Quizplus · Accepted Answer

The balanced net ionic equation is obtained by writing the balanced molecular equation and then canceling out the spectator ions (ions that appear on both sides and do not participate in the reaction). The balanced molecular equation for the reaction is:

Na2B12S13 + 2HCl -> 2NaCl + H2S + CO2

The balanced net ionic equation is:

Na2B12S13 + 2H+ -> 2Na+ + H2S

In this equation, H+ and H2S are the only species that actually participate in the reaction, while Na+ and Cl- are spectator ions. Choice C correctly represents the balanced net ionic equation for the reaction by omitting the spectator ions. Choices A, B, and D either include spectator ions or have incorrect stoichiometric coefficients.
