Describe how to prepare 100 ml of 0.200 M acetate buffer, pH 5.00 starting with pure liquid acetic acid and solution contaning ~3 M HCl and ~3 M NaOH
Draw the skeletal structure of the product or mixture of products that result from the bromination of the given starting material with less than one equivalent of NBS in the presence of peroxides.
Calculate the energy change in kilojoules per mole when lithium atoms lose an electron to bromine atoms to form isolated Li+ and Br- ions. [The Ei for Li(g) is 520 kJ/mol; the Eea for Br(g) is -325 kJ/mol.]
Estimate the enthalpy change for the combustion of one mole of ethanol (C2H5OH) using average bond dissociation enthalpies (in KJ/mol) for C-?H: 413, O-?H: 463, C-?O: 358, C-?C: 154, C=O: 122, and O=O: 498
A 1.95 g sample of potassium bicarbonate is decomposed by heating. If the resulting potassium carbonate weighs 1.54 g and the calculated yield is 1.35 g, what is the percent yield
In the following experiment, the water in the glass is stirred by slowly lowering a weight (m=3kg) through a series of pulleys. If the 3kg weight is lowered 10m, the stirrer spins, but eventually all of the kinetic energy of the stirrer is turned ..
For the average person, a LDL chlesterol value is less than 200mg/dL. (200mg of LDL cholesterol per dL of blood) What is this value in g/mL
Calculate the maximum yield of substance X that could be obtained if 10g of X were recrystallized from 50 mL of the solvent at the above conditions.
Explain why lattice energy calculations based on the born mayer equation reproduce the experimentally determined values to within 1 percent for LiCl but only 10 percent for AgCl given that both compounds have the rock salt structure
The first ionization energy of lead (Pb) is 716 kJ/mol. If a Pb atom is ionized using a photon of ultraviolet radiation having an energy of 1.987E-18 J, what is the amount of leftover energy that goes into the kinetic energy of the ejected electro..
The rare earth metal terbium is produced from terbium (III) flouride and calcium metal by a single replacement reaction. Given 27.5 g of terbium (III) flouride and 6.96 g of calcium, what is the theoretical yield (in grams) of terbium
Gold can be hammered into extremely thin sheets called gold leaf. If a 197-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft multiplied by 1.0 ft, what is the average thickness of the sheet in meters
