-Works with quantative analysis of chemical reactions and is about measuring the amounts of elements & compounds involved in a reaction. This is part of the study of reactions.
1 AgNO3 + 1 KCl ‑‑‑‑> 1 AgCl + 1 KNO3
In stiochiometry, this balanced equation can also show the mole ratio of 1:1:1:1
* Note that the equations all must be balance. Otherwise, the mole ratio will be totally wrong.
-The coefficient is of the balanced equations is equaled to the number of moles reacted or produced.
-What you need over what you have
eg. 4NH3 + 5O2 ------> 6H2O + 4NO
# of moles of H2O = ? ---------------> 2.00 moles O2 (6 mol H2O/5 mol O2) = 2.40 moles of H2O
