Give answer
For the given redox reaction, what will be the sum of $x, y, m$ and $n$ ?
$$\begin{aligned} x \mathrm{MnO}_4^{-}+y \mathrm{H}_2 \mathrm{C}_2 \mathrm{O}_4+z \mathrm{H}^{+} \longrightarrow m \mathrm{Mn}^{2+} + & n \mathrm{CO}_2+p \mathrm{H}_2 \mathrm{O} \end{aligned}$$
The bond dissociation energies for $\mathrm{Cl}_2, \mathrm{I}_2$ and ICl are $242.3,151.0$ and $211.3 \mathrm{~kJ} / \mathrm{mol}$ respectively. The enthalpy of sublimation of iodine is $62.8 \mathrm{~kJ} / \mathrm{mol}$. What is the standard enthalpy of formation of $\operatorname{ICl}(\mathrm{g})$ nearly equal to?
The boiling points of 0.01 M aqueous solution of sucrose, NaCl and $\mathrm{CaCl}_2$ would be
