1 answer:
Ratling [72]4 years ago
4 0

Explanation:

no of moles = no of atoms ÷ avogadro's number

= (9.8×10^24) ÷ (6.02×10^23)

16. Which is an example of a transverse wave? (1 point)
GarryVolchara [31]

Answer:

<h2>Transverse wave,</h2>

Explanation:

<h3>motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.</h3>

Phosgene is a highly toxic gas made up of carbon, oxygen, and chlorine atoms. Its density at 1.05 atm and 258C is 4.24 g/L. (a)
VikaD [51]

Answer:

Molar mass = 99 g/mol

Explanation:

Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2

The molar mass is given as the sum off the individual atomic mass of the elements in the compound.

Molar mass = C + O + 2Cl

Molar mass = 12 + 16 + 2(35.5)

Molar mass = 99 g/mol

What is a common reason for observing an increased chemical shift of a c-h proton
stira [4]

Deshielding due to an electronegative element close by is the common reason for observing increased chemical shift of a c-h proton

<h3>What is a chemical shift? </h3>

The resonance frequency of a proton in relation to a standard compound is represented by chemical shift. Chemical shift, which is measured in ppm and is represented by the sign (δ),  (parts per million).The chemical shift in a proton NMR spectrum provides details about the targeted proton's chemical surroundings. The structure of the investigated substance, especially electronegative components or effects, has a significant impact on the chemical shift value. Electronegative elements' ability to remove electron density from the proton, which raises the chemical shift value, is one explanation for this. The proton is more exposed to the magnetic field that is being applied externally as a result of this process, which is referred to as de-shielding.
