How many atoms in the pictured molecule can form hydrogen bonds with water molecules?

Chemistry
1 answer:
ddd [48]3 years ago
4 0

Answer:

  • <em><u>3</u></em>

Explanation:

Please, find the  image with the pictured molecule for this question attached.

The molecule has one oxygen atom (red) covalently bonded to one hydrogen atom (light grey), one nitrogen atom (blue) covalently bonded to two hydrogen atoms (light grey), and two carbon atoms (dark grey) bonded each to two hydrogen atoms (light grey).

<em>Hydrogen bondings</em> are intermolecular bonds (bonds between atoms of two different molecules not between atoms of the same molecule). The hydrogen bonds are attractions between the positive end of one hydrogen atom and the negative end of a small atom of other molecule (N, O, or F).

Since, nitrogen and oxygen are much more electronegative than hydrogen atoms, you conclude that:

  • The two hydrogen atoms covalently bonded to the nitrogen atoms have considerably partial positive charge.

  • The hydrogen atom covalently bonded to the oxygen atom also has a a relative large partial positive charge.

So, those are three ends of the molecule that can form hydrogen bonds with water molecules.

The hydrogen bondings are only possible when hydrogen is covalently bonded to N, O or F atoms.

A spectrophotometer measures the transmittance or the absorbance, or both, of a particular wavelength of light after it has pass
Cerrena [4.2K]

Answer:Answer: The step that is NOT necessary to complete before a cuvette is placed into the spectrophotometer is option B (Write, in ink, either sample or blank on the side of the cuvette to keep track of them)

Explanation: spectrophotometer is an instrument used to measure the light intensity absorbed after being passed through a solution. Before the absorbance of the sample solution, a solvent solution called blank is used for the calibration of the machine and this blank solvent is placed in a cuvette. The procedure usually comes first before the main sample is processed. Therefore there is no need to

Write, in ink, either sample or blank on the side of the cuvette to keep track of them. This is so since sample and blank is not absorbed at the same time by the machine.
