Solution of the Schrödinger wave equation for the hydrogen atom results in a set of functions (orbitals) that describe the behav

kvv77 [185]

Answer :

'n' specifies → (B) The energy and average distance from the nucleus.

'l' specifies → (C) The subshell orbital shape.

'ml' specifies → (A) The orbital orientation.

Explanation :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as $m_l$ . The value of this quantum number ranges from $(-l\text{ to }+l)$ . When l = 2, the value of

Spin Quantum number : It describes the direction of electron spin. This is represented as $m_s$ . The value of this is $+\frac{1}{2}$ for upward spin and $-\frac{1}{2}$ for downward spin.

As per question we conclude that,

'n' specifies → The energy and average distance from the nucleus.

'l' specifies → The subshell orbital shape.

'ml' specifies → The orbital orientation.

The question is asking to state the conclusion that can be formulated, base on the problem or the given analysis of the data, about the accuracy and precision and base on my research, i would say that the Accuracy is Poor but the Precision is Good. I hope this would help you

A _____________reaction mechanism involves loss of a leaving group, formation of a ________ followed by the removal of a proton

Molodets [167]

Answer:

The correct answer is Option C (E1) and Option B (carbocation).

Explanation:

Intramolecular immunity idols are considered as that of the formation mechanism with E1 responses or reactivity.
Reactants with E1 were indeed obligations of both parties, meaning that an E1 reaction was conducted thru all the two stages known as ionization but rather deprotonation. Involves the absence of either an aromatic ring, a carbocation has been generated throughout the ionization solution.

Some other possibilities offered aren't relevant to the procedure outlined. So the above alternative is accurate.

What happens when the kinetic energy of particles in a liquid state increases?

Hitman42 [59]

Answer:

When the kinetic energy of particles in liquid increases, the particles are pushed farther apart. This can result in the expansion of matter. More pressure will be exerted on the container in which this liquid is stored.
