Which concept describes the formation of four equivalent, single, covalent bonds by carbon in its compounds that resembles metha

Montano1993 [528]

Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.

Predict (to 3 sig figs) the isochoric specific heat of gaseous SF6 (molar mass 146.06 g/mol) at 1200 K, assuming that at this te

bazaltina [42]

Explanation:

As it is known that $SF_{6}$ molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.

$C_{v} = \frac{3}{2}R + \frac{3}{2}R + (3 \times 7 - 6)R$

= $\frac{3}{2}R + \frac{3}{2}R + 15R$

= 18 R

Also, $C_{V} = M \times C_{v}$

where, $C_{V}$ = molar heat capacity

M = molecular mass

$C_{v}$ = specific heat

Hence, calculate the value of $C_{v}$ as follows.

$C_{V} = M \times C_{v}$

$8 \times 8.314 \times 10^{7} = 146.06 \times C_{v}$

$C_{v} = 10.2 \times 10^{6} erg. K^{-1}. gm^{-1}$

This means that value of isochoric specific heat is $10.2 \times 10^{6} erg. K^{-1}. gm^{-1}$ .

Yes, we have to assume ideal gas behavior because for ideal gas:

dU = $nC_{v}dT$

Whereas for real gases " $\frac{an^{2}}{V^{2}}$ " has to be added here.
