which statement best describes the polarity of the molecule h, s?
a. it is polar, because the bond polarities add together in a linear
molecule.
b. it is nonpolar, because the bond polarities cancel each other out in
a linear molecule.
o
c. it is polar, because the bond polarities add together in a bent
molecule.
o
d. it is nonpolar, because the bonds between hydrogen (h) and sulfur
(s) are not polar.

             The correct Option is C (It is polar, because the bond polarities add together in a bent  molecule.)

Explanation:

The molecular structure of Hydrogen Sulfide (H₂S) is attached below;

The molecule of Hydrogen Sulfide is polar due to following two reasons;

1)  Electronegativity Difference:

                                                   Sulfur has an electronegativity of 2.58 while that of Hydrogen is 2.20. Hence, sulfur being more electronegative attracts the electron fro hydrogen making it slightly partial positive and increasing electron density and becoming slightly partially positive. So, we can call this bond as slightly polar bond.

2) Dipole Moment:

                             Dipole moment occurs when the bond is polar. Being a vector quantity it strongly depends upon the geometry of a molecule. In H₂S the two polar bonds cannot cancel each other because they are not in opposite direction  as that found in case of CO₂. Hence, H₂S is a polar compound.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
