2Al + 3Cl2 ----> 2AlCl3 is a chlorination reaction but more generically it is a Redox reaction. The Aluminum is oxidized from oxidation state 0 to 3. The Chlorine is reduced from oxidation state 0 to -1.
This reaction is used in the manufacture of iron and can be considered as a redox reaction, where carbon (or generally coke) is the reducing agent.
2FeO + C ----> 2Fe + CO2
The reaction is:
2 Al + Fe2O3 = Al2O3 + 2 Fe
This is a reduction reaction.
aerobic cellular respiration
O2
Co2+ + 2SO4
Not a combustion reaction. Combustion reactions produce CO2 and H2O.
I assume you were looking to balance the reaction: CH4 + 2O2 --> CO2 +2H2O
Single replacement ex: 2K + 2HCl --> 2KCl + H2 Double replacement ex: Na2SO4 + 2CaCO3 --> Na2CO3 + CaSO4 Combustion ex: H2CO3 --> H2O + CO2 Synthesis ex: 2Fe + O2 --> 2FeO
the corrosion elements are CO2 and H2O. but rust is ferric oxide. so simple equation is, 2Fe + 3O2 = Fe2O3 but oxygen directly does not react with iron actual mechanism is, CO2 + H2O = H2CO3 2Fe + H2CO3 = Fe(HCO3)2 + H2 2H2 + O2 = 2H2O 2Fe(HCO3)2 = Fe2(CO3)3 + CO2 + 2H2O Fe2(CO3)3 = Fe2O3 + 3CO2
synthesis reaction occurs when elements or compounds combine to form a new, more complex compound. a few examples of this in its form is: 2F+O2= 2FEO 6H+O2= Ag5o
Combustion reaction.
Fe2O3 + 3CO -----> 2Fe + 3CO2
The equation CaCO3 -> CaO + CO2 is an example of a decomposition reaction.
aerobic cellular respiration
decomposition
The reaction is:H2O + CO2 = H2CO3
The reaction is:MgCO3 = MgO + CO2
Bicarbonate reaction CO2 + H20 ⇋ H+ + HC03-
This reaction is:2 CO2 = 2 CO + O2
