- D.
D
- E.
E
- F.
F
Correct Answer
D. DExplanation
The correct answer is d. In the given options, only option d is a tetrahedral shape. A tetrahedron is a three-dimensional shape with four triangular faces, six edges, and four vertices. Option d represents a tetrahedron as it has four triangular faces meeting at a common vertex.Rate this question:

- A.
A
- B.
B
- C.
C
- D.
D
- E.
E
- F.
F
Correct Answer
C. CExplanation
linear means straight line. this shape forms a straight line, there for its LINEAR. because of the number of atoms it has, it makes it TRIatomic, (Tri is a prefix for three)Rate this question:

- 9.
Which of the following is true about C.? Check all the boxes that apply. A. B. C. D. E. F.
- A.
Its angle is 180*
- B.
CO2, H2O, and Na2S are examples of this
- C.
It involves 3 atoms
- D.
Its called linear triatomic
- E.
This shape says the molecule is polar
Correct Answer(s)
A. Its angle is 180*
C. It involves 3 atoms
D. Its called linear triatomicExplanation
H2O is a bent triatomic shape, and this shape is NOT polar because the two opposing atoms are canceling one another's polarity out.Rate this question:
