Change of Reaction Purpose of Experiment The purpose of this experiment is to determine the enthalapy change for the displacement reaction: Zn(s) + CuSO4(aq) Cu(s) + ZnSO4(aq) Hypothesis With this experiment I can also not make a hypothesis‚ because we did actually not do the experiment‚ but we were told that the temperature would make a sudden drop ‚ but we can measure the ΔT of the surrounding. The reaction is endothermic because the system will take in energy. During the reaction bonds

Psych 102 Reaction Paper #1 Raven Smith Northern Illinois University The first article “Even Geniuses Work Hard” was generally about the two different ways in how people observe intelligence and learning‚ fixed and growth mindset. Students with a fixed mindset do not like work. They believe that if you have the skill then everything should come logically. Students with a growth mindset are more likely to respond to original problems by continuing to be involved‚ trying new tactics‚ and using

Summary The writer started his article by describing a group of people called Tuvans‚ who lives in a remote area in the Republic of Tuva‚ in Russian Federation. The importance of this group came from the fact that they are speaking Tuvan‚ a language consider by linguists to be among a group of languages that are

Introduction Twelve O’clock High is a 1949 film about the 918th Bomber Group‚ known as the “hard luck” group‚ and their evolution from a demoralized group to a reliable and accomplished group. American bomber groups were flying bombing missions in daylight from England‚ in order to increase accuracy. With Brigadier General Frank Savage as the new leader of the 918th‚ the efficiency and effectiveness subsequently increases. As a replacement for Colonel Davenport‚ who over identified with the men‚

A2 Chemistry Coursework Section 1 Aims: I aim to find out the order of reaction with respect to [H2O2] and [2I-]. I aim to find out the activation enthalpy of the reaction by finding the rate of reaction at different temperatures using the Arrhenius Equation. The experiment will go as follows: Into a conical flask put 15cm3 of distilled water and add 2cm3 of [X]moldm-3 potassium iodide (KI) solution and 1cm3 of 2moldm-3 sulphuric acid. Then add to this 2.5cm3 of 5vol (0.42moldm-3) hydrogen

REACTION PAPER It is said that effective teacher will use both assessment and evaluation regularly to improve student learning and to guide instruction. Indeed‚ both have pivotal roles in the teaching-learning process yet‚ somehow they do differ in many ways. Assessment and evaluation measure whether or not learning and/or learning objectives are being met. One could look at assessment and evaluation as the journey (assessment) versus the snapshot (evaluation). (Sue Watson‚ 2009) Assessment requires

The objective of this lab was to. First‚ we measured out 2.00g of granular zinc and 2.03g of iodine crystals and added them together into a boiling tube‚ which we labeled "R". After‚ we added a boiling chip into a large test tube labeled "P" and we also labeled an empty regular sized test tube with a "C". When we added 5mL of acetic acid to tube R‚ the solution turned red and was hot. After we add 30 drops of the red solution into tube C and continued to swirl tube R‚ the solution became
