The Amistad With any movie there is always a purpose and objective. The viewing process of the movie is to support literacy and to asses personal strengths and inspire personal growth. With the movie The Amistad the objective of the movie was to remind individuals of the progress that has been made since the slavery times of the past. It helps to remind people that there is much more change still to be made when it comes to situations that directly deal with the issue of race. Intentionally or not

Maria Ramirez Period 7 Word count 602 The Amistad The Amistad was a significant historical event that eventually led to important outcomes like the awareness of slavery and the encouragement of public opinion. The Amistad was a Spanish slave ship used in the 1800’s. On June 27‚ 1839‚ The Amistad left the port of Havana‚ Cuba with Captain Ransom Ferrer and two passengers‚ Jose Ruiz and Pedro Montez. Along with fifty-three African American slaves from the Mende tribe in Sierra Leone‚ “Ruiz had forty-nine

what up woOn June 28‚ 1839‚ the Spanish slave schooner Amistad set sail from Havana on a routine delivery of human cargo. On a moonless night‚ after four days at sea‚ the captive Africans rose up‚ killed the captain‚ and seized control of the ship. They attempted to sail to a safe port‚ but were captured by the U.S. Navy and thrown into jail in Connecticut. Their legal battle for freedom eventually made its way to the Supreme Court‚ where their cause was argued by former president John Quincy Adams

African slaves took charge of the crew to return to their homes‚ but they were discovered by American troops‚ who taken them as prisoners leading them to United States to determine what they would do with them. Upon arrival the slaves to

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
