After the extraction process, the organic solvent containing the organic compound was cooled and filtered after the crystals appeared. Upon filtration, the filter paper with the crystals are weighed immediately. Assume there were no additional steps in between and after, what are the possible errors committed in this set up?
Because of the risk of lead poisoning, the exposure of children to lead-based paint is a significant public health concern. Thefirst step in the quantitative analysis of lead in dried paint chips is to dissolve the sample. Corl evaluated several dissolution techniques.24 In this study, samples of paint were collected and pulverized with a Pyrex mortar and pestle. Replicate portions of the powdered paint were then taken foranalysis. Results for an unknown paint sample and for a standard reference material, in which dissolution wasaccomplished by a 4–6-h digestion with HNO3 on a hot plate, are shown in the following table. (a) Determine the overall variance, the variance due to the method, and the variance due to sampling. (b) What percentage of the overall variance is due to sampling? (c) How might the variance due to sampling be decreased?
Problem Solving (PLEASE READ THE PROBLEM THEN ANSWER THE QUESTION BELOW. I will rate you 5 stars just answer this pleaseee PROBLEM While the rest of the family was finishing up a game of volleyball in the bright afternoon sunshine. Brendon attempted to start a fire in the charcoal grill. He arranged the charcoal briquettes and squirted them with lighter fluid. He waited a few minutes for the fuel to soak into the charcoal and then he lit the pile of charcoal briquettes with a match. Flames from the match quickly begun to ignite the briquettes. Just as the fire got going. Brendon’s brother knocked the volleyball out of bounds and Brendon ran to get it. By the time he returned the ball and chatted with the family, the fire appeared to have gone out. Brendon grabbed the can of lighter fluid and squeezed it sides to douse the charcoal again. Suddenly, the can of lighter fluid exploded, spewing burning fluid everywhere. Luckily, Brendon dropped the can---not a fraction of a second too…

TRUE OR FALSE: Volatile drugs are best protected with waxed paper. Carbon dioxide is released as a result of acid-base reaction. Vegetable parchment is a transparent waterproof paper. In cascade impaction, the particles are passed by mechanical shaking through a series of sieves. Bulk powders are dispensed in individual doses. When making powders there is a manufacturing expense in individual wrapping of powder doses Powders packed are usually not potent Granules are intended for use with potent drugs because of inherent error Bulkiness decrease with increase in particle size Low angle of repose poorly flow and has high bulk density
