A certain elixir is 92 proof. A proof is twice the volume percentage of alcohol in a blend. Ethanol's structural formula is CH3CH2OH with a molar mass of 46 grams/mole. The density is .79 g/ml. How many liters of elixir must one have in order to have 50 moles of carbon?
Metals ions can also be placed in a spectrochemical series. In this case, larger effective nuclear charges generally lead to larger values for (delta) . Based on this principle, predict a spectrochemical series for the following ions:
