    Which of the following will water have?A.         B.         C. - ProProfs

    Which of the following will water have?A.         B.         C.

    • A

    • B

    • C

    Correct Answer
    A. B
    Explanation
    the H2O (water) molecule is bent because the two unshared pairs of electrons on oxygen repel the bonding electrons.

    Which of the following is LINEAR TRIATOMIC?A.         B.         C. D.               E.           F. - ProProfs

    Which of the following is LINEAR TRIATOMIC?A.         B.         C. D.               E.           F.

    • A

    • B

    • C

    • D

    • E

    • F

    Correct Answer
    A. C
    Explanation
    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)

  • 5. 
    Which of the following is a TETRAHEDRAL?A.         B.         C. D.               E.           F. - ProProfs

    Which of the following is a TETRAHEDRAL?A.         B.         C. D.               E.           F.

    • A

    • B

    • C

    • D

    • E

    • F

    Correct Answer
    A. D
    Explanation
    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.

    • A

    • B

    • C

    Correct Answer
    A. C
    Explanation
    This atom has no unshared electron pairs, which makes it linear

    Rate this question:

  • 9. 
    Which of the following have a 109.5* angle between atoms?A.         B.         C. D.               E.           F. - ProProfs

    • A

    • B

    • C

    • D

    • E

    • F

    Correct Answer
    A. D
    Explanation
    the outer atoms are at the four corners of a tetrahedron, and the bond angles are all 109.5*

    Rate this question:

    Which of the following is true about C.? Check all the boxes that apply. A.         B.          C.  D.               E.           F. - ProProfs

    Which of the following is true about C.? Check all the boxes that apply. A.         B.          C.  D.               E.           F.

    • Its angle is 180*

    • CO2, H2O, and Na2S are examples of this

    • It involves 3 atoms

    • Its called linear triatomic

    • This shape says the molecule is polar

    Correct Answer(s)
    A. Its angle is 180*
    A. It involves 3 atoms
    A. Its called linear triatomic
    Explanation
    H2O is a bent triatomic shape, and this shape is NOT polar because the two opposing atoms are canceling one another's polarity out.
