  6. ok its like 3am and im feeling stupid. my book says group 3 has lower ionization energy than group 2 since group 3 electronic configurations are in the p block and the p have higher energy than the s orbitals but if they need high ionization energy if the p orbital is higher in energy, and therefore requires more energy to remove wtf im so confused. help
  7. I don't get how to do question b) - If the mole ratio is the same then why do you need to work out everything? omfg i dont get it. how do you even work this out.
