Answer:

A) decreasing frequency.

Explanation:

The frequency is the number of occurrences of a repeating event per unit of time.

In the figure attached two examples of waves are shown.

From the table in the question, we know that the wavelength increase as time increase, so the time in which the curve pass through some value becomes more and more separated from the previous, and that is equivalent to decrease in the frequency. In other words, the shorter the wavelength, the higher the frequency (there are more repetitions of the event per unit of time); in this exercise the wavelength is increased, then the frequency decrease.

serg [7]

Answer:

One carbon atom and the nitrogen atom have nonzero formal charges.

Explanation:

The compound Acetonitrile has sixteen valence electrons as is easily San from its structure. It contains a carbon nitrogen triple bond with a lone pair of electrons on nitrogen. All atoms satisfy the octet rule and there is no hyper valent atom in the molecule.

The formal charge an carbon and nitrogen is calculated as follows;

No. of valence electron on atom - [non bonded electrons + no. of bonds]

Therefore, for carbon and nitrogen, we have;

formal charge on carbon = 4 - (0 + 4) = 0

formal charge on nitrogen = 5 - (2 + 3) = 0

Hence carbon and nitrogen both possess zero formal charges.
