Kyle Paulk SI CHEM 1201 An anesthesiologist is responsible for keeping track of how much anesthetic enters a person… as well as how much is needed. How might an anesthesiologist do his bookkeeping…Stoichiometry! Balancing Chemical Equations When a reaction occurs, bonds break and new bonds form, and the number of atoms of each element can actually be accounted for! How do we balance reactions? By inspection (trial and error) Make sure all formulas are correct! You must have the same number of atoms of each type on both sides of the equation Total Mass of the reactants = Total Mass of the Products CO(g) + O 2 (g) CO 2 (g) C 3 H 8 (g) + O 2 (g) CO 2 (g) + H 2 O(l) HCl(g) + H 2 O(l) H 3 O + (aq) + Cl - The Mole There are 6.022 X 10 23 atoms/ molecules, etc. in 1 mole of a substance. This number is known as Avogadro’s # 1 mol of sodium contains 6.022 X 10 23 atoms of Na 1 mol of carbon dioxide contains 6.022 X 10 23 molecules of CO 2 How many atoms of of Ar are there in 0.345 mole of Ar?
