Hydrogen peroxide ... but its written as H2O2.
H2so4+2koh=k2so4+2h2o
Two water molecules (2H2O) have four oxygen atoms in total.
2H2O represents two molecules of water, which is in liquid phase at room temperature and pressure.
H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
2nacl+2h2o
The chemical formula for calcium sulfate dihydrate is CaSO4 · 2H2O. It can also be written as CaSO4 · 2H2O.
Crystallised BaCl2·2H2O will be de-hydrated when heated, loozing 2H2O per mol BaCl2·2H2O
Water can be broken down to oxygen and hydrogen and hydrogen can be ignited in oxygen to form water. 2H2O --> 2H2 + O2 (takes energy) 2H2 + O2 --> 2H2O (releases energy)
