I don't know what you consider "expensive". Hydrogen is the most common element in the universe, and can be readily produced by a variety of methods; at a couple of bucks per kilogram, it's one of the cheapest elements (and one of the very few that any schlub can make at home with stuff you probably have lying about the house).
you can get hydrogen when you make a metal react with acids or water such as when potassium or sodium is made to react with water it burns with a lilac colored flame and gives of hydrogen. but the reaction is very explosive and violent. If u use calcium instead of it .This wont be a vigorous reaction but the calcium is expensive. You can get hydrogen from zinc easily if you make it react with dil.HCl or dil.H2So4(sulphuric acid)
What you smell that is so awful is hydrogen sulfide.
Carbon can make 4 bonds with hydrogen. Nitrogen can make 3 bonds with hydrogen. Oxygen can make 2 bonds with hydrogen.
hydrogen and oxygen are the two elements which make up water
Yes, hydrogen gas is lighter than air and can make balloons float. However, hydrogen is highly flammable and can be dangerous, so it is not commonly used today. Helium is a safer alternative for making balloons float.
For no reason at all. It is just an expensive brand. Some of the extremely expensive Parker pens are expensive for the material they use to make them. For instance, an expensive might be gold-plated to make it worth more.
Collapsed Anti-Matter is expensive because it is impossible to make with current technology.
Evening dresses are so expensive because they are usually expensive to make, and as the best dresses are usually made by the best fashion experts for example Prada.
CH4 and 2 H2 Carbon can only make 4 bonds and hydrogen atoms are very reactive so they react to hydrogen gas.

This kind of equipment is so expensive because the government still supports the fossil fuels.
Not because hydrogen is more expensive and there are better electric charging point networks than hydrogen worldwide.
It is hydrogen.
We can make a hydrogen molecule by fusing 2 hydrogen atoms....!!

Because the companies that make them like money
One reason why Breitling watches are so expensive is because they use the latest technology which makes it very complex. Another reason is because they use expensive materials to make the watches.
