Classifying Chemical Reactions
Single Replacement Reactions
It is a reaction in which a more active metal displaces another less active metal in a compund
K + NaCl ---> KCl + Na
Cl2 + 2NaCl + Br2
Fe + CuSO4 ---> FeSO4 + Cu
Double Replacement Reactions
In a double-replacement reaction, two ionic compounds in aqueous solution switch anions and
produce an insoluable substance
Na2SO4 + SrCl2 ---> 2NaCl + SrSO4
HCl + NaOH ---> NaCl + H2O
AgNO3 + 2HCl ---> AgCl2 + NO3H2
It is the reaction of an acid and a base
The products of this reaction are a salt and water.
Acid + Base --> Salt + Water
2 NaOH + H2CO3 --> N2CO3 + 2 NaOH
H3PO4 + 3 NaOH --> Na3PO4 + 3H20
NaOH+H2SO4 ---> Na2SO4+H2O
Decomposition Reactions(Analysis Reactions)
In a decomposition reaction, a single compound is broken into simpler substances.
Decomposition: AB ---> A + B
Note:Heat is usually required(endothermic reaction)
H2O ---> H2 + O2
2HgO ---> 2Hg + O2
ZnCO3(s) ---> ZnO(s) + CO2(g)
It is the reaction of simpler substances coming together to form more complex compounds.
Combination: A + B ---> AB
2Mg + O2 ---> 2MgO + Heat
In some combination reactions, heat may also occur as an outcome.
MgO + CO2 ---> MgCO3
Ba + F2 ---> BaF2
Fuel burns with oxygen, produces carbon dioxide, water and heat or flame.They are usually rapid solutions that produce flames and most of them involves oxygen as a reactant.
Note: Rusting of iron and blackening of silver is an example of slow burning
CH4(g) + 2O2(g) ---> CO2(g) + H2O(g)
2C3H8 + 5O2 ---> 2CO+ 4C+ 8H2O
2Mg(g) + O2(g) ---> 2MgO(g)
