The bond polarities of SiH₄ are polar. The molecular shape is tetrahedral. The molecule is nonpolar.
<h3>Explanation</h3>
As seen on the diagram, there are four Si-H bonds in a molecule of SiH₄. Electronegativity values:
The two atoms differ in electronegativity. As a result, the Si-H bond is polar.
There are four valence electrons in one Si atom. Each of the four electron will go to a Si-H bond. The Si atom in SiH₄ will have no lone pairs. The four Si-H bonds count towards four electron domains. As a result, the SiH₄ atom is tetrahedral.
Dipoles from each Si-H bond are equal. They are poised in a tetrahedral shape. As a result, their dipole balance each other. Overall, SiH₄ molecule will have no net dipole.
It's asking what are the conditions of the water when the three types of fishes overlap. the three kids of fishes overlap over in the middle which is D. mild temperatures, some suspended particles, flows at medium speed.
The answer is neutrons and protons.
Hope you got it!!
