What is the advantage of using inert gasses in a process?

Chemistry
1 answer:
omeli [17]3 years ago
5 0

Explanation:

Because of non-reactive properties of the inert gases, these gases are useful to prevent the undesirable chemical reactions to happen.

They provide a non-explosive environment. They are also cheap and economical.

Food is packed in the inert gas to prevent rancidity. This also prevents bacteria from growing.  

The gases prevents the chemical oxidation by the oxygen in the normal air.  

Helium is used in oxygen cylinders and also as a coolant in gas cooled reactors.

Place the following covalent bonds in order from least to most polar: a. H-Cl b. H-Br c. H-S d. H-C
timofeeve [1]

Answer:


The Order is as follow,

                                     C-H < S-H < H-Br < H-Cl


Explanation:

                      Polarity depends on the electronegativity difference between two atoms, greater the electronegativity difference, greater will be the polarity of bond and vice versa.


Electronegativity Difference between Hydrogen and other given elements are as follow,


1) C-H;

               E.N of Carbon     = 2.55

               E.N of Hydrogen = 2.20

                                           ------------

               Difference              0.35


2) S-H;

               E.N of Sulfur       = 2.58

               E.N of Hydrogen = 2.20

                                           ------------

               Difference               0.38


3) H-Br;

               E.N of Bromine   = 2.96

               E.N of Hydrogen = 2.20

                                          -------------

               Difference              0.76


4) H-Cl;

               E.N of Chlorine   = 3.16

               E.N of Hydrogen = 2.20

                                           -----------

               Difference               0.96


Hence it is proved that the greatest electronegativity difference is found between H and Chlorine in H-Cl, therefore it is highly polar bond and vice versa.
