You run a chromatography of inks belonging to three crime suspects and from a ransom note. the inks resolve into the following numbers of spots: suspect a=2, suspect b=4, suspect c=3, note=5. which suspect would you most likely bring in for questioning

No subject.

Explanation:

Hello,

At first, let's remember that chromatography is the available technique for separating mixtures into its components based on the principle of stationary and mobile phases. Such technique is also used to separate inks, thus, the stationary phase is paper and the mobile phase is solvent/sample. The ink on the pen is a mixture of several dyes which can be separated and subsequently shown in several spots.

In this question, it is stated that the ink from the notes shows 5 spots while the ink from the suspect's pen is only 2 spots (suspect A), 4 spots (suspect B) and 3 spots (suspect C).

Thus, by considering the aforementioned fact, one concludes that there is no match, but that approaches the number 5 spots of the ink note is suspect B with 4 spots.

Best regards.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
