Explanation:
It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.
Therefore, in one simple cubic unit cell sharing of one atom is only 
.
Hence, the total number of atoms in a unit cell will be as follows.
= 1
Thus, we can conclude that there is 1 calcium atom present in each unit cell.
The layer of Earth that has partially melted material that moves the tectonic plates is Mantle. The correct option is C.
<h3>What are the layers of the Earth?</h3>
The Earth is divided into three layers: the crust, the mantle, and the core. This is the earth's outer layer, and it is composed primarily of solid rock, primarily basalt and granite. Oceanic crust and continental crust are the two types of crust.
The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.
Thus, the correct option is C.

Answer:
trigonal planar
Explanation:
The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.
There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle. The bond angle is 120 degrees.
