Do you expect a strong chemical bond to have a higher or lower frequency than a weak bond?

Chemistry
1 answer:
Llana [10]3 years ago
6 0

Answer:

Higher frequency  

Explanation:

We can imagine a chemical bond between two atoms as if it were two balls connected by a spring.

According to Hooke's Law, the stretching frequency f is

f = \dfrac{1}{2 \pi}\sqrt{ \dfrac {k}{\mu}}

where µ is the reduced mass of the system

\mu = \dfrac{m_{1} + m_{2}}{m_{1}m_{2} }

The strength of the bond is analogous to k, the force constant of the spring. Then,

f \propto \sqrt{k}

Thus, the stronger the bond, the greater the frequency of vibration.

Answer:

Follows are the explanation to this question:

Explanation:

When the drug is negatively charged, its negative electrolyte is annihilated to just the positive electrode. It is enticed, and it may not have a picture showing the electrode, however, We suppose that electrodes from either side of a skin slice. Its negative electrode will bypass or push thru the skin if in front of the counter terminal this becomes a red-positive electrode.

What is the main cause of any change of state?
svetoff [14.1K]

Answer:

Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid).
