Noble gases are very unreactive, so you're not going to see them anywhere that reactivity is important. In fact, one of the main places they're used is in environments where reactions need to be stopped - to replace air in a reaction environment, for example.
To make steel, batteries, and Xerox machines, you wouldn't want something unreactive. Fluorescent light bulbs ("neon bulbs"), on the other hand, fit the bill nicely.
It should be at beginning. A hypothesis is called an educated guess of what might happen in the experiment.

Yes if a molecule with a COOH group is called a carboxylic acid.

Explanation:
Aluminium hydroxide (
) is a base and hydrobromic acid (HBr) is a strong acid.
Hence an acid-base reaction occurs between
and HBr
Balanced molecular equation:
![Al(OH)_{3}(s)+3HBr(aq.)\rightarrow AlBr_{3}(aq.)+3H_{2}O(l)](https://tex.z-dn.net/?f=Al%28OH%29_%7B3%7D%28s%29%2B3HBr%28aq.%29%5Crightarrow%20AlBr_%7B3%7D%28aq.%29%2B3H_%7B2%7DO%28l%29)
Balanced total ionic equation:

Balanced net ionic equation:
![Al(OH)_{3}(s)+3H^{+}(aq.)\rightarrow Al^{3+}(aq.)+3H_{2}O(l)](https://tex.z-dn.net/?f=Al%28OH%29_%7B3%7D%28s%29%2B3H%5E%7B%2B%7D%28aq.%29%5Crightarrow%20Al%5E%7B3%2B%7D%28aq.%29%2B3H_%7B2%7DO%28l%29)
(net ionic equation is written by removing common ions present in both side of total ionic equation)
The number of atoms in a molecule varies depending on the specific molecule formed. As a rule of thumb, a molecule must be composed of at least two atoms with no maximum amount of atoms as long as all the atoms in the molecule are bonded together somehow.
