If an iron scoopula, instead of a plastic one, is used to add unknown metal to HCl solution, will it affect the calculated molar mass of the unknown metal?
Why are the products attached to C3 of 1,4 pentadiene more acidic than the methyl hydrogen atoms of propene? Maybe you can help me with this one. Are the C3 atoms more acidic because there is more s character involved with the atoms and as the s ch..
