Procedure: Melting point of RCO2H Before observing the melting point of the unknown sample‚ the melting apparatus had to be standardized with a standard substance having the melting point of 151°C-153°C. After placing a small sample of the standard in a capillary tube and inserting the tube into the sample tube holder‚ the plateau on the device was set to 15°C below the expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

Gravimetric Determination of Calcium ABSTRACT Determining the mass of a pure compound is a method of a gravimetric analysis. One of the gravimetric analyses is the precipitation; it is a method of separating the analyte from the unknown sample as a precipitate where it will be filtered and converted into a known composition that can be weighed to determine its mass (Skoog et al‚ 2013). Determining the mass of calcium by using gravimetric analysis was the objective of the experiment. A 25 mL

Critical Path Analysis INTRODUCTION: Planning‚ Scheduling and Controlling are three important functions of management. Planning involves the formulation of objectives and goals that are subsequently translated into Specific plans and projects. Scheduling is concerned about the implementation of activities necessary to achieve the laid down plans. The function of control is to institute a mechanism that can trigger a warning signal if actual performance is deviating (in terms

Backtracking: an implicit solution tree is built‚ but when it becomes apparent that the current path cannot lead to the desired solution‚ rather than return to the root node‚ the latest alteration is undone and an alternative is chosen. This means the computational work done in reaching the current point is not wasted. Perhaps a more significant saving is that in some cases this would mean that that search path could be abandoned before completion. Suduko: 1. TRAVELLING SALESMAN PROBLEM: 1

The Parable Story "Dead Men’s Path" In this short story "Dead Men’s Path‚" Chinua Achebe gives the protagonist an exciting chance to fulfill his dream. Michael Obi was fixed officially headmaster of Ndume Central School‚ which was backward in every sense. He had to turn the school into a progressive one‚ however the school received a bad report when the supervisor came to inspect. Why did the school get a nasty report and Obi could not become a glorious headmaster even though he put his whole

Word Count: 842 The goal of Buddhism is to reach Nirvana and extinguish one’s flame. [1]The Noble Eightfold Path is the method of reaching Nirvana‚ thereby ending suffering caused by Samsara‚ the world of rebirth. An average person that does not have the goal of cessation can still benefit by taking the Noble Eightfold Path. The eight items discussed in the Noble Path can be interpreted in a non-Buddhist context simply as a means to improve one’s wellbeing. An individual can become a better all

“ Dead Men’s Path” Over the years‚ populations around the world have been raised with many different cultures and beliefs. These are cultures that are accepted by some and denied and frowned upon by others because they have their own beliefs. Over the recent years the cultures do tend to change in the fact that they add new beliefs to the old ones. In Achebe’s “Dead Men’s Path” Michael Obi the newly appointed headmaster of the Ndume School has different religious and cultural beliefs then that

DEAD MAN’S PATH by CHINUA ACHEBE The title of this story "Dead Man’s Path" foreshadows the series of events about to take place in the story. "Dead Man’s Path" does not only refer to the ancestral pathway but also refers to Obi’s choice of action. His "path" by not compromising has made him a "Dead Man". Dead in this context is not death‚ but is referring to his failure. His dream died. The title also foreshadows dark events that would occur in the story. Meaning this story has quite a sad ending
