उत्तर
Synthesis and substitution reaction:
- Synthesis reaction: “Is a chemical reaction in which two or more elements or an element and a compound or two compounds combine to form a new compound.”
\[\ce{2Al + 3Cl2->2AlCl3}\] - Substitution reaction: “Is a chemical reaction takes place when an element or radical (more reactive) replaces another element in a compound.”
\[\ce{A + BC->B + AC}\]
\[\ce{Mg + CuSO4->Cu + MgSO4}\]
