<u>Answer:</u>
<u>For 1:</u> The correct answer is False.
<u>For 2:</u> The correct answer is True.
<u>For 3:</u> The correct answer is True.
<u>For 4:</u> The correct answer is False.
<u>For 5:</u> The correct answer is True.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions. If no net ionic equation is formed, it is said that no reaction has occurred.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form. Solids, liquids and gases do not exist as ions.
- <u>For 1:</u> Lead(II) nitrate and sodium chloride
The chemical equation for the reaction of lead (II) nitrate and sodium chloride is given as:
Ionic form of the above equation follows:
As, sodium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the correct answer is False.
- <u>For 2:</u> Sodium bromide and hydrochloric acid
The chemical equation for the reaction of sodium bromide and hydrochloric acid is given as:
Ionic form of the above equation follows:
There are no spectator ions in the equation. So, the above reaction is the net ionic equation.
Hence, the correct answer is True.

The net ionic equation for the above reaction follows:
Hence, the correct answer is True.
- <u>For 4:</u> Magnesium chloride and sodium hydroxide
The chemical equation for the reaction of magnesium chloride and sodium hydroxide is given as:
Ionic form of the above equation follows:
As, sodium and chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the correct answer is False.
- <u>For 5:</u> Ammonium sulfate and barium nitrate
The chemical equation for the reaction of ammonium sulfate and barium nitrate is given as:
