A racquetball court is 20 ft wide. If we consider only motion along this direction and treat the ball as a particle in a box, if the ball weighs 1.4 ounces, what quantum number corresponds to a racquetball hit 100 km per hour and what speed would ..
The reaction of magnesium metal with HCl yields hydrogen gas and magnesium chloride. What is the volume, in liters, of the gas formed at 736 torr and 18 oC from 4.49 g of Mg in excess HCl?
Sulfamic acid (FM 97.094) is a primary standard that can be used to standardize NaOH. What is the molarity of a sodium hydroxide solution if 38.92 mL react with 0.3341 g of sulfamic acid
The recovered CuSO4•5H2O was then heated for 20 minutes at 120°C. The mass of the new hydrate was 2.17g. (The molar mass of H2O = 18.015 g/mol, and the molar mass of CuSO4= 159.61g/mol) Calculate the mass of CuSO4 in the new hydrate (CuSO4•XH2O).
