Lewis Structure of
Oxygen Difluoride is sketched as....
Step 1: Calculate the
total number of valence electrons present in OF₂. This is done by adding all valence electrons of each element. i.e...
Valence e⁻s of Oxygen = 6
Valence e⁻s of Fluorine-1 = 7
Valence e⁻s of Fluorine-2 = 7
------------
Total Valence e⁻s
20Step 2: Draw central element (O) in center surrounded by fluorine atoms. Now, sketch a single bonds between O and both F atoms. Now, subtract 2 electrons per single bond from total valence electrons.. i.e..
Total Valence e⁻s = 20
2 single bonds (2 × 2) = 4
-----------
16Now, distribute remaining 16 electrons on each element to complete its
octet starting from most electronegative element.
Lewis structure of OF₂ is as follow,
Answer: A polar bond occurs when the charge distribution between atoms in a bond is unequal. A polar compound, or a polar molecule, happens when the opposing ends of a molecule are not symmetric in charge meaning one end is negative and one end is positive.
Explanation:
CHCl3 is a polar molecule because the single hydrogen atom does not cancel out the three chlorine atoms bonded to the carbon, it creates a negative charge on one side and a positive on the other. CCl4 is a non-polar molecule because all four of the atoms in the tetrahedral are chlorines, causing them to cancel each other out. It is possible to have polar bonds within non-polar molecules.
Total mass stays the same

The first example of diffusion is smoking a cigarette when u light it it spreads through the air.
The second example is lighting a candle in a room it the smoke spreads through the air.
Smoke can be very bad for the air and the people around because it can cause many problems with your breathing.
