Solid precipitate
An exchange reaction is defined as a chemical reaction in which two different molecules or pairs of molecules exchange places. So yes, a chemical exchange reaction will result in different molecules trading positions.
You will get a positive result for hydrogen because the reaction of zinc and hydrochloric acid produces zinc chloride and hydrogen. The chlorine atoms from the hydrochloric acid attach to the zinc, leaving the hydrogen behind and thus, you have hydrogen.

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.
The result is a net displacement vector.

You will get a positive result for hydrogen because the reaction of zinc and hydrochloric acid produces zinc chloride and hydrogen. The chlorine atoms from the hydrochloric acid attach to the zinc, leaving the hydrogen behind and thus, you have hydrogen.
You think probable to a precipitate, an insoluble compound.
The process you describe is known as precipitation, and the solid substance that was formed as a result of the reaction is called precipitate
The product is an insoluble compound.
