Answer:
(c) The retention time would be higher (d) The retention time would be lower.
Explanation:
For the polar solutes which were separated using the hydrophilic interaction chromatography (HILIC) with a strongly polar bonded phase, the retention time would be higher if eluent were changed from 80 vol% to 90 vol% acetonitrile in water.
However, for the polar solutes which were separated using the normal-phase chromatography on bare silica with methyl t=butyl ether and 2-propanol solvent, the retention time would be lower if the eluent were changed from 40 vol% to 60 vol% 2-propanol.
There are 22 bonding parts
Understanding chemistry and its principles enables us to predict and understand various properties of substances. For example, because we know that ionic bonds are very strong and difficult to break, we know that any substance that has these bonds will have a high melting point, because melting is a process that requires the intermolecular bonds present in the solid state to be broken. This can be applied to table salt, sodium chloride, which has an ionic structure and a melting point of almost 800 degrees Celsius. Similarly, many other properties and characteristics may be predicted using concepts of chemistry.
Answer:
= 7392 kg solution
Explanation:
detailed solving is given in the attached document.
Plants fertilized one per week with Super Plant Food Formula have been shown in testing to produce twice as much fruit as plants that are not.
That answer is the most scientific because it states the word "testing" and in science they do a bunch of test to make a scientific claim.
