Write the molecular, complete and abbreviated ionic equations for the reactions between solutions: a) sulfuric acid and barium nitrate b) potassium carbonate and calcium chloride.
a) H2SO4 + Ba (NO3) 2 -> BaSO4 + 2HNO3
2H + + SO42- + Ba2 + + 2NO3- -> BaSO4 + 2H + + 2NO3- – complete ionic equation;
Ba2 + + SO42- -> BaSO4 is an abbreviated ionic equation.
b) K2CO3 + CaCl2 -> 2KCl + CaCO3
2K + CO32- + Ca + 2Cl -> 2K + 2Cl + CaCO3 – complete ionic equation;
CO32- + Ca -> CaCO3 is an abbreviated ionic equation.
In the abbreviated ionic equation, only the product is written that does not dissociate further (released as a gas, precipitates) or weakly dissociates (water) and the reagents that formed it
