and the coefficients of the reactants and products.

To balance the equation, we need to determine the coefficients that will balance the number of atoms on both sides of the equation. Here's a possible balanced equation based on the given reactants:

CO2 + H2CO3 + Mg(OH)2 → MgCO3 + 2H2O

In this balanced equation, one molecule of carbon dioxide (CO2), one molecule of carbonic acid (H2CO3), and one molecule of magnesium hydroxide (Mg(OH)2) react to form one molecule of magnesium carbonate (MgCO3) and two molecules of water (H2O).

Note that the coefficient of Mg(OH)2 is 1 because there is only one magnesium ion and two hydroxide ions, which react with one molecule of carbon dioxide and one molecule of carbonic acid.
