If a sample of recently prepared 1-bromobutane is washed successively with water, cold concentrated sulfuric acid, and then very dilute (5%) aqueous sodium bicarbonate solution, tell which layer is 1-bromobutane in each of the 3 washings. Solution For each of the washing, there will be a different distribution of layer. Now layer distribution is dependent on the density of the liquid. Because we know that, density = mass/volume, thus for a similar volume, one having more density has a higher mass and the higher mass refers to the bottom position in a container due to gravitational force (W = mg). Now the densities of these liquids are: 1) 1-bromobutane = 1.2676 g.mL 2) Concentrated sulfuric acid = 1.84 g/mL 3) 5% aqs. sodium bicarbonate = 2.20 g/mL 4) water = 1 g/mL. Now in water-1-bromobutane, the upper layer is water and the bottom layer is 1-bromobutane, in sulfuric acid-1-bromobutane, the bottom layer is sulfuric acid and the upper layer is 1-bromobutane, and in sodium bicarbonate-1-bromobutane, the bottom layer is sodium bicarbonate and the upper is 1-bromobutane. I hope it helps!!!!!!!!! .

If the Android platform you are developing for does not support fragments, how would you go about providing fragment-like processing in you Android Application ? Hints: Would you have multiply activities? Which UI elements (controls/widgets) would you use? Solution A Fragment represents a behavior or a portion of user interface in an Activity.. One big reason to stick with the SupportFragment for a while is that you do not have access to the ChildFragmentManager until API17. Instead of creating fragments we can use by custom views for mutliple display. Letâ€™s implementation of fragments in views. First, weâ€™ll have the notion of a Container, which can show an item and also handle back presses. The activity assumes thereâ€™s always a container and merely delegates the work to it. The list is also quite trivial. Now, the meat of the work: loading different XML layouts based on resource qualifiers. Using custom views works great, but we would like to isolate business logic into dedicated controllers. we call those parameters. This makes the code much more readable and facilitates testing. MyDetailView could look something like this Make your fragments shells of themselves. Pull view code up into custom view classes, and push business logic down into a presenter that knows how to interact with the custom views. Then, your fragment is nearly empty, just inflating custom views that connect themselves with presenters: At that point you can eliminate the fragment .

E 4. Elijah Samuels and Tony Winslow agreed to form a partnership. Samuels contributed $200,000 in cash, and Winslow contributed assets with a fair market value of $400,000. The partnership, in its initial year, reported net income of $120,000. Calculate the distribution of the first year\'s income to the partners under each of the following conditions: 1. Samuels and Winslow failed to include stated ratios in the partnership agreement. 2. Samuels and Winslow agreed to share income and losses in a 3:2 ratio. 3. Samuels and Winslow agreed to share income and losses in the ratio of their original investments. 4. Samuels and Winslow agreed to share income and losses by allowing 10 percent interest on original investments and sharing any remainder equally. Solution 1. When there is no stated ratio then profit distributed equally Share of Samuels = 120000x1/2= 60000 Share of winslow= 120000x1/2 = 60000 2. Share of Samuels=Â Â 120000x 3/5 = 72000 Share of winslow= 120000x2/5 = 48000 3. Value of investments= Samuels (200000) + Winslow (400000)= 600000 Share of samuels = 120000x200000/600000 = 40000 Share of winslow = 120000x 400000/600000= 80000 4. Income after interest on investments = 120000- 600000x10%= 60000 Share of samuels = 60000x1/2 = 30000 Share of winslow = 60000x1/2 =30000 .

During a total lunar eclipse, in which the moon passes entirely into the shadow of the earth as cast by the sun, the moon is not completely dark, but is often a deep red in color. The shade of red varies widely from one total eclipse to the other. Why? 1. During the sunset, the Sun transfers some red light to the moon. 2. The earth acts like a giant water drop because of its oceans, and the moon winds up 3. None of the worldâ€™s sacred holy books discuss this situation, so it must be forever a total mystery. 4. Low frequencies pass more easily through the long grazing path through the Earthâ€™s atmosphere to be refracted finally onto the moon. 5. High frequencies pass more easily through the long grazing path through the Earthâ€™s atmosphere to be refracted finally onto the moon. Solution 4) Some light from the sun passes through Earth\'s atmosphere and is bent toward the moon. Low frequencies (red is having low frequency and highest wavelength) pass more easily through the long grazing path through the Earthâ€™s atmosphere to be refracted finally onto the moon. .

Driving School has 4 learning centres. The network of each learning centre is a LAN of its own. Network Cheap is contracted to install network connections between the learning centres. Network Cheap proposed to use RIP version 2. As the CEO of Driving School, will you accept this proposal? If you do not accept the proposal, what would you use for the routing protocol? Give your reasons. Solution IGRPâ€”Interior Gateway Routing Protocol , EIGRPâ€”Enhanced Interior Gateway Routing Protocol or OSPF V2â€”Open Shortest Path First came to a mind but RIP V2â€”Routing Information Protocol is a good choice The characteristics of RIPv2 follow: Distance-vector protocol. Uses UDP port 520. Classless protocol (support for CIDR). Supports VLSMs. Metric is router hop count. Maximum hop count is 15; infinite (unreachable) routes have a metric of 16. Periodic route updates sent every 30 seconds to multicast address 224.0.0.9. 25 routes per RIP message (24 if you use authentication). Supports authentication. Implements split horizon with poison reverse. Implements triggered updates. Subnet mask included in route entry. Administrative distance for RIPv2 is 120. Used in small, flat networks or at the edge of larger networks. IGRP Converges slowly infact slower than RIP and for IGRP , OSPF or EIGRP all routers must be from Cisco Systems ( big constraint) .

Doris Washington recently assumed her new position as HR Director at the XYZ Company, a software development firm with approximately 350 employees. Her staff includes a seasoned generalist as well as a benefits clerk. During her first 90 days on the job, Doris has noted the following issues that seem to be embedded in XYZ\'s culture: 1) managers create their own interview questions; 2) for some employees, their compensation is simply determined by managers, not based on training, experience, geographic region, and so on; and, 3) the company seems to draw new employees from only two sources, one is the university from which the President of the company graduated.

DQ #4 Explain the US Government Thrift Savings Plans. Solution The US Government Thrift Savings Plans is a defined-contribution plan designed to give federal employees the same retirement savings related benefits which will be equal to that of workers in the private sector enjoy with 401(k) plans. Contributions to these plans are automatically deducted from each paycheck of federal employees. The thrift savings plan offers six different funds (government security fund, fixed-income fund, common stock fund, small cap stock fund, international stock fund and a life cycle fund) in which federal employees can invest. Because the thrift savings plan is based on tax-deferred contributions, any contributions made into it will not be taxed until the money is withdrawn, which can be deferred until retirement. Other Benefits of these US Government Thrift Savings Plans includes 1) agency matching contributions 2) agency automatic contributions 3) catch up contributions and 4) low expense ratios. .
