Before a star is a star, it is an enormous cloud of
gases
As the nuclei meld, a smidgen of their matter vaporizes
into energy
It pushes on the star's outer gases, which flow outward
in giant surges of heat and light.
Tighter and tighter the material contracts, crunching in
so fast and so hard that it is destroyed.

before a star is a star, it is an enormous cloud of gasses.

Explanation:

If you read the article, you would find in one of the paragraphs that it talks about stars and how they are balls of gasses before they are stars.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
