CaCl2 is not a reaction, but a compound. It can react with certain substances such as Mg.
The single replacement reaction for calcium and hydrochloric acid is: Ca + 2HCl -> CaCl2 + H2
Na2CO3 (aq) + CaCl2 (aq) -----> 2 NaCl(aq) + CaCO3(s) This is a double displacement reaction.
When hydrochloric acid reacts with calcium chloride, it forms calcium chloride and hydrogen gas. The chemical equation for this reaction is: 2HCl + CaCl2 -> CaCl2 + H2. This reaction is a double displacement reaction.
Condensation Reaction.
This is called a replacement reaction. When one element replaces another in a compound, it is called single replacement or single displacement. An example isZn + 2HCl ---> ZnCl2 + H2 where the zinc replaces the hydrogen in the acid to form zinc chloride.
This is a single displacement reaction where fluorine displaces chlorine in calcium chloride to form calcium fluoride and chlorine gas.
Single displacement reaction and a double displacement reaction are redox reactions. apex- false
Precipitate because you're making a solid out of two liquids.
This is a single displacement reaction.

In a single displacement reaction two products are obtained.

No, single displacement and double displacement reactions are not always redox reactions. Redox reactions involve electron transfer between reactants, while single displacement and double displacement reactions do not always involve the transfer of electrons.
