$H_2O_2$ reduces $K_4[Fe(CN)_6]$ in which of the following conditions?

$(i)$ What mass of hydrogen peroxide will be present in $2 \, L$ of a $5 \, M$ solution?
$(ii)$ Calculate the mass of oxygen which will be liberated by the decomposition of $200 \, mL$ of this solution.

Three vessels $(A, B, C)$ contain $H_2O_2$ solution. In vessel $A$,$500 \ mL$ of $10 \ vol \ H_2O_2$ is present. $100 \ mL$ of $30 \ vol \ H_2O_2$ is present in vessel $B$. Vessel $C$ is filled with $250 \ mL$ of $2 \ M \ H_2O_2$. The weight (in $g$) of $H_2O_2$ present in these vessels follows the order:

The $pH$ of a solution of $H_2O_2$ is $6.0$. Some chlorine gas is bubbled into this solution. Which of the following is correct?

$(i)$ Draw the gas phase and solid phase structure of $H_2O_2$.
$(ii)$ $H_2O_2$ is a better oxidizing agent than water. Explain.

Which of the following statements is correct?
