The monomer from which the very common commercial polymer poly vinyl chloride is vinyl chloride with the formula, CH₂Cl = CH₂Cl. The PVC is formed by addition polymerization.
What is polymerization ?Polymerization is the process of combination of smaller molecules or compounds in large number to form macromolecules or polymers. There are a lot of polymers that we are using daily in the form of bags, plastics, bottles etc.
Among the common polymers we use PVC or poly vinyl chloride is very essential commercial polymer. The monomer of PVC is vinyl chlorides.
The polymerization of n vinyl chloride to form polyvinyl chloride is given below.
[tex]\rm n CH_{2}Cl = CH_{2}Cl \rightarrow (-CH_{2}Cl - CH_{2}Cl -)__{n}[/tex]
The polymerization of vinyl chloride is taking place through addition mechanism. The vinyl chloride monomer repeatedly add one by one to form the polymer.

Explanation:
At body temperature, 2404 J is required to evaporate 1 g of water. After vigorous exercise, a person feels chilly because the body is giving up heat to evaporate perspiration. A typical person perspires 25 mL of water after 20 minutes of exercise. How much body heat is used to evaporate this water
Answer: - 1.45 kJ
Explanation:
Using q = m x C x (ΔT)
Given : m = 3.8 g , C = 0.900 J/g°C, = -(450-25)°C = -425°C (Since final temperature is less than the initial, the sign is negative)
q = (3.8 g) x (0.900 J/goC) x ( -425 °C)
= -1453.5 J
= -1.45 kJ
Note that negative sign of q indicates that this much heat is released, when the metal cools down.

what is emission spectrum and absorption spectrum?
Answer:
When matter interact with EMR then spectrum is obtained. We can understand both spectra using Bohr's hydrogen spectrum. let's have a look on Bohr's hydrogen spectrum what does it say. It says when a electron gains energy it moves from one energy level to other(lower to higher) which is Absorption phenomenon. When the electrons returns from excited state to ground state they emits several spectral lines. this spectrum is called as emission spectrum. inshort the
Emission spectrum is spectrum of electromagnetic radiations that were emitted from the higher energy state(Excited state) to lower energy state(Ground state). and study of emission spectrum is known as AES (Atomic Emission spectroscopy).
When an atom or ion is subjected to EMR, it absorbs certain level of radiations, and when this absorbed energies are studied under spectroscopy they are plotted as absorption spectrum, and study of Absorption spectrum is known as AAS (Atomic Absorption spectroscopy).

Explanation:
If you have a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2, what is the resulting temperature in K
The resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.
How to calculate temperature?The temperature of a given gas can be calculated by using the ideal gas law equation:
PV = nRT
Where;
P = pressure V = volume n = number of molesR = gas law constantT = temperatureno of moles of Cl2 = 76.33g ÷ 70.91g/mol = 1.08mol
2.35 × 1.2 = 1.08 × 0.0821 × T
2.82 = 0.088T
T = 2.82/0.088
T = 31.8K
Therefore, the resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.

How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction?.
Answer:
In fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. Thus, noncompetitive inhibition acts by reducing the number of functional enzyme molecules that can carry out a reaction.

what volume of N2 is required to convert 5.0L of hydrogen gas to ammonia? assume that all gases are at the same temperature and pressure and that the reaction is complete
Answer:
Approximately [tex]1.7\; {\rm L}[/tex].
Explanation:
Nitrogen [tex]{\rm N_{2}}\, (g)[/tex] reacts with hydrogen [tex]{\rm H_{2}}\, (g)[/tex] at a [tex]1:3[/tex] ratio to produce ammonia [tex]{\rm NH_3}\, (g)[/tex]:
[tex]{\rm N_{2}}\, (g) + 3\; {\rm H_{2}}\, (g) \to 2\; {\rm NH_{3}}\, (g)[/tex].
The ratio between the coefficient of [tex]{\rm N_{2}}\, (g)[/tex] and the coefficient of [tex]{\rm H_{2}}\, (g)[/tex] is:
[tex]\begin{aligned}\frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
Under the ideal gas assumptions, the same ratio would apply to the volume of [tex]{\rm N_{2}}\, (g)[/tex] and [tex]{\rm H_{2}}\, (g)[/tex] in this reaction:
[tex]\begin{aligned}\frac{V({\rm N_{2}})}{V({\rm H_{2}})} = \frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
[tex]\begin{aligned}V({\rm N_{2}})= \frac{1}{3}\, V({\rm H_{2}})\end{aligned}[/tex].
Given that [tex]V({\rm H_{2}}) = 5.0\; {\rm L}[/tex]:
[tex]\begin{aligned}V({\rm N_{2}}) &= \frac{1}{3}\, V({\rm H_{2}}) \\ &= \frac{1}{3}\times 5.0\; {\rm L} \\ &\approx 1.7\; {\rm L}\end{aligned}[/tex].
(Rounded to [tex]2[/tex] significant figures.)
