In hho gas, how do I split the two to form h2 and O?

Question

I want to create h2 by splitting hho gas into h2 and o.

I know it has been done.

can you help me?

Answer 1

I'm guessing mean HHO, H₂, and O.  It is important to put things in the proper formatting for Chem so that when you get some complicated chemical formulas you can still solve problems.  If you are just trying to balance the equation you need to observe the law of definite proportions.  In HHO there are two hydrogens to every one oxygen (are you trying to represent water vapor? H₂O (g) ).   Oxygen is diatomic so you actually want H₂ and O₂.  Now set up your unbalanced equation: H₂O --> H₂ + O₂.  

 

To balance the equation you will need to make the number of H and O on the left equal the the number of H and O on the right (mass cannot be created or destroyed).  Since there are 2 O on the right you will need 2 H₂O on the left.  

2 H₂O --> H₂ + O₂

Now you check and find you have 4 H:2 O on the left and 2H:2O on the right.  You need more H on the right so you increase the coefficient accordingly.   

2 H₂O --> 2 H₂ + O₂

If your teacher requires you to specify phase you will need to include that information: 2 H₂O (g) --> 2 H₂ (g) + 2 O₂ (g)

This reaction can be achieved by electrolysis among other methods.
