<span>Xe = VIII = 8 valence electrons
F = VII = 4 (7 ve) = 28 valence electrons</span>
total ve = 8 + 28 = 36 ve
<span>36 - 4(2) = 28 ve
(there are 2 electrons in each bond x 4 bonds)</span>
<span>28 - 4(6) = 4
(We assign the remaining electrons to F atoms)</span>
<span>4 - 2(2) = 0
(Therefore 4 electrons left => we have 2 lone pairs)</span>
The steric number = No. of
σ bonds + #lone pairs
= 4 σ bonds + 2 lone pairs
= 6 => d²sp³ (6 hybrid orbitals)
<span>4 bonds + 2 lone pairs
=> square planar</span>

<em>The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tube</em><em> </em><em>like structure called the style</em><em>.</em>

A welding torch produces a flame by burning of acetylene fuel then energy released from the acetylene fuel is then used to melt a metal, so transformation of chemical energy into thermal energy takes place.
<h3>What is transfer of energy?</h3>
Energy neither can be produced nor destroyed but it only transfers from one form to other form.
In the question it is given that, burning of acetylene produces energy and this produced energy is a type of chemical energy and then this is used as a thermal energy for the melting of metal.
So conversion of kinetic energy to potential energy, thermal energy to electromagnetic energy and potential energy to chemical is wrong.
Hence transformation of chemical energy into thermal energy takes place.

Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Yet the skin hosts diverse communities of beneficial bacteria, collectively known as the skin microbiota.
