A mass spectrum of an organic compound shows the relative abundances of M to be 40.58% and M 1 to be 7.022%. Assuming the peaks
sveticcg [70]

Answer:

The number of carbon atoms in the organic compound is 16.

Explanation:

The relative intensity of M + 1 peak (relative to M = 100) in organic compounds can be predicted by the following formula:

[M + 1] = (number of C x 1.07) ---------------------------------------------------- (1)

This formula can also be used to determine the number of carbon from the given intensity. But first, the intensity of [M + 1] relative to [M] = 100 needs to be determined, for which, consider the following calculations,

[M+1]=(\frac{M+1}{M}) (100)

[M+1]=(\frac{7.022}{40.58}) (100)

[M+1]=17.30

Using equation 1 we get,

number of C=\frac{[M+1]}{1.07}

number of C=\frac{17.3}{1.07}\\number of C = 16.168

or number of C = 16

The remaining value, 0.168, can be due to the isotopes of hydrogen and oxygen in the organic compound.

1. What role does energy play in sound?
Lilit [14]

Answer:

1. Sound is a energy (mechanical)produced by vibrating objects and sound energy is movement of energy through particles.

2.Space occupied by the substance

3.<u>Propagation</u> of <u>Sound Wave</u> and <u>particles of the medium</u>

4.High-Frequency(Ultrasonic wave)

Explanation:

1.Sound is the form of energy which causes sensation of hearing to our ear.It is produce by vibrating objects. When the objects vibrate(to and fro motion) ,they pushes the particles of medium creating the region of high density called compression .When the particles moves backward ,they creates a region of low density called Rarefaction.This pattern repeats indefinitely.

2.Volume is the quantity of three dimensional space occupied by substances like solid,liquid and gases. The SI unit of volume is

m^{3}

In metric system unit of volume is liter

3. Longitudinal Waves: Waves in which displacement of the medium particles are parallel(in the same direction) to the propagation of wave.

Sound wave is longitudinal wave.Hence its particles moves in the same direction as the wave (energy)travel.

4.Frequency: The number of times sound wave passes a given point in one second.Its SI unit is Hertz(Hz).

Frequency of vibration decides the Pitch of the sound waves producing them.

A sound wave of High Pitch means it is oscillating rapidly(at high speed).These are also called Ultrasonic waves. These have frequency more than 20000 Hz. Human being can't hear ultrasonic waves.

Describe the structure of ammonium lauryl sulfate. Refer to the given diagram. Your answer should include the type of bonding, t
Mariana [72]

Explanation:

Ammonium lauryl sulfate (ALS) is the common name for ammonium dodecyl sulfate (CH3(CH2)10CH2OSO3NH4). The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates the dissolution of both polar and non-polar materials. ALS is classified as a sulfate ester. It is found primarily in shampoos and body wash as a foaming agent. Lauryl sulfates are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.
