Answer:

4.993 ×10⁻¹¹ J

Explanation:

The <em>nuclear binding energy</em> is the energy equivalent to the mass defect.

The <em>mass defect</em> is the difference between the mass of a nucleus and the sum of the masses of its nucleons.

<em>Calculate the mass defect </em>

  16 p = 16 × 1.007 28 u =  16.116 48  u

  16 n = 16 × 1.008 67 u =  16.138 72  u

Total mass of nucleons = 32.255 20 u

             - Mass of S-32 = <u>31.972 070 u </u>

                 Mass defect =  0.283 13   u

Convert the <em>unified atomic mass units to kilograms</em>.

Mass defect

= \text{0.283 13 u} \times \frac{ \text{1.66 06} \times 10^{-27} \text{ kg}}{\text{1 u}}

= 4.700 \times 10^{-28} \text{ kg}

Use Einstein’s equation to <em>convert the mass defect into energy</em>

E = mc^{2}

E = 4.7000 \times 10^{-28} \text{ kg} \times (2.998 \times 10^{8} \text{ m}\cdot\text{s}^{-1})^{2} = 4.224 \times 10^{-11} \text{ J}

How many sigma bonds does CS2 have?
Pie

Answer:

2 sigma bonds

CS2 is called carbon disulphide. The 2 unpaired electrons of each sulphur atom get paired with the 4 unpaired electrons of carbon. But it is a double bond. That is, 2 sigma bonds (sigma s-p , sigma p-p) and 2 pi (πp-p) bonds.
