Claveria‚ Noveamie C. San Andreas The San Andreas movie is a good movie and a nice wake up call for everyone. I’m very thankful that this movie is released in time for the earthquake preparedness of our country. You might get tips on how to survive or maybe get tips on how you can die if you don’t prepare for it. I watched this film in our classroom during our Science subject. I enjoy ed the movie because everyone shouting “aaaaahhhhh” whenever there’s explosion and destruction hahaha. The action

diseases‚ especially cancer. ANTIOXIDANTS are molecules that can donate an electron to another molecule that has an unpaired electron‚ AKA a free radical.. By donating an electron‚ antioxidants help stop the chemical reaction called oxidation. Think of rust- that’s an oxidation reaction. So basically‚ what antioxidants are important for is to help keep your body from rusting (aging). Are We Receiving the Nutrients We Need? Are all Supplements created equal?

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

Jose Rizal The movie tells the life and struggles of Dr. Jose Rizal‚ our national hero and martyr of the Philippines. It covers his life from his childhood to his execution at the hands of the Spanish forces colonizing the Philippines. The film show what kind of life we have under the Spanish colonizer and how the friars use the religion to control the Filipinos. Filipino’s life was full of misfortunes. The Filipinos were unfairly treated and discriminated by the Spaniards. This is the reason

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
