Answer: double replacement reaction
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example: [tex]Li_2O+CO_2\rightarrow Li_2CO_3[/tex]
2. Double displacement reaction is one in which exchange of ions take place. Neutralization is a special type of double displacement where acid reacts with base to form salt and water.
Example: [tex]KOH(aq)+HCl(aq)\rightarrow KCl(aq)+H_2O(l)[/tex]
3. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example: [tex]Zn+2HCl\rightarrow ZnCl_2+H_2[/tex]
4. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example: [tex]Li_2CO_3\rightarrow Li_2O+CO_2[/tex]
