2Na + 2H_2O -> 2NaOH +H_2 You have to count the number of atoms in both sides of the reaction to be equal, to make it a little easier you can make a list.it's correct too but remember that Na2O in H2O will react in an acid-base-reaction due to the O(2-)-ions Na2O + H2O --> 2 NaOH.2Na+ 2H2O=2NaOH + H2. dont fiddle about much with the oxygens becuase thats the last element you balance and as you can see i didnt have to do anyhing to oxygen it has just Na+2H20->Na(OH)2+H2 Na(OH)2 is the normal way to represent Sodium Hydroxide H2,Cl2 ,etc are diatomic elements.
Chemical Forums: Na + H2O reaction
Sodium oxide will also react with water to produce sodium hydroxide though. Unlike most other metallic oxides though, sodium oxide is ionic, meaning when it dissolves in water, there are Na+ ions and O(2-) ions. An O(2-) ion will remove a proton from a water molecule, thereby creating two hydroxide ions.In this video we'll balance the equation Na + H2O = NaOH + H2 and provide the correct coefficients for each compound.To balance Na + H2O = NaOH + H2 you'll...
