The picture below shows a NASA image of the Oort cloud, a sphere of objects that are thought to surround Earth's solar system at
a distance of up to one light-year from the Sun. If the Oort cloud does exist, which of the following could explain why the objects in it may have formed this spherical shape?
A
They are held in orbits by the Sun's gravitational force.
B
They are held in Earth's solar system by Neptune's magnetic field.
C
They float freely in space because the Sun's gravitational force is too weak to hold them in orbit.
D
They are held in stationary positions around Earth's solar system by other stars in space.
The strong base will be dissociated completely into the aqueous solution. The pOH of the solution can be determined by the concentration of the hydroxide ion. The strong bases have lower pOH value.
