This is a chemical reaction known as a combustion reaction, where hydrogen sulfide (H2S) and oxygen (O2) react to form water (H2O) and sulfur (S).
decomposition
This reaction is a decomposition reaction where a compound breaks down into simpler substances. In this case, potassium chlorite (KClO2) breaks down into potassium chloride (KCl) and oxygen gas (O2).
The reaction is 2Mg + O2 ----> 2MgO Mainly it is a Composition reaction (also called as combination or syntesis reaction). But also catogrised in redox reaction & combution reaction.
This reaction is:2 CO2 = 2 CO + O2
Type of reaction for S8 + O2
The reaction HgO -> Hg + O2 is a decomposition reaction, where HgO breaks down into its constituent elements mercury (Hg) and oxygen gas (O2).
decomposition reaction
NaCl-----------------Na+ + Cl-is a dissociation reaction.
combustion reaction
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
4 Na + O2 → 2 Na2O2 Na + O2 → Na2O2
This is a chemical reaction known as a combustion reaction, where hydrogen sulfide (H2S) and oxygen (O2) react to form water (H2O) and sulfur (S).
decomposition
If you meant to type 2CO + O2 -> 2CO2, then this type of reaction is called synthesis because 2 or more reactants are combining to create one product.
This is an oxidation reaction of N from -3 (in NH3) to +2 (in NO) oxidation value. 4 NH3 + 5 O2 --> 6 H2O + 4 NO
This reaction is a decomposition reaction where a compound breaks down into simpler substances. In this case, potassium chlorite (KClO2) breaks down into potassium chloride (KCl) and oxygen gas (O2).
