<u>Racemic </u><u>mixture</u>
An equimolar mixture of the enantiomers is called Racemic mixture. It may be represented as dl or (±)
Emitted/given off. exo is a way to remember that is is going away. think of a flame. the heat is emitted off onto you.
Ah is gold and Rh is rhodium and Os is osmium and Ir iridium
Reaction Rate is the rate at which a substance undergoes a chemical change.
Volume fraction = volume of the element / volume of the alloy
Volume = density * mass
Base: 100 grams of alloy
mass of tin = 15 grams
mass of lead = 85 grams
volume = mass / density
Volume of tin = 15g / 7.29 g/cm^3 = 2.06 cm^3
Volume of lead = 85 g / 11.27 g/cm^3 = 7.54 cm^3
Volume fraction of tin = 2.06 cm^3 / (2.06 cm^3 + 7.54 cm^3) = 0.215
Volume fraction of lead = 7.54 cm^3 / (2.06 cm^3 + 7.54 cm^3) = 0.785
As you can verify the sum of the two volume fractions equals 1: 0.215 + 0.785 = 1.000
