The only intermolecular forces in methane are London dispersion forces.The major intermolecular forces would be dipole-dipole forces and London dispersion forces. But The electronegativities of C and H are so close that C-H bonds are nonpolar. There are no bond dipoles and no dipole-dipole interactions.Even if the molecule had polar C-H bonds, the symmetry of molecule would cause the bond dipoles to cancel.So the only forces left to consider are London dispersion forces. .

I need help writing a python 3 function. I need to write a function that takes 3 inputs which are lists (first names, middle ini., and last names ). It needs to take those names and put them together correctly and then print them in a column, 1 on top of another, and so on. they need to be printed in aphabetical order of the last names. Also, they need to have a border around the whole column and the initials need to be aligned vertically. if there is no initial, a space can just take its place to keep things aligned. I feel like being able to look at the code and go over it line by line until I understand it and can recreate it myself is the best way I learn. If someone could create this function for me, that would be unbelievably helpful. Thanks SO much for the help and sorry for any grammar issues, I\'m writing this from my phone Solution def createNames(firstName, middleName, lastName): #creating a function to generate names from the given lists and give output of names in a list allNames=[] for i in range(len(firstName)): name=lastName[i]+\" \"+middleName[i]+\" \"+firstName[i] allNames.append(name) allNames.sort() Â Â #sorting the names in alphabatical order of lastNames return allNames firstNames=[] Â Â #give here firstNames middleNames=[]Â Â #give here middleNames lastNames=[]Â Â #give here lastNames namesList = createNames(firstNames, middleNames, lastNames) print(\"_______________________________\ \") for name in namesList: print(name+\"\ \")Â Â #printing the names one by one print(\"_______________________________\") .

I need help with my geotechnical engineering HW,, Can a soil have a low void ratio and a low total unit weight at the same time? Explain. Name and define three types of weathering. From memory, try to write the equations for water content, void ratio, dry unit weight, moist (total) unit weight, and saturated unit weight. After 5 minutes you can look up the definitions, and write the correct answers below your attempt. For a given soil, the following parameters are known: e -0.62, specific gravity 2.65, moisture content w=15% Determine: 3. 4. 5. 6. dry unit weight moist unit weight water content at S-100% saturated unit weight . Solution 3. No, low void ratio and low total unit weight at the same time are possible, beacause if void ratio is low ultimately the mass of the solids is high so that the unit weight increases. 4.Types of Weathering: i) Mechanical weathering: which produces clasts of rock/mineral which are smaller that the original and of the same general composition. There are two basic processes: Fracturing and Abrasion ii) Chemical weathering: It also produces smaller pieces, but of a different chemical composition, the minerals have been changed in an attempt to be more in balance with surface conditions. iii) Biological weathering: It is the action of plants and animals can and do lead to both mechanical and biological weathering. 5. Water Content = Weight of water/weight of solids Void ratio = volume of voids/volume of solids Moist unit weight = mass of soil * accleration due to gravity / volume of soil Dry unit weight = mass of solid * accleration due to gravity / volume of soil or moist unit wieght/(1+water content) Saturated unit weight = submerged unit wiegt + unit weight of water 6. Dry unit Weight = 16.35 KN/cubic meter Moist unit Weight = 18.81 KN/cubic meter Water content at S=100%, w=23.39% Saturated Unit Weight = 20.185 KN/cubic meter .

12. Your friend has high protein and sugar in her urine. She repeats the tests and determines that these components are repeatable, suggesting they are present in her urine. What does this signify to you, as her friend and primary care physician? Solution Everyone has protein in their blood. The main protein in your blood is called albumin. healthy kidneys should only filter tiny (trace) amounts into the urine as most protein molecules are too large for the filters (glomeruli). When she have protein in her urine, it is called proteinuria (or albuminuria), which is usually a sign of chronic kidney disease. As proteinuria progresses, oedema may occur. High levels of glucose in her urine may indicate hyperglycemia, or high blood sugar, which often indicates the onset of diabetes. Untreated hyperglycemia can lead to ketoacidosis, which can result in diabetic coma and even death. Possible causes of proteinuria: 1. Diseases of the glomeruli like glomerulonephritis or diabetes. 2. Urine infection such as cystitis/urinary tract infections. 3. Congestive heart failure, a first warning of eclampsia in pregnancy. 4. May be she tested concentrated urine samples (early morning), or if she have become dehydrated or havenâ€™t drunk much. It is also better to check protein/creatinine ratio (PCR test). 5. Temporary proteinuria may occur after vigorous exercise or if she have a high fever. Hope this helped you! Thank You So Much! Please Rate this answer as you wish.(\"Thumbs Up\") .

