Why do nitrogen molecules have triple bonds, whereas oxygen molecules have double bonds? How many valence electrons does each at

om have, and how does that affect the type of bond formed in each molecule? Draw Lewis dot diagrams to support your answer.

Explanation:

Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell. Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.

Plz mark me as the Brainleist.. (not forcing u.. if u like the answer) amd don't forget to tell me what is "Lewis dot diagrams "??

Brian Berg of lowa built a house of cards 4.88 m tall. Suppose Berg throws a ball from ground level
Step2247 [10]

Answer:

Vf = final velocity = 1.96 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

v_{f}^{2}=v_{o}^{2}-2*g*x

where:

Vf = final velocity [m/s]

Vo = initial velocity = 9.98 [m/s]

g = gravity acceleration = 9.81 [m/s²]

x = vertical distance [m]

v_{f}^{2}=(9.98)^{2}-2*9.81*4.88\\v_{f}^{2} = 99.6-95.74\\v_{f}=\sqrt{3.8544}\\v_{f}=1.96[m/s]

Note: The negative sign of the gravity acceleration means that the gravity acceleration is pointing in the opposite direction of the movement.

The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.

<h3>What is a magnetic field?</h3>

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

I is the current = 6.50 A

B is the magnetic field=f 2.71 X 10⁻⁵ T

The force on the wire is;

\rm F= BIL \\\\\ F=2.71 \times 10^{-5} \ T \times 6.50 \  A \times 1.50 \ m \\\\\ F=0.000264225 \ N

Hence, the force on one of the wires will be 0.000264 N.

To learn more about the magnetic field refer to the link;

11. Reflecting telescopes are popular because they're _______ than a refracting telescope.
Anon25 [30]
I do not know what the school expects as an answer, but advantage of reflecting telescopes is that there is only one major reflecting surface, so it is quite easy to create a 6 or 8 inch telescope by an amateur, after adding on a prism and an eyepiece.  (a microscope eyepiece could be used).
MY answer would be "easier to build".  (it still takes tens of hours to grind and polish the single plane surface to a parabolic surface).

Electromagnetic waves all have the same velocity in the same medium.  However, since frequencies vary widely, so do wavelengths.
