Which of the quantum numbers relate(s) to the electron only? Which relate(s) to the orbital?
olganol [36]

Answer:

Schrodinger's proposal, considered as the 5th atomic model, is to describe the characteristics of all the electrons in an atom, and for this I use what we know as quantum numbers.

Quantum numbers are called with the letters n, m, l and s and indicate the position and energy of the electron. No electron of the same atom can have the same quantum numbers.

Explanation:

n = main quantum number, which indicates the level of energy where the electron is, assumes positive integer values, from 1 to 7 and it is related to the orbital too.

I = secondary quantum number, which indicates the orbital in which the electron is located, can be s, p, d and f (0, 1, 2 and 3).

m = magnetic quantum number, represents the orientation of the orbitals in space, or the type of orbital, within a specific orbital. Assumes values ​​of the negative secondary quantum number (-l) through zero, to the positive quantum number (+ l).

s = quantum number of spin, which describes the orientation of the electron spin. This number takes into account the rotation of the electron around its own axis as it moves around the nucleus. Assumes only two values ​​+1/2 and - 1/2

Dude pls help
Anestetic [448]

Answer:

KO is the limiting reactant.

0.11 mol O₂ will be produced.

Explanation:

4 KO₂  +  2 H₂O  ⇒  4 KOH  +  3 O₂

Find the limiting reagent by dividing the moles of the reactant by the coefficient in the equation.

(0.15 mol KO₂)/4 = 0.0375

(0.10 mol H₂O)/2 = 0.05

KO₂ is the limiting reagent.

The amount of product produced depends on the limiting reagent.  To find how much is produced, take moles of limiting reagent and multiply it by the ratio of reagent to product.  You can find the ratio by looking at the equation.  For every 4 moles of KO₂, 3 moles of O₂ are produced.

0.15 mol KO₂  (3 mol O₂)/(4 mol KO₂) = 0.1125 mol O₂

0.11 mol O are produced.

A certain liquid X has a normal boiling point of 111.20 celsius and a boiling point elevation constant Kb=0.95. calculate the bo
Goshia [24]

Answer: the boiling point is = 137.325°C

Explanation:

From the formula: ∆Tb= Kb*m

From the question, Kb= 0.95, m= 27.5, T1= 111.2°C

Substitute into ∆Tb= Kb*m

∆Tb= 0.95*27.5= 26.125

∆Tb= T2-T1

Hence

T2- 111.2=26.125

T2= 26.125+ 111.2= 137.325°C
