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.

3. Determine the limiting reagent.
To determine the limiting reagent divide the number of moles by the stoichiometric coefficient of each compound:
- For the :
- For the :
As the is the smalles quantity, this is the limiting reagent.
4. Calculate the mass in grams of the barium white pigment produced from the limiting reagent.
5. The percent yield for your synthesis of the barium white pigment will be calculated using the following equation:
Percent yield =
Percent yield =
The real yield is the quantity of barium white pigment you obtained in the laboratory.
