Chlorine gas (cl2) forms when two chlorine atoms share an electron. what type of bonding is present in chlorine gas?
2 answers:
Explanation:
When a chemical bond is formed by sharing of electrons then it is known as a covalent bond.
A covalent bond is always formed between two non-metals.
For example, atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.
As a result, it needs one more electron to complete its octet. So, when it chemically combines with another chlorine atom then there will occur sharing of electrons.
Hence, is formed which is a covalent compound.
On the other hand, when a chemical bond is formed by transfer of electrons from one atom to another then it is known as an ionic bond. An ionic bond is always formed between a metal and a non-metal.
For example, LiCl is an ionic compound.
Thus, we can conclude that in a chlorine gas covalent bonding is present when two chlorine atoms share an electron.

Answer : The pH of buffer is 9.06.
Explanation : Given,
Concentration of HBrO = 0.34 M
Concentration of KBrO = 0.89 M
Now we have to calculate the pH of buffer.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Therefore, the pH of buffer is 9.06.
