Answer:

The answer to your questions are given below

Explanation:

The answer to the questions given above can simply be obtained by writing the electronic configuration of each atom.

The electronic configuration of each atoms can be written as follow:

Fluorine, F (9) => 1s² 2s²2p⁵

Sodium, Na (11) => [Ne] 3s¹

Helium, He (2) => 1s²

Calcium, Ca (20) => [Ar] s²

Nitrogen, N (7) => 1s² 2s²2p³

Sulphur, S (16) => [Ne] 3s²3p⁴

Which compound (s) has(have) a molecular ion at 117 and a peak at 1720 cm-1 in its IR spectrum?
LenaWriter [7]

Answer:

Ethyl Acetate with a chemical configuration of : CH3CO2CH2CH3

Explanation:

Ethyl Acetate has a density of 902 kg/m³, molar mass of 88.11 g/mol and posses a boiling point of 77.1 °C.

It is to be understood that ethyl acetate is the  ester of ethanol and it is mostly produced in mass production and most especially used in the production of domestic materials especially materials like glue, efostics and dissolving agent. This is a highly toxic and flammable substance. However colorless and possess a sweet smell, it can be highly poisonous when ingested.

The final charge on each of the three separated spheres in part (b) is +3.0 μC. How many electrons would have to be added to one
marishachu [46]

Answer:

1.873\times 10^{13} electrons should be added to one of these spheres to make it electrically neutral.

Explanation:

Total charge on each sphere =  +3.0 μC =3\times 10^{-6} C

1 \mu C=10^{-6} C

In order to neutralize the positive charge equal magnitude of negative charge is to be added.

Total charge electrons, Q=  -3.0 μC =-3\times 10^{-6} C

Number of electrons = n

Charge on a single electron, e = -1.602\times 10^{-19} C

Q = n × e

-3\times 10^{-6} C=n\times (-1.602\times 10^{-19} C)

n=\frac{-3\times 10^{-6} C}{-1.602\times 10^{-19} C}=1.873\times 10^{13}

1.873\times 10^{13} electrons should be added to one of these spheres to make it electrically neutral.
