Well, darling, 2H2O is the chemical formula for water. It simply means there are two molecules of water present. So, next time you see 2H2O, just remember it's just a fancy way of saying "two water molecules." Stay hydrated, sweetie!
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
if you mean what the reaction is then... 2K + 2H2O --> H2 + 2KOH The products are hydrogen gas and potassium hydroxide.
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)

Trihydrate - basically 3 molecules of water (just as dihydrate is 2H2O) Unless you're referring to the molecule 3H2O used in measuring the total body water - in that case it's 'tritiated water'
H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
