I've never actually studies physics at A-level or degree level, but I'm pretty sure this is an example of nuclear fusion. Physicists; please correct me if I'm wrong!
H2+Br2-->2HBr
The reaction of alkali metals with water release hydrogen.
The given reaction is an example of "synthesis" reaction, in particular one in which two elements react to form a chemical compound.
Synthetic elements are mostly produced by neutron capture. This is different from decay, fission, or fusion, but is more like fusion. In neutron capture, a free neutron is captured by the nucleus of an atom, producing a new isotope. The new isotope is likely to have too many neutrons, because it was a neutron that it captured. With too many neutrons, it wants to undergo decay by converting a neutron into a proton, and emitting a negative beta particle. This does not alter the mass number, but it does increase the number of protons in the atom by one, and so it increases the atomic number by one. For example, an atom of 237Np captures a neutron and becomes 238Np, which decays by negative beta decay to become 238Pu. Some synthetic elements are produced by fusion.
There are a few types of reactions. This type of reactions are called single displacement reactions. The reaction between water and magnesium is an example for this.
H2+Br2-->2HBr
For example the ammonia production; the magnetite catalyst is the most common.

They form compounds. For example, Na + Cl --> NaCl The compound formed depends on the elements in the reaction.

Not necessarily. It merely means that one or more of the products is a gas.
Nylon is one example of a synthetic (man-made) fibre.

For example, water reacts with zinc, releasing hydrogen, an element.
