Chemical Reactions & Stoichiometry

Sept 13, 2021

molecule - a group of same atoms bonded together
compound - a group of different atoms bonded together

Chemical Reactions

chemical reactions are often described with an equation of the format below

  • reactants → products
  • 2H2 + O2 → 2H2O

chemical reactions can be either:

  • reversible - where products can easily become its original reactant form
  • irreversible - where products requires lots of energy to become its original reactant form

Stoichiometry

involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data
