Hi there,
In a molecule<span>, </span>atoms<span> are bonded together by single, double, or triple bonds. An </span>atom<span> has a nucleus surrounded by electrons. ... So another </span>difference between atoms and molecules<span> is that when similar </span>atoms<span> combine together in varying numbers,</span>molecules<span> of different properties can be formed.
hope you understand</span>
Answer:
9
Explanation:
The structure of fluorophore used in the experiments has been drawn in the attachment. And from the drawing counting we can say that there are 9 sp2-hybridized carbon atoms present. Fiuorophores are a fluorescent chemical compound that can re-emit light upon light excitation. Normally used to produce absorbance and emission spectra.
Answer:
Alpha feto protein AFP
Explanation:
Plasma protein bio marker alpha feto protein is detected by the liver test to determine the presence of liver cancer in a patient.
High levels of alpha feto proteins is also a sign of cancer of ovaries and testicles and also liver non cancerous diseases that is cirrhosis and hepatitis.
The increased levels of two liver enzyme AST and ALT is also indicator of hepatic cancer.
Answer:
CH3COOH
Explanation:
CH3COOH has the highest boiling point because it participates in the strongest intermolecular interactions. The -OH group can participate in hydrogen bonding with other -OH groups. Hydrogen bonds are very strong because they are the result of large partial positive charge on the hydrogen and large partial negative charge on the oxygen. When surrounded by other -OH groups, the partial positive charge on the hydrogen can form temporary bonds with the partial negative charge of an oxygen on another molecule. The stronger the intermolecular interactions, the more difficult they are to overcome, thus increasing the boiling point.
The strongest IMF the other molecules participate in are dipole-dipole. These interactions are not as strong as hydrogen bonding.
