Answer: The correct option is C) decomposition
Explanation:
Single displacement reaction is defined as the reaction where a more reactive element displaces a less reactive element from its salt solution.
[tex]AX+B\rightarrow BX+A[/tex]
Element B is more reactive than element A
Double displacement reaction is defined as the reaction where an exchange of ions takes place in a solution
[tex]AX+BY\rightarrow AY+BX[/tex]
Decomposition reaction is defined as the reaction where a single large chemical species breaks down into two or more smaller chemical species.
[tex]AB\rightarrow A+B[/tex]
Synthesis reaction is defined as the reaction where two or more smaller chemical species combine together in their elemental state to form a single large chemical species.
[tex]A+B\rightarrow AB[/tex]
For the given chemical reaction:
[tex]2H_2O(l)\rightarrow 2H_2(g)+O_2(g)[/tex]
Here, water is breaking down into two smaller species of oxygen and hydrogen gas. Thus, it is a decomposition reaction.
Hence, the correct option is C) decomposition
