<u>Answer:</u> The number of sub-levels the for the energy level n = 4 are 4.

<u>Explanation:</u>

The number of sub-levels in an energy level is determined from the azimuthal quantum number.

<u>Principle Quantum Number:</u> This quantum number describes the size of the orbital. It is represented by n where n = 1,2,3,4....

<u>Azimuthal Quantum Number:</u> This quantum number describes the shape of the orbital and also determines the sub-levels in an energy level. It is represented by the symbol 'l'. The value of 'l' ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

For n = 4, the value of l = 0(s), 1(p), 2(d), 3(f) and these are the number of sub-levels.

Hence, the number of sublevels the for the energy level n = 4 are 4.

1,4-Pentadiene has a AHhydro = -254 kJ/mol while trans-1,3-pentadiene has a AHhydra = -226 kJ/mol. Explain this difference in he
julsineya [31]

Answer:

trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.

Explanation:

Here, \Delta H_{hydro}=H(hydrogenated pdt.)-H(diene)

H(hydrogenated pdt.) is same for both 1,4-pentadiene and 1,3-pentadiene as they both produce pentane after hydrogenation

H(diene) depends on stability of diene.

More stable a diene, lesser will be it's H(diene) value (more neagtive).

trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.

Hence, \Delta H_{hydro} is higher (less negative) for trans-1,3-pentadiene

What chemical property must argon have to make it a suitable choice for light bulbs?
wlad13 [49]
Argon is a suitable choice for light bulbs because it's inert. Compared to a reactive gas like oxygen, the metal filimant would burn up in a reactive  enviroment, which is why a noble gas is used.
