2. Which of the following is/are TRUE regarding net ionic equations?

A. Net ionic equations show only the particles directly involved in the
chemical change.
B. Spectator ions are included in complete equations, but not in net ionic
equations.
C. lonic charges do not need to be balanced in a net ionic equation.
D. Combustion, combination, and decomposition reactions can be written as
net ionic equations.

Respuesta :

A and B are true.

C and D are false.

Out of the given four statements, A and B are only correct.

Explanation:

  • In the complete equation of a chemical reaction, the complete symbols of reactants and products are written along with states of matter under conditions at which the reaction is taking place.
  • In the net ionic equation of a chemical reaction, only those chemical species are written which directly participating in the chemical reaction.
  • The mass and charge in the net ion equation must be balanced
  • It is used in neutralization reactions, redox reactions, double displacement reactions.

So from this, we can conclude that out of the given four statements, A and B are only correct.
