The sum of the coefficients in the abbreviated ionic reaction equation caco3 h2no3
September 30, 2021
Let us write the chemical equation for the interaction of calcium carbonate CaCO3 and nitric acid HNO3 in molecular form:
CaCO3 + 2HNO3 = Ca (NO3) 2 + H2O + CO2
Now we will rewrite the equation in molecular form in full and correspondingly abbreviated ionic forms:
CaCO3 + 2H (+) + 2NO3 (-) = Ca (2+) + 2NO3 (-) + H2O + CO2
CaCO3 + 2H (+) = Ca (2+) + H2O + CO2
Then the sum of the coefficients is 1 + 2 + 1 + 1 + 1 = 6
Answer: The sum of the coefficients in the abbreviated ionic equation for the reaction of salt and acid is 6.
