<u>Answer:</u> The net ionic equation is written below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
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.
The chemical equation for the reaction of ammonium carbonate and lead (II) nitrate is given as:
Ionic form of the above equation follows:
As, ammonium 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 net ionic equation is written above.
Answer:
For 1: The correct answer is false.
For 2: The correct answer is , because K retains the same charge throughout the reaction.
For 3: The correct answer is
For 4: The correct answer is a single replacement reaction takes place because sodium is more reactive than hydrogen.
For 5: The correct answer is False.
For 6: The correct answer is it is a single replacement reaction, and the cations in the two ionic compounds are different.
Explanation:
- <u>For 1: </u>
This type or reaction is based on the reactivity series. If the metal which lies above in the series will replace the metal which lies below in the series easily.
From the reactivity table attached below, we know that lead lies below in the series to Aluminium and hence, it will not replace in the reaction.
Hence, the correct answer is False.
- <u>For 2: </u>
A balanced equation is defined as the equation in which there are same number of atoms present on the reactant side and the product side.
The balanced equation always follow Law of Conservation of Mass.
So, from the given options, the below equation is the balanced equation because K retains the same charge throughout the reaction.
- <u>For 3:</u>
A single displacement reaction is a type of chemical reaction in which one element replaces another element in a chemical reaction. The element which is more reactive will replace the less less reactive element.
This is explained by reactivity series as the metal which lies above in the series will replace the metal which lies below in the series easily. From the given equations, the equation which is a type of single displacement reaction is:
: This equation is a type of double displacement reaction.
: This equation is a type of combination reaction.
: This equation is a type of combination reaction.
- <u>For 4:</u>
A single displacement reaction is a type of chemical reaction in which one element replaces another element in a chemical reaction.
A double displacement reaction is a type of chemical reaction in which exchange of ins takes place.
In the question, it is asked that sodium metal is reacting with water to produce hydrogen gas and sodium hydroxide. This reaction is a type of single displacement reaction because sodium is more reactive than hydrogen as shown in the reactivity series.
- <u>For 5: </u>
A single displacement reaction is a type of chemical reaction in which one element replaces another element in a chemical reaction. This reaction will not follow when an element replaces similar element.
Hence, the statement is False.
- <u>For 6:</u>
For the reaction:
It is a type single replacement reaction as the cations in the two ionic compounds are different.
For Example:
Where, Sodium and Aluminium are the cations and chlorine is an anion.
