The base peak in the mass spectrum of 3-methylpentane has the most plausible value at m/z=57. Hydrocarbons often undergo mass spectroscopic fragmentation at a branch.
<h3>What does the mass spectrometry Mz value mean?</h3>
The horizontal axis in a mass spectrum is stated in units of mass divided by charge number, or m/z. With GCMS, z is usually always 1, hence the mass is frequently determined by the m/z value.
<h3>What is the M Z of the base peak?</h3>
The base peak of the spectrum is defined as the peak with the arbitrary intensity value of 100. The molecular ion, which has a peak at m/z=72, is what determines the molecule's molecular mass.

Answer:
D. 4.281 x 10⁻¹⁹ Joules.
Explanation:
- To get the change in energy, we can use the relation:
<em>E = (hc)/λ</em>
where,
E is the energy of the atom.
h is Planck’s constant = 6.626 x 10⁻³⁴ J.s.
c is the speed of light = 2.998 x 10⁸ m/s.
λ is the wavelength of photon = 4.64 x 10⁻⁷ m.
<em>∴ E = (hc)/λ</em> = (6.626 x 10⁻³⁴ J.s)(2.998 x 10⁸ m/s)/(4.64 x 10⁻⁷ m) = <em>4.281 x 10⁻¹⁹ J.</em>
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For C and N,
E.N of Nitrogen = 3.04
E.N of Carbon = 2.55
________
E.N Difference 0.49 (Weakly Polar Covalent)
For N and S,
E.N of Nitrogen = 3.04
E.N of Sulfur = 2.58
________
E.N Difference 0.46 (Weakly Polar Covalent)
For K and F,
E.N of Fluorine = 3.98
E.N of Potassium = 0.28
________
E.N Difference 3.70 (Ionic)
For N and N,
E.N of Nitrogen = 3.04
E.N of Nitrogen = 3.04
________
E.N Difference 0 (Non Polar Covalent)
Answer:A=1 B= 3 C=2
Explanation: if you put a 2 where C is then the amount will then change to P4O6. so therefore keeping the P4 on the left side the same will keep that same amount & putting a 3 with the O2 on the left will increase the amount for it to be equal on both sides.
hope that makes sense sorry!
