Question

6 examples for chemical double displacement​

Answer 1

Answer:

Each reaction has reactants that react with each other to form compounds called products. In most cases, the reactants are compounds. Each of the reacting compound lends one molecule/compound for exchange with the molecule/compound offered by the other compound. Anions and cations of compounds change their placement to react and form altogether different compounds. This type of reaction is also called metasynthesis or double replacement.

EXAMPLES ARE GIVEN BELOW:

1. AgNO3 + NaCl ➜ NaNO3 + AgCl
2. Pb(NO3)2 (aq) + 2NaI (aq) ➜ PbI2 (s) + 2NaNO3 (aq)
3. BaCl2 (aq) + CuSO4 (aq) ➜ BaSO4 (s) + CuCl2 (aq)
4. Na2SO4 (aq) + 2BaCl (aq) ➜ Ba2SO4 (s) + 2Nacl (aq)
5. MgS (s) + 2HCI (aq) ➜ MgCl2 (s) + H2S (g)
6. NaOH (aq) + HCl (aq) ➜ NaCl (aq) + H2O (aq)
