Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

Reaction Paper The story “Where Are You Going‚ Where Have You Been?” is an exciting story. I would explain it as a car crash; people want to turn away but they keep looking. No one ever wants to hear a story about a young girl being kid napped or raped but when people do see it in the news they want to know all the details and that’s kind of how I felt reading the story. I felt that it was exciting because I didn’t see what was coming next; I thought the story would have been about a daughter and

Reaction to Dr. David Callahan I was prepared to be interested in hearing this person speak‚ but when he started to list some “facts”‚ I started to tune out. The one that stood out for me was that‚ “billions of dollars have been lost for the music industry because of illegal downloading.” If people who downloaded the illegal music actually purchased it‚ yes- that would be more money in the big wigs pockets. However‚ many studies have shown (and I read another one on Techcruch right before seeing

A federal law was passed barring entry to all convicts and prostitutes. Before then‚ immigration was scarcely controlled. Over centuries different laws were passed in attempt to get the situation under control. Once the Immigration Law passed‚ legal immigration

Reaction Paper #2 Mediactive‚ Chapters 1‚ 2‚ & 3 In today’s media world‚ we have the ability to access innumerable amounts of information. Such accessibility provides a positive impact on our lives‚ but at the same time leaves us vulnerable in conforming to information that is not trustworthy and false. We must not be passive when we are subjected to the various types of media‚ we must be active. Meaning we must analyze the information at hand and use our reason to come to a conclusion as 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

“REACTION PAPER” The title of this novel "Noli Me Tangere" is a Latin words meaning in tagalong “Huwag Mo Akong Salingin”. Jose Rizal‚ our national hero is the writer of this novel‚ where in‚ this novel was written during his time‚ where in‚ the exact year was 1884‚ he was in Madrid taking up medicine when he write this novel. When he finished his course (Medicine)‚ he went to Paris and continues writing this novel. In Berlin‚ Jose Rizal finished the last part of this novel. This novel was written

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

Reaction Paper 2 In the 4th chapter of “The Land Looks After Us” Martin starts by talking about a weather doctor that the tribe turned to for guidance after a total eclipse blocked out the sun. Though he was ill he helped and went into a trance which allowed his soul to find out what was going on. What he ended up seeing was a vision of god and all that neat stuff. After he became a prophet‚ I think what martin was trying to address with this story was that religion was not only spreading but
