Oxygen-16 (15.994915 amu) is synthesized in the sun by fusion of carbon-12 (12. amu) and helium-4
(4.00260 amu). how much energy is released in this nuclear reaction?
3.82 x 10-18 kj
x 10-15
1.20 x 101

1.142 × 10⁻¹⁵ kJ

Explanation:

Total mass of C-12 and He-4 = 12.00000 + 4.00260 = 16.00260 amu

mass of O-16 = 15.99495 amu

Difference in mass = 16.00260 - 15.99495 = 0.00765 amu

The difference in mass 0.00765 is converted into energy.

It is known that,

1 amu = 931.46 MeV

then,

0.00765 amu × 931.46 MeV /amu = 7.1257 Mev

In joule:

1.142 × 10⁻¹⁵ kJ

Because 1 MeV = 1.6 × 10⁻¹⁶ Kj

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
