The main purpose of these hydrogen-filled balloons to detect movements of enemy troops and to provide direction to the artillery fire. Balloons were the targets of opposing aircraft because they knew the purpose of these balloons so they hit it whenever seen by the enemies so we can say that both sides used hydrogen-filled balloons as military observer to watch the enemy's movements.

I believe that the property referenced in 'like dissolves like" is polarity. Solvents are substances that dissolves solutes forming a solution. Solvents may be either polar or non polar; polar solvents contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen, while non polar solvents have bonds between atoms with similar electronegativities such as hydrogen and carbon.
I believe it’s 23 as there are 23 individual atoms present in this compound.
