El Greco’s Assumption of the Virgin is a masterful and imposing piece of art‚ spanning almost 7 feet in width and standing over 13 feet tall. The work was commissioned by the church of the Cistercian convent of Santo Domingo in Toledo to be the central panel of the church’s high altar‚ thus it should be imagined in its original form not as a single piece but one flanked by other religious artwork and alters including paintings of individual saints and the trinity. The painting depicts the Virgin

knowledge to create a novel that will awake the Nationalism of every Filipino for them to have courage to fight for their rights and for their country. The two novels he made showed the entire country under Spanish regime. Both Noli Me Tangere and El Filibusterismo the writings of Jose Rizal shows the poor condition of the Filipinos. We experienced discrimination‚ torture‚ violence‚ unequal rights‚ high taxes and corruption under the government of friars. The main reason why he wrote his novel is

Forbidden Lives The movie El Norte is a sad story about a brother and a sister -- Rosa and Enrique from Guatemala and their struggle of getting out of ethnically and politically repressed Guatemala and trying to fit into American society and fulfilling their dream the American Dream. On the other hand‚ this movie is a great depiction of the struggle faced by many people from Central and South America who are trying to get inside the United States. The main reason for Enrique and Rosa coming

beginning of 2015 the homicide rate in El Salvador has reached it’s highest point in history since the end of their 12-year civil war. This peak in homicides is due to gang leaders being moved to maximum security prisons instead of being in low security prisons. It also has to deal with the clash between street gangs and security forces. El Salvador has a population of 6.4 million people‚ from January to August there were 4‚246 homicides. Since this act of violence El Salvador has been ranked one of the

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities‚ audition and vision‚ which were combined with two levels of warning signal status. The two levels of warning signal status were signal

High School Students’ Conceptions about Energy in Chemical Reactions (focusing only in exothermic and endothermic reactions). Aim The aim of this study is to investigate students’ understanding of the energy concept in chemical reactions particularly in endothermic-exothermic reactions. Both qualitative and quantitative methodology was used for this investigation. A twenty-item multiple choice test was developed about the topic to measure the students’ understandings. This concept test was
