<h3>What is spectrometric method?</h3>
  • A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
  • Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.
  • There are two main techniques used among the various forms of spectrophotometry:
  • ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
  • and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.
  • Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.

How many vibrational modes does ethanol have? Explain why.
Artyom0805 [142]

Answer:

The ethanol has 21 vibrational modes.

Explanation:

A molecule can show 3 types of motions: one external called translational and two internal called rotational and vibrational.

In order to calculate the vibrational modes of a molecule we need to know the degrees of freedom of this molecule, it means the number of variables that are involved in the movement of this particle.

If we know that atoms are three dimensional we will know that they have 3 coordinates expressed as 3N. But the atoms are bonded together so they can move not only in translational but also rotational and vibrational. So, the rotational move can be described in 3 axes and the other vibrational move can be described as

3N-5 for linear molecules

3N-6 For nonlinear molecules like ethanol

So using the formula for nonlinear molecules where N is the amount of atoms in the chemical formula, so ethanol has 9 atoms

3(9)-6= 21

Thus, ethanol has 21 vibrational modes.

Do protons have attraction for neutrons yes or no
eduard

Answer: Yes, they do.

Explanation: Neutrons and protons are made up of smaller subatomic particles. When neutons and protons get get close to each other they convert particles and bond together. This occurance is called The Strong Force.

What is nacl monosaccharide disaccharide organic or inorganic?
bonufazy [111]
<span>inorganic Let's look at the choices and see why they work, or don't work. monosaccharide * Otherwise known as a simple sugar. And NaCl is definitely not a sugar of any type. So this is wrong. disaccharide * Complex sugar. And NaCl doesn't qualify either. organic * A definition of an organic compound is one that has carbon in it. NaCl has sodium and chlorine. No carbon at all, so this isn't the right answer. And I wish that organic was an earlier choice, since the sugars mentioned above are organic compounds. inorganic * This is the only possible choice. Salt is not an organic compound since it doesn't have carbon. So it can't be a sugar either. But it can and is inorganic.</span>

Hurricanes derive their energy from: Group of answer choices the latent heat of condensation. the latent heat of fusion. the lat
klemol [59]

Hurricanes derive their energy from the Latent heat of condensation.

Hence, Option (1) is correct answer.

<h3>What is Latent Heat ? </h3>

The heat that is released or absorbed during a phase change of a substance is known as Latent heat.

<h3>What is Hurricanes ?</h3>

Hurricanes is basically a type of storm called a tropical cyclone. These are intense low pressure areas. Hurricanes derive their energy from the latent heat of CONDENSATION.

Thus from the above conclusion we can say that Hurricanes derive their energy from the Latent heat of condensation.

Hence, Option (1) is correct answer.
