{:(H(2)O rarr2H^(+) + 1//2 O(2)+2e^(-)),(1 mol " "2 mol):} (Here, oxidation number of oxygen changes from -2 in H(2)O to 0 in O(2). Therefore, 2 moles of electrons are lost during the oxidation of 1 mol of water.) The
formula H2O indicating each molecule contains two atoms of hydrogen and one atom of oxygen. The number of moles for each substance is written before the formula with values of one mole not written. Two moles of water is written as 2 H2O and 1.8 moles of water is written as 1.8 moles ...
