Question

Most stars spend the majority of their lives converting core hydrogen to what? Select all that apply.

a. iron
b. silicon
c. helium
d. carbon E. oxygen F. energy

Answer 1

Answer: The correct answer is Option c.

Step-by-step explanation:

Hydrogen is the main element that is present in most of the stars. The stars undergo nuclear fusion reaction.

Nuclear fusion reactions are the reactions in which two smaller nuclei combines or fuses together to form a single heavier nuclei.

The reactions which undergo in most of the stars are:

`_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}`

The overall equation for the above reactions is:

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

The product of the reactions is helium nuclei.

Hence, the correct answer is Option c.
