(i) Write the equation of the system of circles having the line of centres as $\mathrm{y}$ -axis and radical axis as the $\mathrm{x}$ -axis. (ii) Find the differential equation of above system.
When a $6.50-\mathrm{g}$ sample of solid sodium hydroxide dissolves in $100.0 \mathrm{~g}$ of water in a coffee-cup calorimeter (Figure 5.18 ), the temperature rises from $21.6^{\circ} \mathrm{C}$ to $37.8^{\circ} \mathrm{C}$. Calculate $\Delta H$ (in $\mathrm{kJ} / \mathrm{mol} \mathrm{NaOH})$ for the solution process $$ \mathrm{NaOH}(s) \longrightarrow \mathrm{Na}^{+}(a q)+\mathrm{OH}^{-}(a q) $$ Assume that the specific heat of the solution is the same as that of pure water.
