Chemical Equation For Hydrogen
Hydrogen is the lightest body, has no color or taste, is active, and participates in all kinds of changes. The formula shows the change of hydrogen in the reaction.
As the saying goes, hydrogen and oxygenation, when burned, produce water. The method of transformation is: dihydrogen and monooxygen, burn to produce two water, that is, $2H_ {2} + O_ {2}\ stackrel {ignited }{=\!=\!=} {2} O $. Among them, hydrogen burns in oxygen, the fire is light blue, and it emits huge heat. The state of water changes from an invisible gas to a tangible liquid, which is an important transformation of hydrogen.
There is also hydrogen and chlorine, which react violently under light. The reaction is: hydrogen and chlorine combine to form hydrogen chloride, $H_ {2} + Cl_ {2}\ stackrel {light }{=\!=\!=} 2HCl $. This reaction is rapid, hydrogen chloride is formed, and it is very important for industrial acid production.
Hydrogen is also useful in metallurgy. If hydrogen is used to reduce copper oxide, the reaction is: hydrogen and copper oxide, hot and copper and water, $H_ {2} + CuO\ stackrel {\ Delta }{=\!=\!=} Cu + H_ {2} O $. Hydrogen takes away the oxygen of copper oxide, causing copper to precipitate and showing its reduction properties.
The method of hydrogen transformation shows that it changes in different situations, and is of extraordinary significance in chemistry and industry. It is valued by everyone, and it has endless exploration and infinite functions.
