question 80

Multiple Choice

It is believed that two carbon-12 nuclei can react in the core of a supergiant star to form sodium-23 and hydrogen-1.Calculate the energy released from this reaction for each mole of hydrogen formed. Particle Mass (amu) C-12 12.000000
Na-23 22.989767
H-1 1.007825
(1 kg = 6.022 × 10²⁶ amu;
N_A = 6.022 × 10²³ mol^-1;
C = 2.99792458 × 10⁸ m/s)

Definitions:

Seed Drill

An agricultural tool that sows the seeds for crops by positioning them in the soil and burying them to the correct depth, ensuring that seeds are distributed evenly and at optimal depths.

Experience

The knowledge or mastery of an event or subject gained through involvement in or exposure to it.

Productivity

The measure of the efficiency of production often calculated as the ratio of outputs produced to inputs used in the production process.

Constant Returns To Scale

Constant returns to scale occur when a proportional increase in all inputs leads to an equal proportional increase in output, implying efficiency in production.
