Archaeological Anthropology Question 1: First Appearances of Religion When we think of religion, we often are reminded or churches or temples, morality, and an all-powerful, all-knowing, and benevolent being often referred to as a God, Goddess, or in some forms of recent religions, multitudes of the formers. As cited by the Oxford Dictionary there is one common definition of religion which is the “The belief in and worship of a superhuman controlling power, especially a personal God or gods.”…

Why is crime such a large part of our everyday society? Since the beginning of time, crime has been a large part of history, which gradually increased throughout the years, and continues today in everyday life. Crime is something that is caused by either force, impulse, fun, accident, or environmental factors. Some people have been raised since childhood in areas where crime rates were at a high and this may have compelled them to follow a negative figure, thus resulting in that person…

In the writings of Fyodor Dostoevsky’s “Notes from the underground” and LU XUN’S “Diary of a madman,” the idea of an unreliable narrator is deeply imbedded to make the reader deliberate twice of the situation at hand. In both writings, there are characters whose credibility has been seriously compromised. However, the characters in both writing differ in their levels of credibility and verge of insanity. Furthermore, both authors allude to the many social problems relevant in their society and…

Eighth grade students from Central Middle School rushed into Dorney Park merrily, with huge smiles on their faces on June 9th. The trip to Dorney Park in Allentown, PA has always been the field trip all eighth graders look forward to years in advance. Parsippany students have been going to Dorney Park for a field trip in eighth grade for the past sixteen years and it has always been wonderful. Thankfully, June 9th was a gorgeous day in spring, a perfect day to go to Dorney Park. The amusement…

coaster from across the park. The top speed of THE DOMINATOR is a 60 mile per hour spiral, that will have you scoring big. You will never know where the next turn will take you. The average speed of this exhilarating ride is 40 miles per hour! Some points will have you going at a constant speed, but you never know when it will speed up or slow down. Once you work your way up, don’t worry, because gravity will pull you back down… eventually! As you build up your momentum and reach the top of the…

gives a difference of 1.10-0.54=0.56 g and a percentage of (0.54/1.10)*100=49.09% The true melting point of pure benzoic acid is 122.41°C and I received 126.9°C as my melting point. This gives a difference of 126.9°C-122.41°C=4.49°C and a percentage of (122.41/126.9)*100=96.46% Results: Impure benzoic acid 1.10g True melting point of benzoic acid 122.41°C Pure benzoic acid 0.54g Acquired melting point of benzoic acid 126.9°C Discussion: Each part of this lab was very important. So…

in water when the temperature of the water reaches 100°C? A The particles stay close together. B The particles continue to glide past each other. C The particles move far apart. D The particles are destroyed. ____ 14. The melting point of water is 0°C. Its boiling point is 100°C. The thermometers show the temperature of four samples of water. Which statement is true? A Only sample B is solid. B All four samples are liquid. C Only samples A and C are liquid. D None of these ____ 15. Hailey…

The freezing point of the cyclohexanol was about 17.7°C, and the freezing point for the unknown solute mixed into the cyclohexanol was about 6.2°C. So the approximate change in temperature of the two freezing points was about 11.5°C. With this calculated information, the found molar mass of the unknown solute B was about 278.4g/mol, which is close to given molar mass of octadecanol. Conclusion- This lab allowed us to determine the molar mass of the unknown solute B by finding the difference in…

There a two insane loops that you must endure extreme centripetal force in order to make it through The Temple alive. The underground adventure is an unreal chance to witness what it is like underneath the surface, with the highest air pressure point on the ride! The speed will never disappoint, you will reach speeds up to 85 mph! The ride has to work against gravity as you travel through the jungle. Riders will feel velocity throughout the whole ride and will feel terminal velocity at the…

with higher boiling points will have longer retention times than chemicals with low boiling points. With that thought in mind and based on the data, it is clear to say that the major products that were produced with toluene, acetophenone, and nitric acid were indicated by peaks 4 and 5 on the toluene GC spectrum. These chemicals were o-nitrotoluene and p-nitrotoluene. This was determined by first finding the literature values of all the reactants’ and products’ boiling points. Each peak was then…
