Two of every three atoms that make up water is a hydrogen atom.
They could make Cyclobutadiene, cyclobutyne, methelynecyclopropene, tetrahedrane, vinylacetylene or butatriene. Or they could just be together as a bunch of carbon atoms and some hydrogen atoms. There is no reason to assume that they interact.
12 inches make an inch
It takes 2.5cm to make 1 inch.
This could vary from how much you set it up. A printer could go from 50dpi-800dpi. (dpi is dots per inch.) For type setters, 72 points equals one inch.
For the water molecule (H2O) two hydrogen atoms are needed.
It would take about 254 billion Carbon atoms lined up in a single row to span one inch.
We can make a hydrogen molecule by fusing 2 hydrogen atoms....!!
it is the hydrogen that burns to make gas hot
Hydrogen and helium make about 98% of the atoms in the solar system !
I'm not entirely sure if that question can really be answered, since it all depends on context. I would assume that a starch molecule would have the largest number of hydrogen atoms opposed to any other molecule, but if someone were to get picky, DNA would take it hands down.
Well methane has a chemical structure of CH4 (one carbon surrounded by 4 hydrogen atoms), so for 2 methane you would need a total of 2 carbon atoms and 8 hydrogen atoms (or 4 H2 molecules)
Hydrogen peroxide (H2O2) is made up of hydrogen and oxygen atoms. It consists of two hydrogen atoms and two oxygen atoms.
A molecule consists of many atoms. When you have a hydrogen molecule, or whatever other type of molecule for that matter, you have many hydrogen atoms that make it.
CH4 and 2 H2 Carbon can only make 4 bonds and hydrogen atoms are very reactive so they react to hydrogen gas.
To make a molecule unsaturated, a double bond would need to be removed. This results in the molecule having fewer hydrogen atoms bonded to the carbon atoms, allowing it to form additional bonds with other atoms or molecules.
12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.
