Calculate the Z for the fourth ionization of Ti when it requires 425.6 kJ of energy to ionize 0.185 moles of Ti^3+ to Ti^4+ ( The electron being removed is in the outermost valence orbital of Ti^3+ ground state, therefore n = 3)
Can someone please help me with this problem. I'm not sure what to do with the moles that we are given or if we even need them.
Which of the following statements are true regarding the liquid-liquid extraction performed in the synthesis of phenacetin. Note that there may be more than one correct answer. Dichloromethane is the bottom layer because it is more dense than water..
A 10 mL sample of a solution of Pb(ClO3)2 was diluted with water to 21 mL. A 10 mL sample of the dilute solution was found to contain 0.021 moles of Pb2+. What was the concentration of Pb(ClO3)2 in the original undiluted solution?
