Answer : The products are Silver sulfide, and Sodium iodide,
.
Explanation :
The given balanced chemical reaction is,
From the given balanced reaction, we conclude that the 2 moles of silver iodide react with the 1 mole of sodium sulfide to give product as 1 mole of silver sulfide and 2 moles of sodium iodide.
In a chemical reaction, reactants are represent on the left side of the right-arrow and products are represent on the right side of the right-arrow.
Therefore, in a chemical reaction the products are Silver sulfide and Sodium iodide.
Answer: The correct option is Aluminium.
Explanation: To recover copper from the solution, we require a metal which can easily displace copper from the solution.
The reactions in which metal displaces another metal in a chemical reaction are known as single displacement reactions. These reactions are studied using reactivity series.
A is more reactive than B.
The metal which lie above in the reactivity series will easily displace the metal which lies below in the reactivity series.
From the given options, Aluminium is the most reactive of all the metals and hence, it is the best choice for recovering copper from its solution.
