- Calculate the bulk density of a 110 cm3 soil sample that has a 25 percent water content (gravimetric or mass basis) and weighs 150 g.An amino acid moves randomly through water with steps of about 3 angstroms (3 x 10^-8 cm) in length at a rate of 1 x 10^10 steps per second. This substance is passing through a reverse phase HPLC column which has a plate height of 0.010 cm. 1. Estimate the diffusion coefficient for the amino acid in water. 2. Calculate the width at the base of the elution zone after the amino acid has migrated 50 cm through the columnChemistry Whats the definition of transfer and persistence in forensic science with historical and recentliterature references
- TRUE OR FALSE Powders that have low density and high porosity are free flowing. Surface roughness leads to poor flow characteristics. Micromeritics affects the maximum penetration of inhalation aerosols based on particle size. The greater the number of particles per dose, the lower the variability between dosage units. Bulk volume is the volume of spaces. Laser light scattering technique enables the use of surfactants to determine the primary particle size. The bioavailability of poorly soluble drugs influenced by state of subdivision of the drug. Spatulation is the technique of choice when blending small amounts of powders. Bulkiness decreases with increase in particle size Powders require disintegration before the onset of action. The more asymmetric a particle, the greater the surface area per unit volume Packing is the ratio of the void volume to the bulk volume.A supporting electrolyte is usually added to the analyte solution to minimize solution resistance.minimize solution conductivity.make the analyte less soluble in solution.increase the scan rate.Sketch a graph of the van Deemter equation (plate height versus flow rate). What would the curve look like if the multiple path term were 0? If longitudinal diffusion were 0? If the finite equilibration time were 0?
