i need help with stoichemtry Li3N+3H2O-->NH3+3LiOH

Question

how do you do stoichiometry

Answer 1

The equation that you have there is already balanced! So you don't need to do anything beyond that for the balancing. Where that will come in handy then in a stoichiometry context then is that it tells you what the mole ratio should be between substances.

For example, in your equation

Li₃N + 3 H₂O --> NH₃ + 3 LiOH

meaning that the mole ratio between H2O and NH3 would be

3 moles of H2O for 1 mole of NH3, based on the coefficients

Answer 2

Kaitlyn,

 

Li₃N + 3H₂O → NH₃ + 3LiOH

 

I don't understand.   This is already as balanced as it can be.  You don't have to do anything more to it.
