CH6:Stoichiometry-Calculation involving Reaction

-Stoichio: element
 Metry: measurement


-It's the study of calculating the amount of reactant used in a chemical reaction and how many product produced by the reaction
-----------------------------------------------------------------------------------
4NH3+5O2---->6H2O+4NO
4:5:6:4--the mole ratio
-Balanced chemical equation are required


*Coefficient in balanced equation tell us the number of moles reacted or produced and also be  used a conversion factors


-N2+3H2---->2NH3
N2:H2---1:3
NH3:H2---2:3
-------------------------------------------------------------------------------
Example:
CH4+2O2---CO2+2H2O


-0.15molCH4 x 1molCO2  =0.15molCO2
                           1molCH4
