H2 or hydrogen gas is neither a mixture nor a compound. It is an element because it is only made up of one element which is hydrogen.
The compound is water - H2O; the molecule of hydrogen is H2.
The reaction is:Ca + H2O = Ca(OH)2 + H2
it depends on what is reacting most commonly it is H2 gas or O2 gas or CO2 gas
- To obtain the useful components from a mixture.- To remove the unwanted components from a mixture. - To separate 2 or more useful components from a mixture.
It becomes the diatomic gas H2. Hydrogen gas.

The total moles of gas in the mixture is 0.220 + 0.350 + 0.640 = 1.210 moles. To find the pressure of H2, we need to consider the mole fraction of H2, which is 0.350/1.210 = 0.289. So, the pressure of H2 is 0.289 * 2.95 Atm = 0.852 Atm.
when H2 is bought near burning splinker it burns with pop sound
Air is a mixture of gases. It contains Nitrogen (N)-78%, Oxygen (O2)-21%, Argon(Ar)-0.93% And a mixture of other trace gases including: Hydrogen (H2): 0.000055%, Carbon dioxide (CO2)- 0.03 % and Hydrogen (H2): 0.000055%
H2 or hydrogen gas is neither a mixture nor a compound. It is an element because it is only made up of one element which is hydrogen.
When the components of a mixture are uniformly intermingled, it is a homogeneous mixture.
you get NaCl, H2, and a great deal of energy
The compound is water - H2O; the molecule of hydrogen is H2.
The reaction is:Ca + H2O = Ca(OH)2 + H2
Little Johnny is no more, What he thought was H2O Was H2 SO4.
it grabs electrons from hydrogen and forms H2 which ignites to explode'
