Hydrogen burns with a "squeaky pop" when lit.
It smells like rotten eggs.
Hydrogen is highly inflammable. So it is used as a fuel. Also because hydrogen is colourless and odorless, it is hard to identify leaks.

The electron in a hydrogen atom is most likely to be found in the 1s orbital.
To find the number of moles of hydrogen in 3.5 moles of (NH4)2CO3, first identify the stoichiometry of the compound. In (NH4)2CO3, there are two moles of hydrogen per mole of compound. Therefore, in 3.5 moles of (NH4)2CO3, there would be 2 * 3.5 = 7 moles of hydrogen.
The number of hydrogen bond acceptors in a compound refers to the atoms that can accept hydrogen bonds. These typically include oxygen, nitrogen, and sometimes sulfur atoms. To determine the exact number of hydrogen bond acceptors in a compound, you would need to identify these specific atoms within the molecular structure.
To identify lactose intolerance in children and adults, the hydrogen breath test is used to measure the amount of hydrogen in the breath.
Hydrogen cylinders are typically painted in a light sky blue color to help easily identify them in industrial settings.
Nonpolar compounds, such as hydrocarbons like methane or nonpolar solvents like hexane, do not participate in hydrogen bonding.
You can identify hydrogen and carbon dioxide by lighting a wooden splint and putting it near the gasses. Since hydrogen is flammable, the flame will get bigger. Since carbon dioxide does not burn, it may get smaller or go out.

Hydrogen is identified with a 'H' symbol and if dissolved in water it have a negative charge
