Write a balanced equation to show the reaction of sulfurous acid with lithium hydroxide to form water and lithium sulfite.

How to write the balanced equation for the reaction between (NH$_4$)$_2$SO$_4$ and KOH?

A $200 \times 250-\mathrm{mm}$ panel of mass $20 \mathrm{~kg}$ is supported by hinges along edge $A B$. Cable $C D E$ is attached to the panel at $C$, passes over a small pulley at $D$, and supports a cylinder of mass $m$. Neglecting the effect of friction, write a computer program that can be used to calculate the mass of the cylinder corresponding to equilibrium for values of $\theta$ from 0 to $90^{\circ}$ using $10^{\circ}$ increments. Using appropriate smaller increments, determine the value of $\theta$ corresponding to $m=10 \mathrm{~kg}$.
