Natalija [7]
The main formula is as follow  is explained in the attached file  (please look at the examples)

the 1,3- butadiene is h2c=ch-ch=ch2, so we have 

sp²             sp²     sp²               sp²
h2c    =     ch   -     ch         =      ch2

<span>the hybridization of the carbon atoms  is </span>sp²  : trigonal planar

How would you distinguish benzoic acid and benzyl alcohol by their infrared spectra?
Vadim26 [7]

The OH peaks in the IR spectra of benzyl alcohol and benzoic acid should be compared and contrasted.

<h3>What is the IR spectra of Benzoic acid?</h3>
  • The right-hand portion of the infrared spectrum of benzoic acid, between wavenumbers 1500 and 400 cm-1, is referred to as the fingerprint region.
  • It results from a special combination of intricately overlapping vibrations of the atoms within the benzoic acid molecule.
<h3>What is the IR spectra of Benzyl alcohol?</h3>
  • A C-Cl bond is frequently shown by a peak at 700.
  • There are a few more peaks at 1500 that are directed at a C=C bond.
<h3>What is IR spectra?</h3>

The percent transmittance (or absorbance) of the radiation through the molecule against the radiation's wave number forms the IR spectrum.

Calculate the MASS if the density is 2.34 g/mL and the volume is 12.50 mL.
AlexFokin [52]

Answer:

<h2>mass = 29.25 g</h2>

Explanation:

The denisty of a substance can be found by using the formula

Density =  \frac{mass}{volume}

Making mass the subject we have

<h3>mass = Density × volume</h3>

From the question

Density = 2.34 g/mL

volume = 12.50 mL

Substitute the values into the above formula and solve for the mass

That's

mass = 2.34 × 12.50

We have the final answer as

<h3>mass = 29.25 g</h3>

Hope this helps you
