H2O means two atoms of hydrogen combine with one atom of oxygen to make one molecule of water. The H stands for hydrogen and the subscript 2 of the H indicates that there are two atoms of hydrogen. The O is the symbol for an oxygen atom. This means that 2 hydrogen atoms and one oxygen atom bond, or join together, to form water
The chemical formula H2O is the formula of water.
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)
Hydrogen peroxide ... but its written as H2O2.
H2so4+2koh=k2so4+2h2o
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'
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
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
