Compute the theoretical yield of aspirin to be obtained when 1.5 g of salicylic acid as well as 4.0 ml of acetic anhydride (density= 1.08 g/ml) are mixed together. Molar masses- acetic anhydride= 102.1 g/mol; salicylic acid = 138.1 g/mol.
A gas mixture containing oxygen, nitrogen, and neon exerts a total pressure of 1.20 atm. If helium added to the mixture increases the pressure to 1.50 atm, what is the partial pressure (atm) of the helium
Acid Rock Drainage is a common environmental process that releases toxic metals, such as cadmium (Cd2+), and lots of acidity (i.e. H+) into streams and rivers. One strategy to remediate acid mine drainage is to fill the streams with carbonate rock..
