Chemistry
Differentiate between the following :
Decomposition reaction & a double decomposition reaction
Answer
| Decomposition reaction | Double decomposition reaction |
|---|---|
| A chemical reaction in which a compound decomposes to give two new elements / a new compound & an element / two new compounds is called a Decomposition reaction. | A chemical reaction in which both reactants [compounds] are decomposed to give two new compounds by exchanging their radicals is called a Double decomposition reaction. It is represented as XY + AB ⟶ XB + AY |
| For example: 2HgO ⟶ 2Hg + O2 | For example: CaCl2 + Na2CO3 ⟶ 2NaCl + CaCO3 ↓ |
