Question

This diagram shows the process that powers stars. This process is called?

Answer 1

Answer: The correct answer is Option C.

Explanation:

A star is defined as a fixed point in the night sky which illuminates and is very large. the primary element present in stars is Hydrogen and it continuously changes to helium by a process known as Nuclear fusion reaction. This process releases a huge amount of energy.

Nuclear fusion reaction is defined as the combination of lighter nuclei to form a heavy nuclei. In Stars, hydrogen atoms combine to form a helium atom.

The reactions which takes place in stars follows a series of equations:

$_1^1\textrm{H}+_1^1\textrm{H}\rightarrow _1^2\textrm{H}+_{+1}^0\textrm{e}+\text{energy}\\\\_1^2\textrm{H}+_1^1\textrm{H}\rightarrow _2^3\textrm{He}+\text{energy}\\\\_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0\textrm{e}+\text{energy}$

Overall reaction for the above series of reactions is given by:

$4_1^1\textrm{H}\rightarrow _2^4\textrm{He}+2_{+1}^0\textrm{e}+\text{energy}$

Hence, the correct answer is Option C.
