Answer:
D
Explanation:
because the higher the wavelength the shorter the pitch and the shorter the wavelength the higher the pitch
Answer: 0.335 mols Ca(NO3)2
Explanation: To go from grams to mols you divide grams by the molar mass of the substance so, 55/164.088 = 0.335
TMS has 12 protons which are all equivalent and four carbons, which are also all equivalent. This means that it gives a single, strong signal in the spectrum, which turns out to be outside the range of most other signals, especially from organic compounds.
Different isotopes of the same element emit light at slightly different wavelengths, the minimum number of slits is mathematically given as
N=1820slits
<h3>What minimum number of slits is required to resolve these two wavelengths in second-order?</h3>
Generally, the equation for the wave is mathematically given as

Where the chromatic resolving power (R) is defined by

R = nN,
Therefore


and


In conclusion, the minimum number of slits is required to resolve these two wavelengths in second-order

Therefore

N=1820slits
