Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

Are organic foods actually safer than traditionally-produced foods? Pesticide free preparation is a thorough arrangement of harvest administration and nutrient manufacturing that syndicates best ecological applications and critical level of multifariousness. While organics have become more desirable by the consumers‚ nonetheless‚ they don’t hold more nutritional value as opposed to non-organic foods. In the words of Brantsæter et al.‚ “Consumer preference for organic food is motivated in part by

support organic food production. Ladies and Gentlemen‚ Have you ever thought about the food you eat? Of course you have‚ we all do. We think about the taste‚ the ingredients and the health benefits‚ but we don’t question where the food comes from and we barely think about all the chemicals and toxins added to it‚ because most foods that we are surrounded with are all the same‚ most food companies that we enjoy are not organically produced‚ but are just easier to obtain. We see organic food so

Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

HOW FAST ARE CHEMICAL REACTIONS? THEORY The study of reaction rates‚ how fast or how slow a reaction takes place‚ is known as chemical kinetics. The rate of chemical reactions varies greatly. Some reactions‚ such as the explosion of an atom bomb are uncontrollable. Reactions like the decay of radioactive carbon (14C) are so slow that it takes centuries to see any noticeable change. Between the two extremes are reactions that can be measured in the laboratory. There are several factors that

Kinetics‚ A Clock Reaction Abstract The purpose for the experiment Chemical Kinetics‚ a clock reaction is to figure out the reaction rate of a solution regarding its concentration‚ temperature‚ and also determine the effects of when a catalyst is present. The experiment resulted that the concentration‚ as well as its temperature can affect the rate constant inversely the outcome of the rate constant. By conducting the experiment‚ it is also discovered that the rate order of the reaction resulted as

Introduction – Lab Report What is a Chemical Reaction? A chemical reaction is a change in matter that produces one or more new substances. A chemical change or reaction occurs when bonds are broken and new ones are formed. The formation and dissolution of these bonds are dependent upon environment changes. Even without the usage of microscopes‚ chemical reactions are usually apparent to the naked eye. The two main kinds of changes that one can observe are the formation of new substances and changes

Enzymes Reactions to Changes in Substrate and Inhibitors Benjamin J. Mora Coronado University of Texas Rio Grande Valley at Edinburgh Abstract Purpose for the experiments was to test the enzymes in various scenarios and see how changing this would affect the rate of reaction. The enzyme source used in the experiments was Turnip Extract. Concentrations of Turnip extract for activity 1 where o.5ml‚ 1.0ml‚ and 2.0 ml as for the rest of the activities 2 Through 4 stayed at a consistent concentration
