In this model, electrons are found on unique levels and when jumping from one level to another, electrons emit light at a specific wavelength.

<h3>What is the Bohr model?</h3>

The Bohr model is an atomic model describing the properties of atoms and their constituents (electrons).

This model states different atoms have specific levels of energy where electrons can be located.

In conclusion, in this model, electrons are found on unique levels and when jumping from one level to another, electrons emit light at a specific wavelength.

3. The ideal gas law allows you to calculate which quantity that is not possible in Boyle's or Charles' law? a. volume b. pressu
erastova [34]

Answer:

d. The number of moles

Explanation;

  • According to the ideal gas;

P = nRT

where, P is the pressure, n is the number of moles, R is the ideal gas constant and T is the absolute temperature.

  • Charles's law and Boyle's law revolve around, volume, temperature and pressure.
  • According to Charles's law volume and temperature of a fixed mass of a gas are directly proportional at constant pressure.
  • That is; V α T
  • While based on Boyle's law, volume and pressure of a fixed mass of a gas are inversely proportional at constant temperature.
  • That is, Pα 1/V
  • We can, thus see that ideal gas law allows you to calculate number of moles unlike the case with Charles's and Boyle's law.

The rotten smell of a decaying animal carcass is partially due to a nitrogen-containing compound called putrescine. Elemental an
gtnhenbr [62]

Answer:C2H6N

Explanation:

Putrescine formula is C4H12N2

Assuming 100g sample is present

The percent changes to grams and it is converted to moles by dividing it with the atomic masses.

C= 54.50g/12 = 4.541moles

H = 13.73g/1 = 13.73moles

N= 31.77g/14 = 2.269moles

Divide through with the smallest moles value.

C= 4.541/2.269 = 2

H= 13.73/2.269=6

N= 2.269/2.269=1

Therefore the empirical formula is

C2H6N
