THE CLASSIFICATION OF CHEMICAL REACTIONS Danny Bhatt SCH3U0-G Mr. Gandhi Wednesday‚ April 1st‚ 2014 INTRODUCTION The purpose of this lab is to determine the different types of chemical reactions and differentiate between them based on similar characteristics of each set category. In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and

Physical properties of organic compound Low boiling point group: alkane‚ alkene‚ alkyne and ether Boiling point is the exact temperature that the state of compound change from liquid to gas‚ which need to break the intermolecular forces. The stronger the intermolecular forces‚ the higher the boiling point. Since straight chain alkane‚ alkene and alkyne only experience dispersion forces‚ the compound with more carbons have higher boiling point as more carbons contribute more forces. Branched

Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose

Write an explanation of how any two factors affect the rate of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature

THE BASICS OF SUPPLY AND DEMAND - EXERCISE 1) Use supply and demand curves to illustrate how each of the following events would affect the price of butter and the quantity of butter bought and sold: a. An increase in the price of margarine. b. An increase in the price of milk. c. A decrease in average income levels. 2). Use Supply and demand curve shifts to illustrate the effect of the following events on the market for apples. Make clear the direction of the change

Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.

1.3.c Risperidone vs Haloperidol: Evidence proves that risperidone is often more effective in the treatment of psychosis than the most commonly prescribed typical psychotic medication‚ haloperidol‚ which is included in the current list of WHO essential medications with chlorpromazine and fluphenazine. In multiple studies‚ risperidone is more likely than haloperidol to improve scores in the Positive and Negative Syndrome Scale (PANSS)‚ reduces relapse rates of psychosis‚ improve cognitive function

LABOR: One of the four basic categories of resources‚ or factors of production (the other three are capital‚ land‚ and entrepreneurship). Labor is the services and efforts of humans that are used for production. While labor is commonly thought of as those who work in factories‚ it includes all human efforts (except entrepreneurship)‚ such as those provided by clerical workers‚ technicians‚ professionals‚ managers‚ and even company presidents. Labor Labor is the mental and physical efforts of humans

PHYSICAL SCIENCE physical change-changes affecting the form of a chemical substance‚Physical changes are used to separate mixtures into their component compounds Example:breaking glass Chemical changes- when a substance combines with another to form a new substance ‚called chemical synthesis. Example: burning wood Law of Conservation of Mass-The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations

hardened into hard solid mass. Water is one of the important ingredients of concrete. This is required not only for chemical reaction‚ but also for curing purposes. The chemical reaction of cement and water‚ in the mix‚ is relatively slow and requires time and favorable temperature for its completion. Depending on the quality and proportions of the ingredients used in the mix‚ the properties of concrete has enough strength in compression‚ but has little strength in tension. Due to this‚ concrete as such
