• If I am to write the quantum numbers for the highest energy electron in Cr, or any of the transition elements in its respective row, would n=3, l=2?
  
• Would any of the first row transition elements have a specific valence electron quantity, or is that something that varies for each one?
  
• How do you calculate the mole ratio for two compounds to predict a base amount to neutralize an acid?
  
• How do you turn KMnO4 (aq) + H2C2O4 (aq) into a molecular equation, then break it down through decomposition?
  
• Is 2H2O2(aq)=2H2O(l) + O2 (g), only decomposition, or also combustion?
