What mass of hydrogen chloride gas is required to produce 250ml of a hydrochloric acid solution with a pH of 1.57?
Cocaine overdose and addiction are major public health problems. One novel treatment involves the administration of high activity mutants of human butyrylcholinesterase (BChE) (i.e. this would be a protein-based ‘drug') that would hydrolyze and d..
a 25.00-ml sample of orange drink with 2 g of ki and 25.00 ml of 0.0131 m kio3 added was back-titrated with a 0.0302 m
Explain what is the half-life of a compound if 50% of a given sample of the compound decomposes in 60 min. Assume 1st-order kinetics in ([A]/[A]o)=-kt=ln2/k
For a particular redox reaction Cr is oxidized to CrO42- and Fe3 is reduced to Fe2 . Complete and balance the equation for this reaction in basic solution. Phases are optional.
The addition of 6 g of salt to a sample of pure water causes its freezing point to be reduced from 0°C to -1.5°C. After an additional amount of salt is dissolved in the solution
Using the van der Waals equation, calculate the pressure of 14.0 g of N2 in a 0.600 L container at 27.0 °C. The van der Waals constants
Two different mixtures of gasahol are accessible the first containing 23% alcohol and the second 30% alcohol. Explain how many gallons of the second mixture must be added to 220 gallons of the first mixture to produce a mixture containing 27% alco..
Why can a first nitration be done at 0 degrees Celsius but the ice bath is removed to complete the reaction in a dinitration
Suppose we have a flask with a movable piston in which pressure is kept constant at 1.00atm. If an 8.00gram sample of solid ammonium nitrate is introduced into the flask what is the volume of the flask in liters at 298K when the ammonium nitrate h..
