What are the n, l, and possible ml values for the 2p and 5f sublevels?
elixir [45]

Answer:

1. 2p sublevels, n = 2, orbital <em>p</em>, l = 1, ml = 0, ±1

2. 5f sublevels n = 5, orbital <em>f</em>, l = 3, ml = 0, ±1, ±2, ±3

Explanation:

The rules for electron quantum numbers are:

1. Shell number, 1 ≤ n

2. Subshell number, 0 ≤ l ≤ n − 1

3. Orbital energy shift, -l ≤ ml ≤ l

4. Spin, either -1/2 or +1/2

So,

1. 2p sublevels,

n = 2, orbital <em>p</em>, so l = 1, ml = 0, ±1

2. 5f sublevels

n = 5, orbital <em>f</em>, so l = 3, ml = 0, ±1, ±2, ±3

Determine the expression for the equilibrium constant, KcKcK_c, for the reaction by identifying which terms will be in the numer
Yakvenalex [24]

Answer: Hello your question lacks some details below is the complete question

answer :

Numerator = CH₃OH

Denominator = (CO ) ( H₂)²

Explanation:

CO + 2H₂ ⇄ CH₃OH  ( formation of methanol )

hence for the equilibrium constant Kc

Numerator = CH₃OH

Denominator = (CO ) ( H₂)²

<u><em>Placing into the Bin </em></u>

Numerator : CH₃OH

Denominator : (CO ) ( H₂)²

Not Used : ( CO )² ,  H₂ ,  ( CH₃OH ) ²

Which equation correctly represents the first electron affinity (ea1) of calcium?
AleksandrR [38]

Answer :

The correct answer is : Ca (g) + e^- \rightarrow Ca^- (g)

Electron Affinity :

It is defined as energy released  or absorbed when an electrons is added to neutral isolated atom in gaseous state .

The first electron affinity is the energy absorbed or released when one electron is to  outermost  shell of a neutral atom .

The first electron affinity  is generally negative , when electron is added to non metals .  While when electron  is added to metals , the electron affinity is positive.

More the negative electron affinity , more the atom has tendency to accept the electron .

For example :  F(g) + e⁻  → F⁻(g)   ΔH⁰ = - 328.0\frac{KJ}{mol}

- 328.0\frac{KJ}{mol}  represents  first electron affinity of Fluorine atom .

First electron affinity for Calcium can be written as :

The symbol for Calcium in its ground state is Ca . Since the electron (e⁻) is added so it is written on left  side or reaction . The calcium will accept the electron and will form a negative ion as Ca⁻ .

Hence the equation goes as

Ca (g) + e^-\rightarrow Ca^- (g)
