net ionic equations

What is a net ionic equation?

• A net ionic equation shows all ions present in a solution.

• A net ionic equation shows only the species that participate in a chemical reaction, omitting the spectator ions.

• A net ionic equation is a type of chemical equation that includes all reactants and products.

• A net ionic equation is used to balance chemical equations without considering the charges.

What is a synthesis reaction?

• A reaction where a single reactant breaks down into two or more products.

• A type of reaction where two or more reactants combine to form a single product.

• A reaction that involves the exchange of ions between two compounds.

• A process where energy is absorbed without any chemical change.

What is the net ionic equation for the reaction of AgNO₃ and CaCl₂?

• Ag⁺(aq) + Cl^-(aq) → AgCl(s)

• Ag⁺(aq) + Ca²⁺(aq) → AgCa(s)

• Ca²⁺(aq) + 2Cl^-(aq) → CaCl₂(s)

• Ag⁺(aq) + 2Cl^-(aq) → AgCl₂(s)

What is the difference between soluble and insoluble compounds?

• Soluble compounds dissolve in water, while insoluble compounds do not.

• Soluble compounds are always solid, while insoluble compounds are always liquid.

• Soluble compounds can be separated by filtration, while insoluble compounds cannot.

• Soluble compounds react with acids, while insoluble compounds do not.

What is the general form of a double displacement reaction?

• AB + CD → AD + CB, where A and C are cations and B and D are anions.

• AB + CD → AC + BD, where A and B are cations and C and D are anions.

• AB + CD → AC + DB, where A and D are cations and B and C are anions.

• A + B → AB, where A and B are elements.

What is the balanced equation for the reaction of iron and oxygen? (assume iron will form a +3 charge)

• 3Fe + 2O₂ → Fe₃O₂

• 4Fe + 3O₂ → 2Fe₂O₃.

• 2Fe + O₂ → Fe₂O₃

• K₂CO₃ is soluble in alcohol.

How do you identify a net ionic equation from a complete ionic equation?

• Add more ions to the complete ionic equation.

• Remove the spectator ions from the complete ionic equation to obtain the net ionic equation.

• Combine all ions into one equation without any changes.

• Identify the states of matter for each ion in the equation.
