Question

Water contains the elements oxygen and hydrogen. Where did the hydrogen in the water come from in this reaction?​

Answer 1

Answer:

hydrogen is all ready present in it .

Explanation:

hydrogen means water

Answer 2

The hydrogen atoms in water (H2O) generally come from dihydrogen (H2) gas reacting with dioxygen (O2) gas in a process called hydrogen combustion or hydrogen oxidation.

2 H2 + O2 → 2 H2O

• In nature, hydrogen can also be produced by various chemical and biological processes, such as B. the decomposition of organic matter, the reaction of water with certain metals and the activity of certain bacteria.
• In most cases, however, the hydrogen we use for industrial and energy applications comes from natural gas, a fossil fuel that mainly contains methane (CH4).
• Hydrogen from natural gas is separated and purified by a variety of methods including steam methane reforming, electrolysis, and coal gamification.
• Once hydrogen is produced, it can be stored, transported, and used for a variety of purposes, including fuel cells, hydrogenation reactions, and ammonia production.

Hence, the hydrogen atoms in water (H2O) generally come from dihydrogen (H2) gas reacting with dioxygen (O2) gas in a process called hydrogen combustion or hydrogen oxidation. This reaction is commonly known as "burning" hydrogen.
