From the results recorded it was identified that activity A and C had exothermic reactions‚ whilst activity B had an endothermic reaction. Each of the activities had initially begun with 23.4/8/9oC‚ however‚ within one minute of adding the 2nd reactants‚ the results began showing‚ as seen from the graph. Activity A and C had risen in temperature‚ with A gaining 4oC and in total of 2 minutes having the temperature of 27.9oC along with C increasing by 2.2oC and within 2 minutes of the experiment having

The order that the liquids were in was blue‚ orange‚ green‚ yellow‚ and red. On our first trial‚ we only put in blue‚ green‚ red‚ and yellow mixtures inside the test tube. Before we even put in the orange solution‚ the yellow liquid started to mix in with the red solution. It meant that the yellow sugar water was more dense than the red sugar water. On our second trial‚ we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube‚ we decided

experiment the objective was to perform a Diels-Alder reaction using cyclopentadiene and maleic anhydride to synthesize the product‚ cis-Norbornene-5‚6-endo-dicarboxylic anhydride. The Diels-Alder reaction is one of the most important reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon bonds‚ mostly

Conclusions At the end of Part A in this experiment‚ it can be determined that Sodium Chloride had the highest amount of conductivity tested by all groups. On the graph above‚ the data shows that NaCl (sodium chloride) held the highest amount of electrical conductivity for all groups and on the table it reads the highest numbers across its row. Also as seen in the data above‚ ethanol had the lowest amount of conductivity with sucrose‚ acetic acid‚ ammonia‚ and MgCl2 following in ascending order

Solubility and Stoichiometry I. Introduction The first purpose of this experiment is to apply solubility rules to choose two of eight given reactants to do a precipitation reaction. The second purpose is to use stoichiometry to calculate how much of a reactant will be used in a precipitation reaction‚ assuming that the amount of product is given‚ and to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. The other purpose of this experiment is to practice the

Getting To Know The internet is a large computer network that is made up of thousands of networks worldwide. No one knows exactly how many computers are connected to the internet. But it is certain that this number is in millions and is increasing at a rapid rate. Internet Connection In The Philippines There is no single person or organization in charge of the Internet. There are organizations that develop the technical aspects of this network and set standards for creating applications

The purpose of this experiment was to determine the speed at which a reaction took place between an iodine and hydrogen peroxide solution. In addition to a change in concentration‚ a change in temperature and a catalyst variable was also introduced to conclude whether or not their presence affected the overall speed of the reaction. In order to determine the effects of these variables‚ several iodine and hydrogen peroxide reactions were prepared‚ (all at varying temperatures‚ volumes‚ and concentrations)

the wooden originals. The temples had painted decorations and low-pitched wooden roofs. Columns had ornamental capitals—the top of the column—in one of three designs. The simplest‚ Doric‚ consisted of columns with plain molded capitals and no base. Ionic capitals were decorated with a pair of scrolls‚ known as volutes. Corinthian capitals‚ the most ornate‚ were decorated with an inverted bell-shaped arrangement of leaves. Prime examples include the Parthenon and Erectheum‚ in Athens. From 100 B.C
