Question

Складіть молекулярне, повне та скорочене йонні рівняння реакцій , які відповідають схемі. бфрій нітрат +? ⇒ барій сульфат + ?

Answer 1

Ba(NO3)2 + H2SO4= BaSO4 + 2HNO3

Answer 2

Molecular Equation:

The molecular equation for the reaction between barium nitrate (Ba(NO3)2) and sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and nitric acid (HNO3) is:

Ba(NO3)2 + H2SO4 → BaSO4 + 2HNO3 [[1]]

Complete Ionic Equation:

The complete ionic equation shows all the ions present in the reaction. In this case, the barium nitrate dissociates into barium ions (Ba2+) and nitrate ions (NO3-), while sulfuric acid dissociates into hydrogen ions (H+) and sulfate ions (SO4^2-):

Ba^2+ + 2NO3^- + 2H+ + SO4^2- → BaSO4 + 2H+ + 2NO3^- [[1]]

Net Ionic Equation:

The net ionic equation focuses only on the species that undergo a chemical change. In this case, the nitrate ions (NO3-) and hydrogen ions (H+) are spectator ions and do not participate in the reaction. Therefore, the net ionic equation is:

Ba^2+ + SO4^2- → BaSO4 [[1]]

This equation represents the essential chemical change that occurs during the reaction, which is the formation of barium sulfate from barium ions and sulfate ions.
