A chemical equation, like all equations, contains an equals sign ( = ). It shows a chemical reaction, where something turns into something else. You probably mean the chemical symbol that would represent hydrogen. The symbol for an atom of hydrogen is H. In hydrogen gas the atoms usually pair up into hydrogen molecules for which the symbol is H2. If the gas is very hot the molecules dis-associate, so then the symbol will be just H, or sometimes (H) to make it clear that monatomic hydrogen is referred to. If you want an equation : H2 + heat = 2 (H)
Hydrogen gas is produced by two Hydrogen atoms bonding to gain an octet, due to how it is diatomic. The formula for hydrogen gas is H2. The other diatomic elements are carbon, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
there is none, it is a noble gas and therefore does not form an ion
2H+(aq) + 2e- = H2(g)
2H+ + 2e- --------> H2
it is H2.
Sodium Stearate + Ca2+ and Mg2+ = Calcium Stearate + Na+ Ions (Soap) (Dissolved in water) (Soluble in water)
CaCl2 + H2O = CaO + 2HCl
because it is dependent upon the way of combination of atoms in isomorphs.for example NaNO3 and KNO3 have same atomic ratios. Because both Na and K belong 1 grup and give only one electron for bond formation.
H2so3--------------------------------2h+ + (so3)2-
None.H-O-O-HA rough molecular representation of hydrogen peroxide showing all single covalent bonds. No ionic bonding here.
The dipole in the nitrogen-hydrogen bond points towards the nitrogen end. The arrow showing a dipole moment points towards the more electron rich region, with its tail at the electron poor region.
The molecular formula for Methane is CH4 It's 1 atom carbon, 2 hydrogen molecules (Hydrogen molecules come in H2 gases) so the formula would be C + 2(H2) = CH4
Sodium Stearate + Ca2+ and Mg2+ = Calcium Stearate + Na+ Ions (Soap) (Dissolved in water) (Soluble in water)
