$O_2$ is formed in the hydrolysis of:

The correct order of acidic strength is

Which of the following is the strongest acid?

Given below are two statements: Statement $(I)$: Oxidising power of halogens decreases in the order $F_2 > Cl_2 > Br_2 > I_2$, which is the basis of "Layer test". Statement $(II)$: "Layer test" to identify $Br_2$ and $I_2$ in aqueous solution involves the oxidation of bromide or iodide into $Br_2$ or $I_2$ respectively with $Cl_2$, which is a type of displacement redox reaction. In the light of the above statements, choose the correct answer from the options given below:

The hydrolysis products of the $BrF_5$ molecule are given by the reaction: $BrF_5 + 3H_2O \rightarrow HBrO_3 + 5HF$. What are the products of this reaction?
