Compute the radius of a cesium ion in CsCl if the density is 3.97g/cm3 as well as it is assumed that the ions touch through the body diagonal of the unit cell.
Consider the titration of 25.0 mL of 0.0500 M HClO4 (perchloric acid, a strong acid) with 0.100 M KOH (a strong base). (a) Find the volume require o reach the equivalence point (complete the reaction). Find the pH after adding the following volume..
What is the balanced chemical reactions that takes place when h2o2, concentrated h2so4, and Cu(s) is placed in solution. One of the byproducts should be copper sulfate (CuSO4) and there is some gas evolution during the reaction.
Photomultiplier tube with 9 dynodes and an applied voltage of -90V applied. explain how this set up can generate 10^7 electrons at the anode for each photon hitting the cathode.
A 275mL sample of O2 is collected over water at 60 degrees C the total pressure 755 torr what is the volume of O2 at STP?
what is the volumetric flow rate of steam leaving the turbine. If the turbine operates adiabatically, what is the work output
what is the vapor pressure at 40 degrees Celcius of a solution containing 4.60*10^2 g of glycerin, C3H8O3, nonvolatile, nonelectrolyte solute, in 4.5*10^2 g of water? The vapor pressure of water at 40 degrees Celcius is 55.3 mmHg
A particular metallic element, M, has a heat capacity of 0.36 J * g^-1 * K^-1. It forms an oxide that contains 2.90 g of M per gram of oxygen. (a) Using the law of Dulong and Petit (Cp x M = 25 J per mole per Kelvin), estimate the molar mass of th..
