Think of water as HOH, which is basically a H+ ion and an OH- ion. So then, in solution, the reaction looks like this:
Na+ + OH- + H+ + Cl- ----> Na+ + Cl- + H+ + OH-
and then if we put the ions together, we get
NaOH + HCl ----> NaCl + H2O.
It's a double Replacement (:
Na2CO3 (aq) + CaCl2 (aq) -----> 2 NaCl(aq) + CaCO3(s) This is a double displacement reaction.
salt metathesis or double decompositionPlease see the link.
double displacement reaction is when the positive ion of one compound replaces the other, to form two new compounds. Single displacement reaction is when one element replaces another in a compound
This reaction is called a "single displacement" reaction, as the sodium replaces the potassium in combination with the chlorine. *This is the high-temperature distillation reaction to produce metallic potassium, and is not a spontaneous reaction because potassium is more reactive than sodium. The corresponding single replacement reaction is K + NaCl => Na + KCl.

For example a single displacement reaction is:2 Na + 2 HCl = 2 NaCl + H2

No. Not every double displacement reaction is a precipitation reaction. If we look at just one reaction, a neutralization reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH), we'll see this: HCl + NaOH => NaCl + H2O The end products are sodium chloride (NaCl, or table salt) and water (H2O). The salt is soluble in water so it will not precipitate out. There are many, many double displacement reactions, and the ones that will result in a precipitate will be ones where an end product is not soluble.
Yes. It's a double replacement reaction.
Na2O + H2O ---> 2NaOH this is a metal oxide (base) reacting with water to form an alkali
