I would say when an atom has its valence electron shell filled like a noble gas has, it is not easily changed.

I’m not entirely sure of what you’re asking, but if you’re talking about bonding then it would be an ionic bond that is not easily changed.

In column chromatography (microscale), after loading it with solvent and adsorbent and prior to loading the sample, what level s
Nikolay [14]

Answer:

Explanation:

You should allow the solvent to drop to the level of the adsorvent, so it would never run dry.

When you let your sample to run dry it will never finish to flow from the adsorbent depending of it polarity.

Water should not be used because it can dissolve the adsorbent.

You could use another technique to identify the compound, as an infrared or a ultraviolet detector. You can also, if you know the compounds, identify it for the retention time, for example, if you need to detect two compounds, one more polar than the other, and use a polar adsorbent and a non-polar solvent, the first compound to exit the column will be the less polar one, because it will have a bigger interaction with the solvent than the stationary phase (adsorbent) and will go faster, the second will be the more polar one, because it will have a bigger interaction with the stationary phase.

garri49 [273]

Answer:

120000drops

Explanation:

Average blood in human blood = 6L - 6*1000 = 6000ml

1 ml of blood is equal to 20 drops

6000ml of blood makes 20*6000 = 120000 drops
