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

eInvestigating water potential of swede The aim of our experiment was to investigate the water potential of swede and then use our results to help us determine the water potential of plant tissue. This overall flow of water from a dilute area of high water potential to a more concentrated solution of low water potential across a partially permeable membrane is called osmosis. I predicted that the swede cylinders which are put in a test tube with a low potential of sucrose solution would become

Abstract Introduction An antimicrobial is a substance that kills or inhibits the growth of microorganisms such as bacteria‚ fungi‚ or protozoans (Antimicrobial). Antimicrobial drugs either kill microbes or prevent the growth of microbes. Disinfectants are antimicrobial substances used on non-living objects or outside the body. Ginger Figure 1 : Ginger (Studies Reveal Ginger Lowers Colon Cancer Risk) Ginger is commonly used around the world and has been employed in the treatment‚ cure‚ and

are called ‘Friedel-Crafts’ alkylations and acylations‚ named for Charles Friedel of France and James Crafts of the United States‚ who together developed the procedures in 1877. The Friedel-Crafts reactions are an important part of a synthetic chemist’s toolbox to this day. Friedel Crafts reactions‚ like their biochemical counterparts‚ require reactive electrophiles with significant carbocation character. One of the most common ways to alkylate an aromatic ring is to use an alkyl chloride electrophile

chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures were prepared in separate Erlenmeyer flasks. In the 250 ml flask .010M potassium iodide‚ .0010M

Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is no reaction. Also‚

Endothermic and Exothermic reactions A chemical reaction is a process in which one or more substances are chemically changed into one or more new substances. A chemical reaction may involve the motion of electrons in the forming and breaking of chemical bonds. Therefore when a chemical reaction takes place‚ energy is transferred to‚ or from‚ the environment. A Chemical reaction can either be exothermic or endothermic. Exothermic Reactions During an Exothermic Reaction a transfer of energy to the

‘The personal religious beliefs of Edward VI‚ Mary I and Elizabeth I explain the religious changes of the years 1547-66’ How far do you agree with this opinion? In these years we see much change to religion within England as it goes from Protestant to Catholic back to much more mild Protestantism under Elizabeth. I believe that Edward and Mary do these changes because of their religious beliefs and we see some significant changes under Edward and Mary‚ for example the change back to the Rome and

Laboratory III: Forces Problem IV: Normal and Kinetic Frictional Force I John Greavu March 13‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Abstract The dependence of two-dimensional velocity and position components on time as well as whether or not said components are constant was determined. Video was recorded of a ball being projected laterally and data of its flight were plotted. From analyzing the data and the corresponding graphs that followed‚ it was shown that while the
