Answer:
A. Dry with low humidity
Explanation:
Atmosphere is the layer of gases that surrounds the earth above air layer. Its conditions affect our climate.
The hydrosphere includes the water which is on the surface of the earth,below the ground and in the air.
Tropics are the region of our earth surrounding the equator.
On analyzing the climatic conditions in the tropics due to the interaction of the atmosphere and hydrosphere, the presence of water droplets in tropics is less resulting in less humidity and, thus the climatic condition is dry.
Therefore the climatic condition that is typically found in tropics due to interaction of the atmosphere and hydrosphere is dry with low humidity.
This is true, vapor is just evaporated water. Like in machines, you have to fill it up with water so your machine can produce the water vapor. Hope this helps!!
2.11x10^24 Ca atoms
In order to find the amount of atoms we must use Avogadro’s number, 6.022 x 10^23
Since we have moles, 3.5 the equation would look like this
3.5 moles Ca x 6.022x10^23/1 = 2.1077 x 10^24, which we round to 2.11 x 10^24 atoms of Ca
