Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double

Institute of Technology; 2Students‚ Chm145L/A41‚ School of Che-Chm-BE-MSE‚ Mapua Institute of Technology ABSTRACT The experiment was conducted to accomplish the following objectives. The first objective aims to synthesize an isomer of alkenes. This was done by converting maleic acid to fumaric acid. This conversion was accomplished by applying a heat-catalyzed reaction on maleic acid diluted in distilled water and mixing it with HCl using a reflux set-up. A reflex set up is a distillation set up wherein

Syl Rogers Bio 210 Comparing Fermentation Rate of the S. cerevisiae Yeast in the presence of MgSO4‚ NaF and Sodium Pyruvate Hypothesis In the fermentation of rate of yeast‚ S. Cerevisiae‚ there will be a higher/ faster rate of ethanol production‚ However‚ using catalytic enzymes would make the rate more faster‚ and MgSo4 will have a higher rate of CO2 than that of NaF and Sodium pyruvate as it act as a more better catalytic enzyme than the others.

VARYING EFFECTS OF ENZYME CONCENTRATION ON REACTION RATES OF MALATE DEHYDROGENASE CELL BIOLOGY 13 NOVEMBER 2007 Enzymes are biological catalysts. They are proteins that speed up reactions with low concentrations. These enzyme proteins are made up of linkages of amino acids. The links coil‚ and coil again forming a tertiary structure. This structure has a groove in it called an active site. The active site is

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass

order of their reactivity based on displacement reactions‚ reduction of their oxides by hydrogen or carbon‚ the relative ease of decomposition of their compounds and reactions with oxygen‚ dilute acids and water. The higher up a metal is in the reactivity series‚ the more reactive it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them in the order of their reactivity

itioned by Transfer John B Watson and Rosalie Rayner conducted an experiment in the 1920’s. The experiment included an infant named Albert‚ who was unemotional and hardly had any exposure to a stimulus to cause an exuberant emotional reaction. Emotional test had been conducted on Albert; a stimulus that was used in the initial experiment‚ items such as a white rat‚ dog‚ rabbit‚ and other various “furry” items‚ he showed no fear in any instance. Starting at nine months old Albert was exposed to a

materials and soap making Soap making requires two major raw materials: * Fats and oils Fats and oils are esters of fatty acids and glycerol. These are obtained from natural substances which are classified into three: a. Nut oils Cold process soap making is the most suitable for this type of oil which is also characterized by large proportion of fatty acids. Nut oils saponify easily with strong alkali soulution. Example: coconut oil‚ palm kernel oil b. Hard fats Slow-lathering soaps

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min and
