Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
Answer:
Because of the influence of colonial rule. There is also another reason: to unify all languages.
Answer is C it encourages scientific research
<em>:-)</em><em> </em><em>In chemistry, the history of molecular theory traces the origins of the concept or idea of the existence of strong chemical bonds between two or more atoms. The first people to suggest that the world was made of atoms were Democritus and Leucippes(most people of this time believed the world was made from the elements fire, water, earth and wind). However who actually ‘discovered’ is unclear because conceptions happened way before they were seen so it is hard to debate.</em>

<em>The modern structure of benzene was first proposed by Kekule in 1865, then confirmed by Kathleen Longsdale: a crystallographer. He was the first known person to use a model similar to the one we use today- evident in the double carbon bonds .</em>

<em>In 1718, Etienne Francois Geoffrey produced what is known as an affinity table. It’s purpose was to show all the elements that could be combined to make molecules. This shows us that anybody after this can be ruled out because these molecules were scientifically proven to exist before them.</em>
===========================================
<em>However, in the 17th century we finally get our answer. In 1661, Robert Boyle created The Sceptical Chymist, which proved, and named, molecule’s existence.</em>
