Through mass spectrometry, we can define 4 different isotopes of the BrCl molecule:
⁸¹Br³⁷Cl, ⁸¹Br³⁵Cl, ⁷⁹Br³⁷Cl, ⁷⁹Br³⁵Cl
Masses of the different individual isotopes:
³⁷Cl=36.966
³⁵Cl=34.968
⁸¹Br=80.916
⁷⁹Br=78.918
Masses of 4 different isotopes of the BrCl molecule:
⁸¹Br³⁷Cl=80.916+36.966=117.882
⁸¹Br³⁵Cl=80.916+34.968=115.884
⁷⁹Br³⁷Cl=78.918+36.966=115.884
⁷⁹Br³⁵Cl=78.918+34.968=113.886
Answer:
Newtonian fluids have a constant viscosity that does not change and non newtonain fluids have a viscosity that varies.
Explanation
Newtonian fluids have a constant viscosity and a zero shear rate at zero shear stress. Non-Newtonian fluids have a variable viscosity and a varible relationship with shear stress.
Answer:
The experimental feature of the MALDI-MS technique which allows the separation of ions formed after the adduction of tissue molecules:
B) Velocity of ions depends on the ion mass-to-charge ratio.
Explanation:
- The option a is not correct as distance traveled by ions doesn't depend upon the ion charge rather it depends upon time for which you leave the sample to run.
- The option b is correct as velocity of ions depends on the ion mass-to-charge ratio because separation is done due to mass to charge ratio feature.
- The option c is incorrect as time of travel is not inversely proportional to the ion-to-mass ratio because the ion will move across the gel until you stop the electric field.
- The option d is not correct as electric field between MALDI plate and MS analyzer is though uniform but this feature doesn't allow the separation of ions.
