The mass of a cube of iron is 439 g. Iron has a density of 7.87 g/cm3. What is the mass of a cube of lead that has the same dimensions?
Use the van der Waals parameters for chlorine to calculate approximate values of (a) the Boyle temperature of chlorine and (b) the radius of a Cl2 molecule regarded as a sphere.
Give the chemical equation for the reaction that occurs in (B) to reach equilibrium.
A bottle containing 350 g of cleaning solution is used for carpets. If the cleaning solution has a specific gravity of 0.850, what volume of solution was used?
How did I get a greater than 100% recovery of benzoic acid?, To quickly summarize, the lab dealt with isolating benzoic acid from a mixture via chemically active extraction.

Write down a lewis structure for SbCl5 and also explain Does the the octet rule is obeyed by this molecule Explain how many grams would 3.01 * x10 23 atoms of tellurium have?
For each solution, determine the number of moles of HAn and of An- ion at equilibrium. For each solution, caluate the HAn and An- ion molar equilibrium concentrations. Determine the reciprocal of the An- ion concentration for each solution.
The solubility of CO2 in water at 25°C and 1 atm is 0.034 mol/L. What is its solubility under atmospheric conditions? (The partial pressure of CO2 in air is 0.0003 atm.) Assume that CO2 obeys Henry's law.
The reaction CH3CH2NO2 + OH- → H2O + CH3CHNO2- obeys the rate law d[A]/dt = -k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25°C.
The value of Kf for cyclohexane is 20.0°C/m, and its normal freezing point is 6.6°C. A mass of 1.604 g of a waxy solid dissolved in 10.000 g of cyclohexane results in a freezing point of 4.4°C. Calculate the molar mass of the solid.
