5 different types of chemical reactions
Text z Príbehu
- Ex:
- Synthesis of two elements: C + O2 --> CO2
- A + B --> AB
- two or more substances react to produce a single new substance
- Synthesis
- Synthesis of two compounds:2CaO + 2H2O --> 2Ca(OH)2
- Synthesis of a compound and an element:2CO + O2 --> 2CO2
- General Form AB --> A + BElements CO --> C + OCompounds Ca(OH)2 --> CaO + H2O
-
- One Reactant breaks down into two or more products.
- Decomposition
- Combustion
- Ex: A + BX --> B + AXCation ReplacementZn + CuCl2 --> ZnCl2 + CuAnion ReplacementBr2 + 2Kl --> 2KBr + I2
- A single element replaces a second element in a compound
- Single Displacement
- AB + CD --> AD + CBA and C are Cations (Positive Ions)B and D are anions ( Negative Ions)
- AgNO3 + NaCl --> AgCl + NaNO3
- Double Displacement
- In a double replacement or double displacement reaction. The Cations and anions of two compounds switch places.
- Ex: CH4(g) + 2O2(g) --> CO2(g) + 2H2O(g)
- A Combustion is a chemical reaction between Hydrogen, Oxygen, Carbon dioxide, Water, and Heat
