Let's break down each chemical equation and match them with the corresponding types of chemical reactions:
1. 2Na + Cl2 → 2NaCl
This equation represents a synthesis reaction, also known as a combination reaction. In a synthesis reaction, two or more substances combine to form a single product.
2. 2HgO → 2Hg + O2
This equation represents a decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances.
3. Zn + 2HCl → ZnCl2 + H2
This equation represents a single replacement or displacement reaction. In a single replacement reaction, one element replaces another element in a compound.
4. PbBr2 + Al2O3 → PbO + AlBr3
This equation represents a double replacement or displacement reaction. In a double replacement reaction, the positive and negative ions from two different compounds swap places.
5. C3H8 + O2 → CO2 + H2O
This equation represents a combustion reaction. In a combustion reaction, a substance reacts with oxygen, typically producing heat and often involving the release of light or flames.
