Boyle’s law= pressure and volume are inversely related. When air flows in Volume increases and pressure decreases, when air flows out the intrapulmonary pressure equilibrates with atmospheric pressure.

Covalent bonds in a molecule absorb radiation in the IR region and vibrate at characteristic frequencies.
vazorg [7]

Answer:

Frequency=1.6\times 10^{12}\ Hz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength


c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 188 μm

Also, 1 μm = 10^{-6} nm

So,  

Wavelength = 188\times 10^{-6} m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{188\times 10^{-6}}\ Hz

Frequency=1.6\times 10^{12}\ Hz

Draw the addition product formed when one equivalent of hcl reacts with the following diene.
pashok25 [27]

Answer:

                    Major Product = 4-chloro-4-methylcyclohex-1-ene

Explanation:

                     Alkene are the class of organic compounds which contain one or more double bonds between two carbon atoms. Alkenes are considered most reactive among the unsaturated hydrocarbons and they undergo <em>addition reactions</em> due to high electron density around the double bonds.

                      In given question it is written that we are provided with one equivalent of HCl while, our compound contains two double bonds (diene) so in selected starting material the HCl will be added across (hydrohalogenation reaction) the substituted double bond because it will give a more stable carbocation (<u><em>tertiary carbocation</em></u>) during the reaction course. Hence, as shown in reaction scheme 4-chloro-4-methylcyclohex-1-ene will be the major product.

Why is urbanization contributing to pollution? People in urban areas strip the soil of nutrients and make it difficult to grow c
slavikrds [6]

We have to know how urbanization causes pollution.

The reason is: People in urban areas consume more energy, food, and water.

Urbanisation is one of the major problem towards pollution. The smoke from automobiles, factories and power generators make air unhealthy. Also chemical spills and other toxic gases contaminate in air.

The mixing of toxins in the soil is polluting soil which disturbs eco-system.

The high density population in urban area consume more energy , food and water which causes pollution.
