Hi :)

The bottom number tells you how many protons you have in the nucleus of this element.

In Krypton-84, this means that you have 84 nucleons, where 36 of these are protons, and the remaining 48 are neutrons.


Hope this helps :)

Arrange the eluting power of the listed solvents in normal-phase chromatography. The highest eluting power solvent is number 1;
BabaBlast [244]

Answer:

Explanation:

Part a

Normal Phase Chromatography

In the normal phase chromatography, the eluting power is highest for the solvent which has the highest polarity.

So from the given solvents as Methanol, Dichloromethane and Ethyl Acetate

the relative polarities are given as

Methanol=0.762

Dichloromethane (methylene chloride)=0.309

Ethyl Acetate=0.228

So the numbers are given as

Methanol :1

Dichloromethane (methylene chloride):2

Ethyl Acetate:3

Reverse Phase Chromatography

In the reverse phase chromatography, the eluting power is highest for the solvent which has the lowest polarity.

So from the given solvents as diethyl ether , water and toluene

the relative polarities are given as

Diethyl ether=0.117

Water=1.0

Toluene=0.099

So the alphabets are given as

Toluene :A

Diethyl ether: B

Water:C

Naturally occurring magnesium exists as three isotopes. 78.70% is Mg-24 with a mass of 23.98504 amu, 10.13% is Mg-25 with a mass
Nezavi [6.7K]

Answer:

The correct answer is 24.31 amu.

Explanation:

The formula for finding the average atomic mass = The sum of the percentage abundance of isotopes × the actual mass of isotopes

The average atomic mass = % abundance of Mg-24 × actual mass + % abundance of Mg-25 × its actual mass + % abundance of Mg-26 × its actual mass

Avg. Atomic mass = 0.7870 × 23.98504 + 0.1013 × 24.98584 + 0.1117 × 25.98259

Avg. atomic mass = 18.88 + 2.53 + 2.90 = 24.31 amu

The atomic mass of magnesium is 24.31 amu.
