2H2
H2O. Haha its water! Di=2 Hydrogen Mon(o)=1 Oxide=Oxygen 2 Hydrogens; 1 Oxygen.
Hydrogen is a chemical element with the symbol H and atomic number 1.
It is 1/2.
2 Hydrogens and 1 oxygen.
An alkane with 20 carbons will have 42 hydrogens. This can be calculated using the formula 2n+2, where n is the number of carbons (C) in the alkane. So for an alkane with 20 carbons, the number of hydrogens would be 2(20) + 2 = 42.
Following the formula CxH2x-2 where X is the number of carbons in the desired Alkyne, you should get C8H14 (i think.....)
Ethanol has 2 carbons, one oxygen, and 6 hydrogens.
H2O, water.
2 hydrogens 1 oxygen
Four. A terminal carbon in an alkane is bonded to 3 hydrogens and 1 carbon, while a middle carbon is bonded to 2 hydrogens and 2 carbons.
H2O that's 2 hydrogens for every oxygen.
Well there is water and heavy water where the hydrogens are deuterium
