- In a town (before 1950) where high amounts of PVC products were manufactured, many people in the town and surroundings, experience sickness due to the toxin agent vinyl chloride, a byproduct of polyvinyl chloride (commonly known as PVC) reaction. Hi, can you elaborate on the following: do you think modern day EPA and Federal regulations (if they were similarly in place in the early 1950’s) would have been effective in countering vinyl chloride toxicity problem before it started to affect individuals, or do you think that even with regulation in place this threat might have occurred the same way? Why? Justify your answer.TRUE OR FALSE __________ 6. The bowl of the funnel for gravity filtration may be filled to the brim. __________ 7. Transfer liquids and solutions from a reagent bottle or beaker with the aid of a stirring rod. __________ 8. Never touch, taste, or smell a chemical unless specifically told to do so. __________ 9. If uncertain as to how to dispose of a chemical, dumping it into the sink followed by copious amount of water is a safe disposal procedure. __________ 10.

- End-of-the-Pipe Control versus Pollution Prevention The marginal cost of reduction curve illustrated in Figure 4.5 assumes a particular approach to reducing pollution, often called end-of-the-pipe control. In other words, when we draw that upward-sloping MC curve, we assume that firms respond to regulation by maintaining the same basic production technology but adding on scrubbers or filters to clean up their emissions. Under these conditions, rising marginal costs of reduction are quite likely. However, suppose that firms radically overhaul their production technology, so that they completely eliminate emissions. This is known as a “pollution prevention” strategy. An example might be a jeweler, who in the face of regulation adopts a closed-loop production system. This is one in which all mineral waste products are recovered from recycled wastewater and then reused. What would the marginal cost of reduction diagram look like in this case? a. Specifically, assume that…A well is drilled through a hydrocarbon-bearing formation which is at its irreducible water saturation and it has a porosity of 28%. Rock core data indicates that (a=0.81, m=2, and n=2). The mud used for drilling is water-base, with a salt concentration (NaCl) of 50,000 ppm. The connate water has a salt concentration (NaCl) of 20,000 ppm. The shallow and deep resistivity logs readings are 12 ohm-m and 50 Ohm-m respectively. You should assume that the deep resistivity tool will be sensing the virgin zone, which does not experience any mud-filtrate invasion, and that the shallow resistivity tool will be sensing the flushed zone. The formation temperature is 145° F. What is the hydrocarbon saturation of the formation and what is the water saturation in the flushed zone?Ash was estimated in the sample of hay, and the records were as follows, note that the moisture is 18%. Weight of crucible = 14 g Weight of crucible + sample = 15.2 g Weight of crucible + ash = 14.1 g Calculate: i. Ash percentage according to the fresh material ii. Ash percentage according to the dry matter iii. Organic matter percentage according to the dry matter iv. Organic matter percentage according to the fresh material
