At 25.0°C, a sample of Xe gas occupies 531 mL in a piston-cylider apparatus when the external pressure is 337 torr. At what pressure (torr) will its volume become 625 mL if the temperature does not change?
The synthesis of zinc iodide was performed using 1.7748g of zinc and 1.1185g of iodine. Determine the limiting reactant and calculate the theoretical yield of zinc iodide in grams
transferred from an oven (183°C) to 189 g of water at 23.2°C, into which it is immersed. The water and steel together reach a temperature of 27.9°C. What is the mass of the steel in grams
The distribution coefficient, k = (conc. in hexanes/ conc. in water), between hexanes and water for solute A is 7.5 . What weight of A would be removed from a solution of 10g of A in 100mL of water by a single extraction.
Determine which of them exhibit resonance. (In other words, which of the following molecules exhibit resonance? Note: there is more than one answer and you must choose all of the molecules in the list that exhibit resonance.)
What is the velocity of a first-order reaction when the reactant concentration is 6 x 10-2 M and the rate constant is 8 x 103 sec-1?
calculate the amount of sodium nitrate in mg in one liter if 3.8mg of nitrate was detected in one liter of water.
One can approximate boiling point at reduced pressure using a pressure-temperature nomograph. What would you expect the observed boiling point to be at 50 torr for a liquid that has a boiling point of 280 degrees celsius at 760 torr
Suppose you are measuring the mass of a sample using a balance that employs a standard mass of density dw = 8.0 g/mL. a) What is the buoyancy correction (m/m\'), if the sample density is less than 8.0 g/mL?
if the the atmospheric pressure is 685 mm Hg, what would the partial pressure of oxygen and of nitrogen be?
Choose the answer in which the two atoms are listed in order of increasing ionization energy
Consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. Each pair includes a maternal and a paternal member (e.g., A^m and A^p.).
Cesium(Cs) is used extensively in television cameras and in photocells because it has lowest ionization energy of all the stable elements.Determine the maximum kinetic energy of a photo electron ejected from cesium.
