Using complete sentences, briefly answer the following: A) Accurately describe the procedural steps for partitioning 2-propanol from 70% rubbing alcohol. B) What is the name and the advantage of this technique? C) Briefly explain how it works? Solution A) Isopropyl alcohol or 2-propanol is miscible in water but is immiscible in salt solutions.It forms distinct layer when salt like sodium chloride is added to its mixture with water (70 % 2-propanol+30% water) and separates from the aqueous layer. B) This technique is called salting out. C) Using this technique,liquids can be separated from their azeotropic mixtures using separating funnel.2-propanol dissolves in water by forming hydrogen bonds (partially miscible in water forming azeotrope).Salt being polar dissolves in polar aqueous medium but not in non-polar organic medium of 2-propanol.Thus, hydrogen bonds between 2-propanol and water is broken,rather salt ions form stronger polar electrostatic bonds with water molecules.The two liquids thus ,separates forming two distinct layers. The liquids forming two distinct layers ,one organic(2-propanol) and one aqueous layer can be seprated by draining out the liquid forming lower layer (less dense liquid 2-propanol). .

Using the method of 1/2 reactions balance the skeleton equation: I2 + H2S ---> I- + S Solution Ans. Balancing redox reactions under neutral condition: Step 1: Separate the half-reactions. Balance all the elements except O and H in each half-reaction individually. Oxidation half reaction: H 2 S -----------> S Reduction half reaction: I 2 --------------> 2 I ? Step 2: Balance O and H to both the half reactions- Oxidation half reaction: H 2 S -----------> S + 2 H + Reduction half reaction: I 2 --------------> 2 I ? ; [Not needed] Step 3: Add the two half-reactions to get balanced reaction. Cancel the terms common on opposite side of the reaction (if any) - H 2 S -----------> S + 2 H + I 2 --------------> 2 I ? ---------------------------------- H 2 S + I2 ----------> S + 2 H + + 2 I - # H + and I - form HI. So, the overall reactions turn to be- H 2 S + I 2 ----------> S + 2 HI .

Using the descriptions of the attributes given in the ERD below, provided the one partial dependency (3 points) and the one transitive dependency (2 points) (5 points total). Hint: Both dependencies are contained within the PRESENTATION table. Solution Transitive dependency: If there are three attributes in table and A->B but not B->A and B->C then A->C is known as transitive dependency In the given table of Presentation, Pres_SessionNum and Pres_Order are functionally dependent on Pres_AuthorID and this is functionally dependent on Pres_FName , hence Pres_SessionNum is transitive dependent on Pres_FName Partial dependency: If part of the primary key is used to identify an attribute then it is known as Partial dependency Pres_Room is functionally dependent on Pres_SessionNum and Pres_Order and Pres_SessionNum can solely used for identification of Pres_Room hence Pres_Room and Pres_SessionNum are partial dependent .

using the concepts of bonding and polarity explaining the importance of reactions . Solution Types of bonding 1. Ionic bonding : by sharing of two opposite charge eg.NaCl 2. Covalent bonding: by sharing of valence electrons eg. C-C 3.metalic bonding: it\'s a force of attraction between metal and electrons. bonding in metals like Cu, Al, Ag Polarity concept in bonding is molecules contain polar atoms just like in Water Water has one O and two H atoms and it forms polar bonding +Ve charge on H atom while -ve charge on O atom The concept of bonding and polarity in reaction In reaction if bonds are polar it will get break easily if it\'s non polar it\'s hard to break it\'s required high temperature or vigorous condition to Carry forward reactions. Most of the time in reaction covalent bonding is useed In that single bond is singma bonds are stronger than double bond i.e. pi bonds. Pi bonds breaker easily than the sigma bond. .

Using the competing values framework as a point of reference, how would you describe Verizon\'s current organizational culture? Provide examples to support your conclusions. Solution According to Schein (1992), [3] culture is the most difficult organizational attribute to change, outlasting organizational products, services, founders and leadership and all other physical attributes of the organization. His organizational model illuminates culture from the standpoint of the observer, described by three cognitive levels of organizational culture. At the first and most cursory level of Schein\'s model is organizational attributes that can be seen, felt and heard by the uninitiated observer - collectively known as artifacts . Included are the facilities, offices, furnishings, visible awards and recognition, the way that its members dress, how each person visibly interacts with each other and with organizational outsiders, and even company slogans, mission statements and other operational creeds. Artifacts comprise the physical components of the organization that relay cultural meaning. Daniel Denison (1990) describes artifacts as the tangible aspects of culture shared by members of an organization. Verbal, behavioral and physical artifacts are the surface manifestations of organizational culture. Rituals, the collective interpersonal behavior and values as demonstrated by that behavior, constitute the fabric of an organization\'s culture The contents of myths, stories, and sagas reveal the history of an organization and influence how people understand what their organization values and believes. Language, stories, and myths are examples of verbal artifacts and are represented in rituals and ceremonies. Technology and art exhibited by members or an organization are examples of physical artifacts. The next level deals with the professed culture of an organization\'s members - the values . Shared values are individuals .

Using Haskell, I need: -- | Produce a list where sequences of repeated elements in the given list are replaced by just one of the repeated element. Where the result of the following compress statement >>> compress [1,1,1,2,3,3,3,1,2,2,2,2] results in: -- [1,2,3,1,2] Solution Look the simple logic which we can apply to this problem is to find the repeating element in the list unitl we didnt get the next distinct element Once we get that element we stop comparing and stroes the index of that distinct element and will add the repeating element (the element on which we wereworking beforing getting the element) to the new compressed list For example list [1,1,1,1,2,2,3,3] we wnt to compress the list start with first element ie 1 and keep itrerating until we get 2 once we traversed to this element we stop traversing stores the index of element 2 now we will add 1 in compressed list and will do the same with rest of the elements in the list now next repeating element search will starts from the index whih we saves by getting the dinsctint element .

Use your own words to explain how the Black Death (1) , commodity prices (2) , and wage rates (3) combined to lead the Medieval Economy into a crisis. You can also use graphs to explain the interaction between those three determinants. Solution The decline of feudalism occurred due to a number of events which occurred during the Medieval era of the Middle Ages. Feudalism was based on the division of land by the king to nobles and vassals in return for their military service under the Feudal Levy. Land was the main source of the economy and was dependent on the peasants who worked on the land. Reasons for the Decline of Feudalism The reasons for the decline of Feudalism during the Medieval period of the Middle Ages included: The Decline of Feudalism - the Standing Armies The decline of feudalism came when rich nobles were allowed to pay for soldiers rather than to fight themselves. Life changed and Mercenaries were hired from all over Europe. The Mercenaries had few allegiances, except to money, and these paid fighting men were feared throughout Europe. The threat of the Mercenaries led on to the employment of professional, trained soldiers - the Standing Armies and ultimately the end of Middle Ages feudalism in England. Decline of Feudalism - the end of Feudalism in England Under feudalism the King was answerable to the Pope. At the end of the Middle Ages King Henry VIII clashed with the Pope and England subsequently broke with the Catholic church of Rome and the power of the Pope. This led to the establishment of the Church of England and the Dissolution of the Monasteries. It was the final \'nail in the coffin\' of the Medieval Feudal System, feudalism, in England. .
