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.
Answer : The density of an object is 0.93 g/mL
Explanation : Given,
Mass of an object = 3.8 g
Initial volume = 4.5 mL
Final volume = 8.6 mL
First we have to calculate the volume of an object.
Volume of an object = Final volume - Initial volume
Volume of an object = 8.6 mL - 4.5 mL
Volume of an object = 4.1 mL
Now we have to calculate the density of an object.
Formula used:
Now putting all the given values in this formula, we get:
Therefore, the density of an object is 0.93 g/mL
