Stoichiometry
,Content
●Define stoichiometry.
●Uses
●Mole concept
●Avogadro's number
●Problems
●Gas Lussacs
●Limiting reactant and problems
●Percentage yield and problems
, Q1. What is stoichiometry?
Ans: Stoichiometry tells you exact amounts of
chemicals (reactants) needed to make certain amounts
of products, with no waste. It's is quantitative relation
between reactants and products
It's based on the Law of Conservation of Mass.
Example:The reaction:
2H₂ + O₂ → 2H₂O
This reads as: 2 molecules of Hydrogen + 1 molecule of
Oxygen → 2 molecules of Water.**
The coefficients (2, 1, 2)are the mole ratio, which is the
heart of stoichiometry.
