What element has the same physical and chemical properties as magnesium and strontium but a lower atomic mass?
Assume it took the entire allotted time. If we used anisole instead of methyl benzoate to run an analogous reaction, how much time would a similar nitration reaction take.
The nitrogen in a 4-tablet sample that weighed a total of 7.50 g was converted to ammonia by Kjeldahl digestion, followed by distillation into 100.0 mL of 0.1750 M HCl. The analysis was completed by titrating the excess acid with 11.37 mL of 0.108..
