An unit cell of CsCl was given. Chlorides are at the corners of a primitive cube with a cesium in the middle. Using the Cs atom as the origin calculate the first three terms of the Madelung constant for a CsCl crystal. Recall that M is cal calculated in terms of the ionic "bond distance" dCs-Cl.
Arrange the following ionic compounds in order of decreasing amount of energy released in lattice formation:
Gas stoichiometry and Percentage of calcium carbonate in the sample
How many atoms of manganese (atomic mass 54.94 g/mol) ar contained in 6.16 attograms
0.80g of hydrogen chloride is dissolved in water to make 2.5L of solution. What is the pH of the resulting hydrochloric acid solution?
What are the boiling point and freezing point of a 2.47 m solution of naphthalene in benzene? (The boiling point and freezing point of benzene are 80.1°C and 5.5°C, respectively.
Explain why bubbles are observed to emerge from the jar when it is in the boiling water. b. Explain why the lid "pops down" on the jar top soon after removing the jar from the boiling water.
The reactant concentration in a zero-order reaction was 9.00×10-2M after 175 s and 4.00×10-2M after 325 s. What is the rate constant for this reaction?
An odorous gas emitted by a hot spring was found to diffuse 2.92 times slower than helium. What is the molar mass of the emitted gas.
Find the mass of sodium required to produce 5.68 L of hydrogen gas at STP from the reaction described by the following equation: 2 Na + 2 H2O ® 2 NaOH + H2
Calculating concentration of an ion, Given the concentration of hydroxide ions, use the ion product constant of water to calculate the concentration of the other ion at 298 K
Calculate the catalytic efficiency of lysozyme (in units of M-1 s-1), in terms of the rate of encounter of enzyme with substrate. How does this value compare to the diffusion-limited value of k1 = 109 M-1 s-1?
pH = log[H3O+] , pH + pOH = 14, [H3O+] * [OH-] = 1.0 X 10^-14, pH = -log(0.001) = 3 Could you show me a few of the steps between line one and two in both of these conclusions?
