Answer:
The decreasing order of bond length in the carbon - carbon bonds will be:

Explanation:
Bond length is defined as average distance between two nuclei of bonded atoms in a molecule.Bond length is inversely proportional to the number of bonds present between two atoms.
...[1]
Bond energy is defied as amount of energy required to break apart the bond of 1 mole of molecule into their individual atom. Bond energy is directly proportional to the number of bonds present between two atoms.
..[2]
From [1] and [2]:

hybridized
hybridized
hybridized
Extent of overlapping of orbitals in these hybridization;

Higher the overlapping of orbital more closer will be both atoms to each other and shorter will be the bond lenght.
So, the decreasing order of bond length in the carbon - carbon bonds will be:

Answer:
initial temperature=
Explanation:
Assuming that the given follows the ideal gas nature;






mole of gass will remain same at any emperature:

putting all the value we get:

initial temperature=
Answer:
(a) a = 5.08x10⁻⁸ cm
(b) r = 179.6 pm
Explanation:
(a) The lattice parameter "a" can be calculated using the following equation:
<em>where ρ: is the density of Th = 11.72 g/cm³, N° atoms/cell = 4, m: is the atomic weight of Th = 232 g/mol, Vc: is the unit cell volume = a³, and </em>
<em>: is the Avogadro constant = 6.023x10²³ atoms/mol. </em>
Hence the lattice parameter is:

![a = \sqrt[3]{1.32 \cdot 10^{-22} cm^{3}} = 5.08 \cdot 10^{-8} cm](https://tex.z-dn.net/?f=%20a%20%3D%20%5Csqrt%5B3%5D%7B1.32%20%5Ccdot%2010%5E%7B-22%7D%20cm%5E%7B3%7D%7D%20%3D%205.08%20%5Ccdot%2010%5E%7B-8%7D%20cm%20)
(b) We know that the lattice parameter of a FCC structure is:

<em>where r: is the atomic radius of Th</em>
Hence, the atomic radius of Th is:

Answer:
chlorine, fluorine, bromine, iodine, Xenon, and radon
During a lifetime, a heart beats 3.1 x 10^9 times and it beats 91 times in one minute.
Thus, we can use cross multiplication to determine the number of minutes in the person's lifetime as follows:
number of minutes in person's lifetime = (3.1 x 10^9) / 91 = 34.0659 x 10^6 min
One year has 365.25 days (disregarding leap). Each day has 24 hours and each hour has 60 minutes.
Therefore,
one year = 365.25 x 24 x 60 = 525960 minutes
We can now use cross multiplication to determine the number of years of a person's lifetime as follows:
number of years = (34.0659 x 10^6 x 1) / 525960 = 64.76899 years.
