Explain why protons attached to nitrogen (i.e. n-h show broad peaks in the 1h nmr and do not couple to other protons.

1 answer:

7 0

The element Nitrogen is usually present in almost all proteins, and it also forms strong bonds due to its ability to form a triple bond with its self, also to other elements.

<span>The nitrides use a variety of different oxidation and almost all the oxides forms gasses are at 25 degrees Celsius. The oxide of nitrogen are acidic, thus, easily attaching protons.</span>

On a good night, the front row of the Twisted Sister concert would surely result in a 120 dB sound level. An IPod produces 100 d

Answer:

100 iPods

Explanation:

The deciBell scale is logarithmic, and thus, it turns multiplying into adding.

Initially, it was the Bell scale, purely logarithmic, where "times 10" is translated into "plus 1" (just like normal logs). However, the steps became too big and so they divided the Bell in 10 parts, the deciBell.

The levels above could well have been called 10B and 12B.

Usually, we define the dB scale for intensity as:

I(dB) = 10•log(I)

Thus,

I = 10^(I(dB)/10)

Now 120 dB gives us units of I = 10^(120/10) = 10^12 Pa (assume the dB are measured to 1 Pa) and 100 dB is 10^10 Pa.

Thus, we would need 100 ipods to get the same intensity

Explanation:

A telescope is a device that allows us to see objects that were very far from us, it is built by the combination of two lenses, the one with the lowest focal length near the eye and that is the one or the one with the greatest focal length, the most eye-flounder . The magnification of the telescope is

m = - f₀ / $f_{e}$
