39. Which bond is least polar?<br> A) As-C1<br> B) Bi-CI<br> C) P-CI<br> D) N-C1
garik1379 [7]

Answer:

D) N-Cl.

Explanation:

The electronegativity of the elements in Group 5 (N. P As and Bi) decreases as we go down the Group so N is the most electronegative and chlorine is less able to draw electrons away from N than from the other elements in Group 5.

Why do a car's tires need more air in the winter than they do in the summer?
Hunter-Best [27]

Answer: Option (d) is the correct answer.

Explanation:

In winter's, temperature of atmosphere is low and due to this molecules of air present in the tire come closer to each other as they gain potential energy and loses kinetic energy.

Hence, air pressure decreases and there is need to fill more air in the tire.

Whereas is summer's, temperature is high so, molecules of air inside the tire gain kinetic energy and move rapidly from one place to another due to number of collisions. So, air pressure increases and there is no need to fill more air inside the tire.

Thus, we can conclude that the temperature is lower, so the air inside the tires contracts.

Oxygen decays to form nitrogen.
tatyana61 [14]

Answer:

Radioactive isotopes ranging from 11O to 26O have also been characterized, all short-lived. The longest-lived radioisotope is 15O with a half-life of 122.24 seconds, while the shortest-lived isotope is 12O with a half-life of 580(30)×10−24 seconds (the half-life of the unbound 11O is still unknown).

How to calculate the frequency of an ion
sergij07 [2.7K]

solution:

You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters. (1 nm = 1.0 x 10^{-9} m)

v=c\lambda \\v= (3.00 \times 10^8 m/s)/(6.9\times 10^-7 m) \\v = 4.35 \times 10^{14} s^{-1}
