How many grams of h2o will be formed when 32.0 g h2 is mixed with 32.0 g o2 and allowed to react to form water?

*Given
  Mass of hydrogen ()  -  32.0 grams
  Mass of oxygen ()     -  32.0 grams

*Additional Information 
  Molar mass of hydrogen () - 2.00 g/mol
  Molar mass of oxygen ()    - 32.00 g/mol
  Molar mass of water ()    - 18.00 g/mol
 
Chemical Reaction:
                    
   +     -------->
                                  
*Solution

From the chemical reaction above, we can see that for every 1 molecule or mole of oxygen (), we would need 2 molecules or moles of hydrogen () to form water (). 

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
