A star is made up of approximately 75% hydrogen and 24% helium. The other 1% is usually metals of some degree or another depending on the particular star.
The chemical reaction involved in the mixture of hydrogen and oxygen to form water is: 2H O 2HO
No. When in the form of water, hydrogen and oxygen form a compound, which is a pure substance.
it is a compound carbon hydrogen and oxegen atoms combined form it
When dilute hydrochloric acid is added to a mixture of iron and sulfur, the reaction produces hydrogen sulfide gas and iron chloride as products. The iron in the mixture will react with the acid to form iron chloride, while the sulfur will combine with the hydrogen from the acid to form hydrogen sulfide gas.

No - a star would not be a pure substance. Our understanding of how stars function includes a continuous fusion of hydrogen to form helium and, depending on the star, possibly further fusion of the helium into even heavier elements. Once formed, these heavier elements do not just go away or change back into helium so stars will always be composed of a mixture of hydrogen and the byproducts of fusion.
The sun is a star made primarily of hydrogen and helium gases undergoing nuclear fusion, making it a homogeneous mixture of elements.
You have a mixture that can be easily ignited to form water vapor.
When gaseous hydrogen and gaseous chlorine are mixed each other, they react vigorously to form hydrogen chloride (HCl). The only way to separate elements from the gas HCl is electrolysis where chlorine is discharged at cathode and the other at anode.
The most common element in a young star is hydrogen. During the star formation process, vast amounts of hydrogen gas collapse under gravity to form a new star. This hydrogen fuel is what powers nuclear fusion reactions in the star's core, creating energy and sustaining the star's brightness.

Hydrogen peroxide is a compound, but it is too unstable to exist in pure form undermost conditions. Therefore, when encountered in a laboratory or during medical treatment, hydrogen peroxide is almost always a mixture with water.
