B. That the reaction is reversible

The ↔ sign is used in reactions where the equilibrium constant of the forward reaction is close to the equilibrium constant of the backward reaction. This results in the backward reaction being possible. An example of such a reaction is:
N₂ + 3H₂ ↔ 2NH₃

sveta [45]

Answer:

C. The energy released as the bonds in the reactants are broken is greater than the energy absorbed as the bonds in the product are formed.

Explanation:

  • CO + 2H₂ ⇌ CH₃OH     ΔH <0

As ΔH is negative, the given reaction is exothermic.

That means that <em>the enthalpy of the product is less than the enthalpy of the reactants</em>. In other words, part of the energy from the reactants is used to form new bonds (between C and H, for example), while the other part is transfered outside the system as heat.

Thus the correct answer is C.

If L = 5, then the magnetic quantum number "mL" can be equal to
Anit [1.1K]

b. -5, -4, -3, -2, -1, 0, +1, +2, +3, +4, +5

<h3>Further explanation</h3>

Each orbital in an atom consists of 4 quantum numbers  

n is the principal quantum number.  

l is the angular momentum / azimuthal quantum number  

ml, the magnetic quantum number  

ms, the electron-spin quantum number  

Value of n: positive integer  

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

ml value: between -l to + l  

ms value: +1/2 or -1/2  

So for L=5, mL value : -5 to +5
