Infrared (IR) spectroscopy is used to identify functional groups within a molecule. Click on the peak that corresponds to the st

Sergio [31]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct place to click on any of the double peak showing between 2500 and 3000 $cm^{-1}$ on the uploaded question

Explanation:

The group which is being highlighted is an Aldehyde functional group denoted by this structure ( $=C-H$ )

This groups stretch on the infrared spectrometer gives two medium intensities peaks

Its stretch comes at 2820 - 2850 $cm^{-1}$ peak 1

and at 2720 - 2750 $cm^{-1}$ peak 2

So the correct click would be on any of the two peaks between 2500 - 3000 $cm^{-1}$ region

How many moles of NO gas are formed from 2.25 moles of nitrogen?

VikaD [51]

Hey there!

A mole is measured in atoms, molecules, particles. It's kind of a loose sort of measurement, just unit of the substance.

Since there is a ratio of 1 to 1 nitrogen to oxygen, there will be the same amount of molecules as atoms of nitrogen.

2.25 moles of NO gas are formed from 2.25 moles of nitrogen.

Hope this helps!

Consider the anion whose charge is 2- and whose electron configuration is identical to argon. what is the symbol for this anion

AleksAgata [21]

If the ion is negatively charged, anion, it means that it gains two electrons from its surroundings. The number of electrons of an argon (neutral atom) is 18. Two of the electrons in our anion is from the surrounding, so originally it only has 16 electrons.

In the periodic table, the 16th element is sulphur. The chemical symbol of sulphur is S. Thus, the anion is the negatively charged sulphur with chemical symbol of S2-.
