Answer:

DNA fingerprints

Explanation:

Tandem mass spectrometry is used to obtain DNA fingerprints as it is used for sequencing of both DNA and RNA.

It involves multiple fragmentation.

In this mass spectrometry, the substrate is first converted to ions and then the ions are separated based on mass to charge ratio. Now these ions separated are further processed for fragmentation producing daughter or product ions. These are again separated and analyzed based on mass to charge ratio.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit ___?

Tju [1.3M]

Ans: As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit will increase.

The energy (E) is related to the frequency (ν) by the following equation:

E = hν

where h = planck's constant

The change in energy i between levels is:

ΔΕ = h(Δν) -----(1)

Based on the above equation, as the changes in energy levels increase, the frequency of emitted radiation will also increase.

If a solution contains 3 moles/liter of sodium chloride (nacl, made of sodium ions and chloride ions), what is the osmolarity of

valkas [14]

Answer: Osmolarity of the sodium chloride solution is 18 Osmol/L.

Explanation:

Osmolarity is defined as the the concentration of the solution which is expressed as the total number of solution particles present in one liter of solvent.

We are given the molarity of the solution which is 3mol/L and to convert it into osmolarity, we will multiply the number of osmoles that are produced by the solute.

Osmole is defined as the particles that contribute to the osmotic pressure of a solution.

The solute given here is sodium chloride (NaCl). Number of osmoles can be determined by the dissociation of this solvent into ions.

The equation given by the dissociation of NaCl:

$NaCl\rightarrow Na^++Cl^-$

1 mole of sodium chloride produces 2 moles of ions.

So, 3 moles of sodium chloride will produce = (3 × 2) = 6 moles of ions.

Hence, osmolarity of the sodium chloride solution will be $6\times 3mol/L=18Osmol/L$
