A 0.588 gram sample of a metal, M, reacts completely with sulfuric acid according to: M(s) + H2SO4(aq) ----> MSO4(aq) +H2(g). A volume of 267 mL of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756.0 Torr and the temperature is 25 degrees C. Calculate the atomic mass of the 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..
