question 1 of 10
how is a net ionic equation written from a complete ionic equation?

a. the ions are combined to form compounds.

b. the spectator ions are removed.

c. all ions are removed from the equation.

d. the (aq) state symbols are removed.

Explanation:

To determine how a net ionic equation is written from a complete ionic equation, we analyze each option:

• Option A: Combining ions to form compounds is part of writing chemical equations but not the specific step for net ionic from complete ionic.
• Option B: Spectator ions are ions that appear unchanged on both sides of a complete ionic equation. Removing them (since they do not participate in the reaction) gives the net ionic equation. This matches the definition.
• Option C: Removing all ions would leave no equation, which is incorrect.
• Option D: Removing (aq) state symbols does not relate to deriving the net ionic equation.

Answer:

B. The spectator ions are removed.