11. What are the components of the user interface? Solution Now a days there are lots of types of user interfaces. We are going to describe the components in general, using four main categories: Containers: This are panes, windows, forms which hold other components. Containers have grids in order to arrange other components. There are rows and columns grids, flexible grids, flow grids. Containers also has the responsibility to adapt to the screen size. Some containers are: Window Frame Form Dialog Menus: This user interface components allows the user to navigate through the different commands of a given applications. Menus organize commands in a logical and hierarchical manner, using several submenus. Some types of menu are: Main Manu (located on the top of the container). Menu Bar Contextual Menu Controls. This components allows communication between the user and the application. This allows the user to send and receive request, messages and information from/to the application. This the category which hold the bigger number of components. Some of them are the following: Text Boxes Text Area Buttons File Control Select List Check Optinon Label Tables Graphic Area Media Controllers: The controller is not a graphic component but it is necessary to process input/output. This are pieces of code which capture user interaction, takes arguments and details and finally process commands and requests. Normally the controller uses the publisher/subscriber pattern. It subscribes itself with the components and receive notifications when the events occur, being able to react accordingly. .

It is the anion from the second ionization of HySO4, for which Ka2 1.2 x 102 The with water to produce AlroH), (whichi actually only sightly soluble), thus increasi 42 1.2x 10. The aluminum ion us increasing [H\']. Solution For question no 146 When we dissolve Al 2 ( SO 4 ) 3 we get Al +3 and SO 4 -2 ion. Now aluminum ion reacts with water and does the polarisation of water now it seems like any cation can do that but No since aluminum ion has sufficient value of charge density, therefore, it interacts with water( Al +3 + 3H 2 O = Al(OH) 3 + 3H + ) to form Alumnimum hydroxide and releases hydronium ion or H + ion which makes water acidic. So from this, we can say that if any cation has more charge density it will on hydrolysis make water more acidic. For question no 131 Acidic nature of HX(where X can be any halogen) is determined by Polarity difference between hydrogen and halide will try to generate positive and negative end which can only possible if bond dissociates as the one which takes the electron away will have the negative charge (usual halide ) while hydrogen will have the positive charge. Now acidic nature of hydrogen halide is also determined by how easily any hydrogen halide give the H + ion in water since release of hydrogen ion is directly related to bond dissociation energy of hydrogen and halide so strength of H-X decide the strength of acid since bond dissociation energy of HI is weak so it is strongest amongst all. So it depends upon two factors so D option is correct. .

14. The pnt difference between the bronchi and bronchioles is that Bronchioles have type I and type II squamous (thin, flat, pavement) epithelial cells, whereas cilia. a. the bronchi have columnar epithelium with b. The bronchiolar glands are situated directly beneath the lining epithelium (submucosa), whereas the glands of the bronchi are larger and external to the cartilage rings or plates The smooth muscie of the bronchi is arranged \" whereas the smooth muscle of the bronchioles longitudinally (along the axis of the airway) is arranged circularly or spirally around the The bronchi are not directly attached to the lumen of the airwe d? connective tissue fibers of the lung tissue, whereas the bronchioles are directly embedded into the lung connective tissue structure. Solution Despite its probable importance in health and disease, the elastic tissue in the trachea has rarely been investigated. In addition, various aspects of the trachealis muscle are controversial. The aim of this study was to clarify this clinically relevant anatomy. Ten cadaveric tracheobronchial specimens (age range 68â€“101 years; seven males; no major airway pathology) were qualitatively investigated by microdissection. Serial histologic sections from multiple sites in three specimens were analyzed after staining for elastin. Findings were correlated with observations from video tracheobronchoscopies. An extensive and prominent meshwork of elastic tissue was found within the trachea and bronchi. Elastic fibers were predominantly longitudinal and aggregated into discrete bundles within the membranous wall of the trachea and main bronchi; a discrete fibroelastic membrane bridging the membranous wall of the trachea; and vertical laminae connecting the ends of successive cartilages. The longitudinal elastic bundles continued into the segmental bronchi, becoming thinner and more circumferentially distributed. .
