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.
The answer is A. Bowen's Reaction Series.
<span>Minerals form from magma in the predictable patterns in a process known as Bowen's Reaction Series.</span>
In addition to the elements enhancing structural rigidity, these latter compounds contain three new chiral centers.
0.53313648 feet = 16.25cm
<span>Well, for one, they have the same amount of electrons in the outmost shell: Group 1 has 1, Group 2 has 2 etc...They all share similar chemical properties, for example Group 6 (?) S and Se both are acidic oxides.</span>
