Equations

• half life:

  T(1/2) = 0.693/K
• energy:

  Q=mct
• Coffee cup calorimeter:

  1. total vol
  2. Q=mct
  3. find moles by dividing given by molar mass
  4. h = q/n
• Standard reduction potential:

  E cell = E cathode - E anode
• Element with excess element:

  h2 / h1 = n2 mol / n1 mol
• Number of moles with concentration:

  n = c x V
