Question

Write a net ionic equation for the reaction that occurs when excess hydroiodic acid and barium carbonate (s) are combined.

Answer 1

The balanced chemical equation for the reaction between excess hydroiodic acid and barium carbonate is 2HI + BaCO3 → BaI2 + CO2 + H2O, and the net ionic equation is 2H+ + CO32- → CO2 + H2O.

Step-by-step explanation:

The balanced chemical equation for the reaction between excess hydroiodic acid and barium carbonate (s) is:

2HI + BaCO3 → BaI2 + CO2 + H2O

To write the net ionic equation, we need to identify the species that are actually involved in the chemical reaction. The net ionic equation for this reaction is:

2H+ + CO32- → CO2 + H2O

The primary topic of this question is the writing of net ionic equations for chemical reactions.
