Molecular equation

BaCO3 (s) + 2HBr (aq) - -> BaBr2 (aq) + CO2 (g) + H2O (l)

Ionic equation

BaCO3 (s) - -> Ba2 + (aq) + (CO3) 2 - (aq)

HBr (aq) - -> H + (aq) + Br - (aq)

Resultant ionic equation

Ba2 + (aq) + 2 Br - (aq) - -> BaBr2 (aq)

(CO3) 2 - (aq) + 2H + (aq) - -> H2O (l) + CO2 (g)

Explanation:

Molecular equation

BaCO3 (s) + 2HBr (aq) - -> BaBr2 (aq) + CO2 (g) + H2O (l)

Ionic equation

BaCO3 (s) - -> Ba2 + (aq) + (CO3) 2 - (aq)

HBr (aq) - -> H + (aq) + Br - (aq)

The anions bond with the cations ie the anions will give/share its outer electron while the cation accepts an electron/share its outer electron to form a stable octet in its shell a d hence a stable molecule

Ba2 + bonds with moles or Br - while (CO3) 2 - bonds with 2 moles of H + and form H2O and CO2 with is given off in effervescence.

Ba2 + (aq) + 2 Br - (aq) - -> BaBr2 (aq)

(CO3) 2 - (aq) + 2H + (aq) - -> H2O (l) + CO2 (g)
