2H2,g + O2,g --> H2Ol
The balanced chemical equation for the formation of water from two hydrogen molecules and one oxygen molecule is: 2H₂ + O₂ → 2H₂O.
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
The chemical equation for hydrogen to water vapor is not possible as stated. In order for hydrogen to form water in any physical state, it must combine with oxygen. The following are the word equation and the chemical equation for hydrogen and oxygen combining to form water. Hydrogen gas plus oxygen gas produces water. 2H2 + O2 --> 2H2O
The chemical equation Mg + H2S -> MgS + H2.
I'm assuming you mean water; which is H2O (2 hydrogen and 1 oxygen atom)
The chemical formula (not equation) of sodium hydrogen sulfite is NaHSO3.
2 oxygen, 4 hydrogen
The chemical equation for the formation of water from hydrogen and oxygen is: 2H2 + O2 → 2H2O. This equation shows that two molecules of hydrogen gas (H2) react with one molecule of oxygen gas (O2) to form two molecules of water (H2O).
The balanced chemical equation for the formation of water from two hydrogen molecules and one oxygen molecule is: 2H₂ + O₂ → 2H₂O.
The chemical equation for the reaction between sulfur and hydrogen is: S + H2 → H2S. This reaction forms hydrogen sulfide gas.
The chemical equation is 2H2(g) + O2 → 2H2O(l). Two moles of hydrogen reacts with one mole of oxygen to form two moles of water.
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
KI + H2SO4 (concentrated) --> HI + KSO4
The word equation for the formation of hydrogen gas is "Hydrogen gas is produced by the reaction of a metal with an acid."
The chemical equation for the formation of ammonia is N2 + 3H2 → 2NH3. This equation represents the reaction between nitrogen gas (N2) and hydrogen gas (H2) to produce ammonia (NH3). The balanced equation shows that one molecule of N2 reacts with three molecules of H2 to form two molecules of NH3.
The chemical equation for the reaction of oxygen reacting with hydrogen to yield water is 2H2 + O2 → 2H2O.
When hydrogen bromide reacts with water, it forms hydrobromic acid, which can be represented by the chemical equation HBr + H2O → H3O+ + Br-. This reaction involves the dissociation of hydrogen bromide into H+ and Br- ions in solution.
