The answer would be C8H18, or octane. Column chromatography is a separation technique that works off of polarity. The stationary phase, in column chromatography, are non-modified silica gels. Silica gels are normally polar. This means the solvent that will elute first are non-polar molecules...then polar molecules. The polar silica gels have a stronger interaction with polar molecules like CH3OH, and therefore will lag the solvent. Additionally, as you decrease the carbons, in hydrocarbons, the molecule becomes more polar. This is not C6H6 isn't the answer and octane is.
I don't think it's any of the above. Because there is two double carbon bonds and it belongs to an alkene, it should be an ethene molecule.
<span>No, they are just moving very slowly or vibrating in a closed space so that it makes the item solid. Hope I helped. :)</span>
Answer:
These metals exist in only one ion; therefore, they cannot give away more than one ion. Thus, even though they are transition metals, aluminum, zinc and silver are only (I) and never require Roman numerals written after their names.
