To determine

The shape of the molecule N2O and its polar or nonpolar nature.

Answer to Problem 32E

The shape of the molecule N2O is linear as shown:

An Introduction to Physical Science, Chapter 12, Problem 32E , additional homework tip 1

The molecule N2O is polar.

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 N2O is linear as shown:

An Introduction to Physical Science, Chapter 12, Problem 32E , additional homework tip 2

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 N2O is polar.

Conclusion:

Therefore, the shape of the molecule N2O is linear as shown:

I’m working on a loop-the-loop physics question involving rolling motion and would like help understanding the steps. A billiard ball with radius r and mass m rolls without slipping down a track and into a vertical loop of radius R. It has just enough speed to barely make it over the top of the loop. a) In class/problems before, we found that for an object that slides without friction into the loop (no rotation), the minimum starting height needed to just clear the top is H=52R.H = \frac{5}{2}R.H=25R. Now the object is a rolling billiard ball instead. If this ball rolls without slipping and just manages to clear the top, does it need to start from a different height than the sliding object? If so, should that height be larger or smaller? Please explain conceptually, using energy ideas, without doing detailed calculations yet. b) When the ball is just barely making it over the top of the loop, what are:(i) the normal force acting on the ball at the top of the loop, and(ii) the ball’s...

A grinding wheel is already spinning clockwise at 190 RPM, and then a motor increases its speed with a constant angular acceleration of 5.00 rad/s2 until the wheel reaches 475 RPM. • Since the wheel is turning clockwise and its speed is increasing, what would be the direction of the angular acceleration (clockwise or counterclockwise)? And with whatever sign convention you choose, what sign would you give that acceleration? • As the wheel speeds up from 190 RPM to 475 RPM, how can I figure out the total number of revolutions it completes? I’d appreciate seeing the setup and the angular-kinematics steps involved. • I’m also trying to find out how long the speed-up takes under that constant angular acceleration. Could you show how to compute the time based on the information above? • Once the wheel reaches the 475-RPM speed, its diameter is 0.28 m. Using that, what would be the tangential (linear) speed at the outer edge?

What would the object distance need to be in order to obtain a magnification of -1?4. For a converging lens of focal length f, where would you place the object to obtain an imageas far from the lens as possible? 5. Purpose: State the purpose of the experiment. Explain exactly what the experimentinvestigates and what you are trying to determine. Be as explicit and thorough as possible.Explain the theory behind the experiment. Explain exactly what you measured and how itwas used to fulfill the purpose of the lab.6.

Suggest possible improvements in the experiment which could reducethese uncertainties.
