Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.

What is the nuclear binding energy of an atom that has a mass defect of 5.0446
notsponge [240]

Answer:

<em>Option C: 4.54 x </em>10^{11}<em> KJ/mol of nuclei</em>

<em>Note: </em>Here in this question option C is not correctly put. It is 4.54 x10^{11} rather than 4.54 x 10^{-123}.

Explanation:

If mass defect is known, then nuclear binding energy can easily be calculated, here's how:

First step is to convert that mass defect into kg.

Mass defect = 5.0446 amu

Mass defect = 5.0466 x 1.6606 x 10^{-27}

Because 1 amu = 1.6606 x 10^{-27} Kg.

<em>Mass defect = 8.383 x </em>10^{-27}<em> kg.</em>

Now, we need to find out it's energy equivalent by using following equation:

Using the equation E = mc²:

where c= 3.00 x 10^{8} m/s²

E = (8.383 x 10^{-27}) x (3.00 x 10^{8})²

E = 7.54 x 10^{-10} J  this energy is in Joules but nuclear binding energy is usually expressed in KJ/mol of nuclei. Let's convert it:

(7.54 x 10^{-10} Joule/nucleus)x(1 kJ/1000 Joule)x(6.022 x 10^{23} nuclei/mol) =  

<em>4.54 x </em>10^{11}<em> kJ/mol of nuclei .</em>

E = <em>4.54 x </em>10^{11}<em> kJ/mol of nuclei .</em> So, this is the nuclear binding energy of that atom, which is option  C.

<em>Note:</em> Here in this question option C is not correctly put. It is 4.54 x10^{11} rather than 4.54 x 10^{-123}

Answer asap with at least 3 or more sentences!
mixas84 [53]

Answer:

no.

Explanation:

The reason this has

never happened is due to the source of magnetic fields:  moving electric

charges.  When electric charges (e.g. electrons) move in circles, they

produce a magnetic field.  In a piece of iron, it is very easy to line up

these circles, getting all the little magnets to work together as one big

magnet.

For each of these circles, one side is the north pole and one side is the

south pole.  Since each circle has two sides, each circle has a north and a

south pole.  Even the smallest possible magnets (spinning electrons) have a

north and a south pole.
