(a)
Whether the reactionis “combination, decomposition, replacement, or ion exchange reactions.
(a)
Answer to Problem 5PEB
Solution:
Decomposition
Explanation of Solution
Introduction:
Ion exchange reaction: When ions of two different chemical compounds react with each other forming either aprecipitate, water or a gas, the reaction is known as an ion exchange reaction.
Decomposition: In this reaction the molecule decomposes into two or more different molecules.
Combination reaction: In this reaction two different molecules are combined to form a new molecule.
Replacement: In this type of reaction, one atom is replaced by another atom.
Explanation:
Recall the
Here, the molecule
Conclusion:
The reaction is a decomposition reaction as a molecule decomposesinto two molecules.
(b)
Whether the reaction is “combination, decomposition, replacement, or ion exchange reactions.
