Which of the following statement(s) is/are consistent with the Bohr theory of the atom (and no other)?

Chemistry

olganol [36]3 years ago

Answer:

(2) The lowest energy orbits are those closest to the nucleus.  

Explanation:

In the Bohr theory  the electrons describe circular orbits around the nucleus of the atom without radiating energy, therefore to maintain the circular orbit, the force that the electron experiences, that is, the coulombian force due to the presence of the nucleus, must be equal to the centripetal force.

The electron only emits or absorbs energy in the jumps from one allowed orbit to another, with only one jump occurring at a time, from layer K (n = 1) to layer L (n = 2),  without going through intermediate orbits. In said change it emits or absorbs a photon whose energy is the difference in energy between both levels.

In Bohr's model, it is stipulated that the energy of the electron is greater the greater the radius r, so the lowest energy orbits are those closest to the nucleus.

At what temperature will 0.100 molal (M) NaCl(aq) boil? <br> Kb= 0.51 C kg mol^-1
Talja [164]
The increase of the boling point of a solution is a colligative property.

The formula for the increase of the normal boiling point of water is:

ΔTb = Kb * m

Where m is the molallity of the solution and Kb is the molal boiling constant in °C/mol.

ΔTb = 0.51 °C / m * 0.100 m = 0.051 °C.

So, the new boiling temperature is Tb = 100°C + 0.051°C = 100.051 °C.

Answer: 100.051 °C

Alcohol or acid will travel the furthest up the paper chromatography? pls help thanks and explain
d1i1m1o1n [39]

Answer:

True

Explanation:

Yes.

The distance that the molecules move depends on their solubility in the solvent and the size of the molecules. Heavy molecules will travel slower and therefore travel a shorter distance in the time the chromatography is run.

We know from such things as felt tip pens that colourings can be soluble in different solvents. Water soluble felt pens have colours that are - well - water soluble. Permanent felt pens have colours that are insoluble in water but that are soluble in another solvent. This could well be alcohol.

The water soluble colours may also be soluble in alcohol. The solubility in alcohol will be different from the solubility in alcohol, and so the Rf value ( the distance travelled) will also be different.

Because of the complicated shapes of the colours, the colours may not have the same order in the Rf values in the different solvents.

Find ∆G for a cell whose potential is +0.24 V with 4 moles of electrons exchanged.
Setler [38]
We need to use the following formula
ΔG= -nF E_{cell}

E_{cell}= 0.24V
n= 4 moles
F= constant= 96500C/mol

let's plug in the values.

ΔG= -(4)(96500)(0.24)= -92640 J or -92.6 kJ
