Answer:

C. tetrahedron

Explanation:

Silicon tetrabromide (SiBr₄)

Valence electrons of silicon = 4

Valence electrons of bromine = 7  

The total number of the valence electrons  = 4 + 4(7) = 32

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,  the lewis structure is shown in the image below.

Around the central metal atom:-

Number of bond pairs = 4

Number of lone pairs = 0

The formula is AB_4.

<u>According to VSEPR theory, silicon tetrabromide has tetrahedron shape to minimize the repulsions. </u>

A _____ exists in the same physical state as that of the reaction it catalyzes.

<span>A Homogeneous Catalyst exists in the same physical state as that of the reaction it catalyzes.

Explanation:
                     
Catalysts are classifies as follow,
                                                      1. Homogeneous Catalyst
                                                      2. Heterogeneous Catalyst

</span>Homogeneous Catalyst are those which are in same phase as that of reactants are.

Example:

         Acetic Acid + Ethanol + H₂SO₄  →  Ethyl Acetate + H₂O + H₂SO₄

In this reaction catalyst and reactants all are in same phase i.e. Liquids.

Heterogeneous Catalyst are those which are in different phase as that of reactants are.

Example:

                                 Ethene + H₂ + Ni  →  Ethane + Ni

In this reaction ethene and hydrogen are gases while Nickle catalyst is in solid state.
