The activation energy barrier. Combining H atoms and O atoms into water releases a large amount of energy, but breaking up H2 molecules and O2 molecules into H and O atoms requires a large (but not as large) amount of energy. You need to supply sufficient energy to get things started, after which it's generally self-sustaining (and very rapidly so; a stoichiometric mixture of H2 and O2 is quite explosive once ignited).
H2 +Cl2---------------->2HCl Since H2 and Cl2 react in 1:1 mole ratio the number of moles of H2 reacting is equal to the number of moles of Cl2 which is equal to 0.213
Three: The reaction equation is N2 + 3 H2 -> 2 NH3
decomposition
The balanced chemical equation shows that 1 mole of oxygen reacts with 2 moles of hydrogen to form water. Therefore, if you have 1.42 moles of hydrogen, you would need 0.71 moles of oxygen to react with it in this reaction.
Lithium does react with HCl (with a lowercase L) to produce lithium chloride (LiCl) and hydrogen gas (H2)
nacl2+h2
H2 and NO can react to form H2O and N2. This reaction occurs at high temperatures in the presence of a catalyst.
H2 +Cl2---------------->2HCl Since H2 and Cl2 react in 1:1 mole ratio the number of moles of H2 reacting is equal to the number of moles of Cl2 which is equal to 0.213
Yes. Sodium will react vigorously with water. The reaction is very exothermic and may even cause fire. 2Na + 2H2O ---> 2NaOH + H2
Three: The reaction equation is N2 + 3 H2 -> 2 NH3
Yes. MgCl2 is formed with the evolution of H2 gas
decomposition
Sodium hydroxide does not react with hydrogen gas.
No. Simply mixing hydrogen and oxygen will not get you water. You must burn the mixture.

h2 o
Hydrogen reacts with oxygen when it burns. H2 + O2 --> H2O
