Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

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

Assignment- 1 Evaluate and Determine Marketing Mix 1. Introduction about Braaap: At age 16 Smith had a vision to establish mini motocross Superlight MX in Australia. In 2004 he identified the need to develop an affordable Superlight pit bike which could be ridden and jumped confidently by adults. Evermore determined Smith set about designing his own bikes and researched the market extensively. He frequently travelled to mainland Australia where he participated in motocross events to build his

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

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

The student will the complete a story mountain and use it to assist them in retelling the plot of the story. The teacher will make anecdotal notes to determine the students ability to orally retell a story using the given “Uh-oh . . . Phew “ strategy and the story mountain. The teacher will assist the student in writing notes on the story mountain. Activating Strategy:

endothermic reaction happened everywhere around us. Basically exothermic and endothermic reaction is transfer energy to the surroundings and take in energy from the surroundings (BBC GCSE bitesize). If the reaction forward ，then is exothermic.If the reaction is the backwards ‚then is endothermic. When a reaction take place‚ the energy started to transfer from different object to the surroundings or take away energy from the surroundings. When temperature started to change.
