Equations for combustion will change with the type of fuel used. For example, the complete combustion of pentane is (C5)(H12) + 3(O2) --> 5(CO2) + 6(H2O). The complete combustion of ethanol is (C2)(H5)(OH) + 3(O2) --> 2(CO2) + 3(H2O).
Pure, elementals Hydrogen is notated as H2.
Hydrogen is one of the seven (Hydrogen, Nitrogen, Oxygen, Chlorine, Bromine, Iodine, Fluorine) diatomic elements. These elements occur as a 2 atomic molecule in nature.
Not sure exactly what you're asking, but hopefully this helps:
Hydrogen is a diatomic molecule so in nature exists as H2. That would be the formula for hydrogen.
If electricity is channeled through water, a decomposition reaction, resulting in the production of oxygen and hydrogen, will occur. This is the balanced equation for that reaction:
2H2O --> 2H2 + O2
(oxygen is also a diatomic molecule, so it also has to be written as O2 instead of just O)
2H2 + O2 => 2H2O + heat
Since the question was on combustion of hydrogen, it would have been better to include the amount of heat released.
The combustion reaction for hydrogen is 2H2 + O2 --> 2H2O
2H2 + O2 --> 2H2O
2h2 + o2 = 2h2o
C3H8 + 5 O2 -------> 3 CO2 + 4H2O
2h2o --> 2h2 + o2
The chemical equation is:2 NaHCO3---------------------Na2O + 2 CO2 + H2O
The chemical equation is:2 Al(OH)3 = Al2O3 + 3 H2O
The chemical reaction is: NH4NO3 + NaOH -----→ NH3 + H2O + NaNO3
This is not a decomposition reaction.
The balanced equation for the reaction between MgO and H2O is MgO + H2O -> Mg(OH)2.
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
Decomposition
The chemical equation is:2 NaHCO3---------------------Na2O + 2 CO2 + H2O
The chemical equation is:2 Al(OH)3 = Al2O3 + 3 H2O
The balanced chemical equation is: MgO + H2O → Mg(OH)2 The product formed in this reaction is magnesium hydroxide.
A chemical reaction that breaks down a compound into simpler products is a decomposition reaction. For example, when electrolyzed, water will be decomposed into hydrogen and oxygen gas. Decomposition reactions involve one reactant and multiple products.
The chemical equation is:SO2 + H2O ↔ (HSO3)- + H+The acid is hypothetic.
H2o + hpo3 H3PO4----P2O5+H2O
The chemical reaction is: NH4NO3 + NaOH -----→ NH3 + H2O + NaNO3
The name is potassium carbonate, but there's NO (balanced) equation for just one compound. An equation is about a reaction e.g. synthesis or decomposition of K2CO3. This should be clearly stated in a question. Please rephrase it.
The chemical reaction is:SO2 + 2 H2 = 2 H2O + S
CaCO3 + 2HCl --> CaCl2 + CO2 + H2O
