Nitrogen from the air
Hydrogen from methane (natural gas)
Hope this helps :)

Sulfur dioxide is created by the combustion of sulfur, sulfurous fuels (bunker oils, coal), the smelting of sulfide containing ores (pyrites) and hydrogen sulfide (usually as a waste/safety process). Sulfer can also be emitted from diesel engines as a sulfate solid. Nitrogen oxides (NOx) result from any combustion process where air and fuel are burned at the correct temperatures, the use of nitic acid in plan processes, fertilizer manufacturng and from lightning heating the air. As an aside the sulfur in acid precipitation is in the form of H2SO3. In the same way the NOx compounds form assorted nitrogen acids.
It comes from the process of planetary differentiation. light elements such as nitrogen rise up to form the atmosphere,whereas heavy elements such as iron sink to the mantle.
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
N+O = No2
it is made with the haber-butch process
the Haber process is endothermic. Energy to make the reaction take place must come from something.
Historically, it was derived from bat guano but now it's primarily created by oxidizing ammonia made by the Haber process.
This is a fusion process, the nuclear reaction that powers our Sun. Hydrogen and hydrogen isotopes come together to make helium
Nylon can be composed of several different chemicals, but the most common elements are carbon, hydrogen, nitrogen and oxygen.
It would help to know what nitrogen gas you're talking about. The nitrogen in Earth's atmosphere mostly came from the oxidation of ammonia, which came from the fact that nitrogen is fairly common in the universe and that hydrogen is the most common element in the universe.

-gen is Greek for "make" Hydrogen means "water maker" as water forms when it is burned. Oxygen essentially means "acid maker" acid as it was once falsely believed that all acids contained oxygen. Nitrogen essentially means "saltpeter maker" as nitrogen is a component of saltpeter, a.k.a potassium nitrate.
Glucose is a product of the process of photosynthesis. The compounds used for this process is CO2 and H2O. So H comes from water.
oxygen, hydrogen, carbon, nitrogen and calcium come to mind.Bonus fact! Calcium is the most common metal in the human body.
I am not sure entirely what you mean but there are lots of elements that go around in pairs, e.g hydrogen, oxygen, nitrogen amongst others.
nitrogen come from the ground when it gets in the roots
