Combination Reactions
3 H2 + N2 → 2NH3
hydrogen + nitrogen → ammonia
A coupling reaction A type of reaction in which 2 or more reacting elements or compounds combine to form a product compound. X + Y → can be represented by an equation like
MgO + CO2 → MgCO3
magnesium oxide+ cardon dioxide → magnesium carbonate
2 Na + Cl2 → 2 NaCI
sodium + chlorine → sodium chlorine
Decomposition reaction
Ferric hydroxide → ferric oxide + water
2 H2O → 2H2 + O2
2 Fe(OH)3 → Fe2O3 + 3 H2O
water → hydrogen + oxygen
Chemical weathering or chemical degradation is the process of simplifying a single chemical entity into two or more parts. Chemical weathering is often considered and defined as the opposite of chemical synthesis. In short, the chemical reaction in which two or more products are formed from a single reactant is called a decomposition reaction.
Ccarbonic acid → Carbon dioxide + water
H2CO3 → CO2 + H2O
Single-Replacement Reactions
2 K + 2 H20 → 2 KOH + H2
potasium + water → potassium hydroxide + hydrgen
A single displacement reaction, also known as a single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound. It can generally be represented as: {\displaystyle {\ce {A + BC -> AC + B}}}
Mg + Cu(NO3)2→ Mg(NO3)2+ Cu
magnesium + copper nitrate→ magnesium nitrate+ copper
Zn + 2 HCI → ZnCI2 + H2
zinc + hydrochloric acid → zinc chloride + hydrogen
double-replacement reactions
potasium bromide + silver nitrade → potassium nitrate + silver bromide
Na2SO4 + SrCI2→ 2 NaCI + SrSO4
KBr + AgNO3 → KNO3 + AgBr
sodium sulfate + strontium chloride → sodium chloride + strontium chlorite
A substitution reaction is a chemical process that leads to the formation of products with similar or identical binding properties by the exchange of bonds between two reacting chemical species. The general scheme in which this reaction is represented is as follows: {\displaystyle \mathrm {A{-}B\ +\ C{-}D\longrightarrow A{-}D\ +\ C{-}B} }
hydrochloric acid + sodium hydroxide → sodium chloride + water
HCI+ NaOH → NaCI + H2O
combustion reaction
carbon + oxigen →carbon dioxiede
C3H8 + 5 O2 → 3 CO2 + 4 H2O
C + O2 → CO2
CH3OH+ 3 O2 → 2 CO2 + 4 H2O
Combustion reactions are high-temperature exothermic redox reactions that take place between a fuel and an oxidant, resulting in an oxidized product. Heat is produced as a result of combustion. Combustion reactions are a chemical event for combustion to occur.
