1 mole = 70.9
X mole = 140
X=1.9746 moles
X= 1.98 when rounded to 3 significant figures.
Answer: E. trigonal planar
Explanation:
The trigonal planar geometry is made up of 3 equally spaced sp2 hybrid orbitals arranged at angle 120° to each other, The molecule are electron deficient and does not follow octet rule. Therefore, a molecule containing an sp2 hybrid central atom has a trigonal planar geometry e.g boron hydride (BH3)
At a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.
<h3>
Behavior of gases at low pressure and high pressures</h3>
At low pressure, the distance between gas molecules is relatively far apart, but as the pressure of the gas increases, the distances between theses gaseous molecules becomes smaller.
Due to the high pressure the volume occupied by the gas molecules becomes significant compared with the volume of the container.
As a result, the total volume occupied by the gas will be greater than the volume predicted by the ideal gas law.
Thus at a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.

Answer:
it will float back up because it's not dense enough to go down
Answer:
Explanation:
All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area.
