7.2/4.0=1.8 then, 4.0=7.2/1.8
Answer:it is 4
Explanation:
I multiple and divided it
5100.0 has 5 but a 5.100 x 10 cubed(3) has only 4
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.
Answer:
Two Electrons.
Explanation:
Strontium is the atom with atomic number 38, and electron configuration is [Kr] 5S^2 which mean just two electrons more than Krypton which one of the Noble gases.
