Question

Mg(OH)2 + _____ = MgCO3 + H2O
balance it and fill it.​

Answer 1

Explanation:

This is an acid-base reaction (neutralization): H 2CO 3 is an acid, Mg(OH) 2 is a base. , [Note: Magnesite is a naturally-occurring form of magnesium carbonate.]

1) Mg(HCO3)2 → H2O + CO2 + MgCO3

5) O2 + Mg(OH)2 + C9H8O4 → H2O + CO2 + MgCO3

6) MgO + H2CO3 → H2O + MgCO3

Answer 2

Answer:

Mg(OH)2 + H2CO3 forms MgCO3 + 2H2O.
