Consider 4.90L of a gas at 365 mmHg and 20. ° C . If the container is compressed to 3.00L and the temperature is increased to 40. ° C , what is the new pressure, P 2 , inside the container? Assume no change in the amount of gas inside the cylinder. Express the pressure numerically in millimeters of mercury.
Determine the concentrations of BaBr2, Ba2 , and Br- in a solution prepared by dissolving 1.62 × 10-4 g BaBr2 in 1.50 L of water.
Compound A, C6H10O2, is optically active. It dissolves slowly in aqueous NaOH, consuming one equivalent of base. When the solution is acidified, A is slowly regenerated.
Brass is a copper and zinc alloy containing 31.8% zinc by mass and having a density of 8.73 {\rm \frac{g}{cm^3}}. A fitting composed of common brass has a total volume of 335.6 {\rm cm^3}
Calculate the pre-equilibrium concentration of Fe3+(aq) in a solution made by mixing 2.8 mL of 2.010?3 M Fe(NO3)3 and 7.2 mL of 2.010?3 M NaSCN. Assume the final volume is 10.0 mL.
a mixture of co co2 and o2 is contained within a 275 ml flask at 0c. if the total pressure is 780 torr the co has a
calculate the molarity of acetic acid in a vinegar sample knowing that 5.00 ml of vinegar requires 43.50 ml of 0.105 m
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..
