For many divorced and separated parents with children there will be a common answer as to why they ended up with the child custody and visitation arrangement they have. The answer being‚ "the judge decided it." In other words‚ the judge chose the parenting arrangement you have based on his/her belief of what was in your child’s best interest.

Theoretical Framework Tinto’s Theory of Departure. Tinto (1975) introduced the concept of retention where it says that “students who socially integrate into campus community increase commitment to the institution and are more likely to graduate. This theory focuses on how students’ lack ofinteraction within the higher education community leads to student departure.. Based on Van Gennep’s (1960) anthropological model of cultural rites and passages‚ “students must separate from former groups‚‚ undergo

Experiment 3: Separation of the Components of a Mixture General Chemistry 101 (CHEM 101)‚ ISP SCUHS Report 2 September 15‚ 2013 Abstract Mixtures are made up of substances or components. If the mixture is fairly uniform in composition‚ properties‚ and its overall appearance‚ it is homogenous. If the component parts are clearly separated‚ it is heterogeneous. In order to identify the components in a mixture‚ methods must be used to sort out the components. However‚ the same methods will not

Introduction: Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach

Introducton : The most common macromolecules found in living organisms are carbohydrates ‚ lipids‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain tests to determine the presence of

Aspirin analysis Introduction Aspirin‚ which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the

Acid Base And Salt Acid Acids:- The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour‚ such as curd‚ tamarind‚ lemon‚ etc. Types of Acids:- Acids are divided into two types on the basis of their occurrence – Natural acids and Mineral acids. Natural Acid:- Acids which are obtained from natural sources are called natural
