3 Mg + 1 Fe2O3 →2 Fe + 3MgO
Type of Reaction: Single displacement.
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:
a. It turns color in the presence of an enzyme that us bound to the secondary antibody.
Explanation:
The compound chloronapthenel is used in the reaction because it changes the color in the presence of an enzyme. It is strong organic compound which is used in biochemical processes.
