Net Ionic Equations and Ammonia

The video tutorial explains how to write a balanced net ionic equation for the reaction between ammonia (NH3) and hydrobromic acid (HBr). It begins with balancing the molecular equation and assigning states to each substance. The tutorial then covers splitting strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The video also discusses ammonia's reaction with water to form ammonium hydroxide and how this affects the net ionic equation.

What is the first step in writing a net ionic equation?

• Split strong electrolytes into ions

• Balance the molecular equation

• Identify spectator ions

• Write the states of substances

Which of the following is true about hydrobromic acid in the reaction?

• It is a strong electrolyte

• It does not dissociate in water

• It is a weak acid

• It forms a precipitate

Why is ammonia not split into ions in the complete ionic equation?

• It is a non-electrolyte

• It forms a precipitate

• It is a weak electrolyte

• It is a strong base

What is the role of spectator ions in a net ionic equation?

• They participate in the reaction

• They form new compounds

• They are removed from the equation

• They change the charge balance

Which ion is considered a spectator ion in the reaction between NH3 and HBr?

• Bromide ion

• Hydroxide ion

• Hydrogen ion

• Ammonium ion

What is conserved in a balanced net ionic equation?

• Both mass and charge

• Only charge

• Neither mass nor charge

• Only mass

What happens when ammonia is dissolved in water?

• It becomes a strong acid

• It forms a precipitate

• It remains unchanged

• It forms ammonium hydroxide

What is the chemical formula for ammonium hydroxide?

• NH4Cl

• NH4OH
