Answer:

An appropriate solvent is <u>only in the fingerprint region. </u>

Explanation:

For scientists to study the infrared spectra of substances in the various states of matter, solutions are usually made with solvents. However, it has been noted that some of these solvents can interfere with the reaction spectra or be absorbed within the range of the solutes. A solution to this problem is using the right solvents with non-interfering infrared spectrum and which have no chemical effect on the solute.

The bands formed by the solvent should also be located in the the fingerprint spectrum. Examples of solvents used to achieve this and which meet up these requirements include, Carbon tetrafluoride and Carbon disulfide.

Which statement best describes the effect of low ionization energies and low electronegativities on metallic bonding?
kramer
The statement that best describes the effect of low ionization energies and low electronegativities on metallic bonding is the first one - the valence electrons are easily delocalized. 
Due to these low energies and negativities, valence electrons can be moved around quite easily and their positions may be altered quite drastically.

A gas has a volume of 52.1 L at 1.55 atm. What is the new volume at a pressure of 2.00 atm?
Deffense [45]

Answer: 40.38 L

Explanation:

Formula: P1V1 = P2V2

(1.55)(52.1) = (2.00)(x)

80.755 = 2x

40.38 = x
