To match the equations to the type of reaction, we need to understand the different types of chemical reactions and their characteristics.
1. Synthesis: In a synthesis reaction, two or more substances combine to form a single, more complex substance. It can be represented by the equation:
A + B → AB
2. Single replacement: In a single replacement reaction, one element replaces another element in a compound. It can be represented by the equation:
A + BC → AC + B
3. Combustion: In a combustion reaction, a substance reacts with oxygen to produce heat and light. It usually involves the burning of a fuel. It can be represented by the equation:
Fuel + Oxygen → Carbon Dioxide + Water
4. Double displacement: In a double displacement reaction, the positive ions of two compounds switch places, resulting in the formation of two new compounds. It can be represented by the equation:
AB + CD → AD + CB
5. Decomposition: In a decomposition reaction, a single compound breaks down into two or more simpler substances. It can be represented by the equation:
AB → A + B
Now let's match the equations to the type of reaction:
a. 2 NaCl + Br2 → 2 NaBr2 + Cl2
This equation is an example of a double displacement reaction (Column B, d).
b. MgBr2 + 2 NaCl → MgCl2 + 2 NaBr
This equation is an example of a double displacement reaction (Column B, d).
c. C3H8 + 5 O2 → 3 CO2 + 4 H2O
This equation is an example of a combustion reaction (Column B, c).
d. 2 H2O → 2 H2 + O2
This equation is an example of a decomposition reaction (Column B, e).
e. Na + Cl → NaCl
This equation is an example of a synthesis reaction (Column B, a).
So, the matches would be:
a. Double displacement
b. Double displacement
c. Combustion
d. Decomposition
e. Synthesis
