The calorimeter burns the object and tells how many calories are generated when the object is burned.
Answer:
Group 17, 2, 7, 7 electrons
Explanation:
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.
