Select the chemical equation that most likely represents the reaction between the vinegar and the dolomite.

Respuesta :

B. MgCO3 + 2HCH3COO -----> Mg(CH3COO)2 + CO2 + H2O

Answer: The reaction is given below.

Explanation:

Dolomite is a carbonate ore of calcium and magnesium. Its chemical formula is [tex]CaMg(CO_3)_2[/tex].

Another name of vinegar is acetic acid and its chemical formula is [tex]CH_3COOH[/tex]

The reaction between vinegar and dolomite follows the equation:

[tex]4CH_3COOH+CaMg(CO_3)_2\rightarrow Ca(CH_3COO)_2+Mg(CH_3COO)_2+2CO_2+H_2O[/tex]

By Stoichiometry of the reaction:

4 moles of acetic acid reacts with 1 mole of dolomite to produce 1 mole of calcium acetate, 1 mole of magnesium acetate, 2 moles of carbon dioxide and 1 mole of water.
