(a)
The shape of the molecule
N 2 O
and its polar or nonpolar nature.
(a)

Answer to Problem 32E
The molecule
Explanation of Solution
Given Info: Refer to Table 12.6 in the textbook to predict the shape of the molecule.
Explanation:
The shape of the molecule
The central atom has two surrounding regions.
The polarity of a molecule depends on the electronegativity of atoms in that molecule and the shape of the molecule. A molecule which has one polar bond is polar.
A molecule which has all nonpolar bonds is nonpolar.
The symmetric molecule will be nonpolar because the polarity of bonds is canceled out. Thus an asymmetric molecule is polar because the polarity of bonds is not canceled.
Therefore, the asymmetric molecule
Conclusion:
Therefore, the shape of the molecule
The molecule
(b)
The shape of the molecule
SO 4 2 −
and its polar or nonpolar nature.

If the statement is false, correct the statement to make it true. 12. An object in uniform circular motion has a constant velocity while experiencing centripetal acceleration. 13. An object travelling in uniform circular motion experiences an outward centrifugal force that tends to pull the object out of the circular path. 14. An object with less inertia can resist changes in motion more than an object with more inertia. 15. For an object sliding on a horizontal surface with a horizontal applied force, the frictional force will always increase as the applied force increases.arrow_forward
