values that have trailing zeros only to the left of the decimal point are ambiguous and should be expressed in scientific notation. We must take note that the chemistry textbook (Silberberg 6e) states that placing a decimal point to the right of some trailing zeros (example: 300.) will make the zeros significant. However in General Chemistry‚ we do not follow this rule. If we want to write a whole number with trailing zeros we must use scientific notation to show which zeros are significant. When

Chemistry 121 Colligative Properties Lab Demonstration of Selected Calculations from Choice I Determination of Kf for Naphthalene To determine the Kf for naphthalene‚ we need to find the difference in the freezing point of pure naphthalene and the solution of 1‚4-dichlorobenzene in naphthalene. Let’s say that we did this experiment‚ used 1.00 g 1‚4-dichlorobenzene in 10.00 g naphthalene‚ and found that the freezing temperature of pure naphthalene was 78.2°C‚ while that of the solution was 75

Toxicological Chemistry - relates the aspects of toxicology to the chemical structure and reactivity of the toxin. It is concerned with the chemical interaction of the toxin with the receptor that gives the physiological response. The ultimate aim is to relate functional group chemistry of both toxin and receptor to the interaction Toxicity - the degree to which a substance causes damage to an organism Acute toxicity - the adverse effects resulting from a single exposure‚ or exposure over

reactants used and the amounts of products formed in a chemical reaction”. Basically‚ Stoichiometry is the science of counting and studying the relationship between the amounts of the reactants to the product. To think of stoichiometry outside of chemistry‚ imagine a bookshelf. To assemble the bookshelf you may need 3 planks of wood‚ 1 giant plank of wood‚ and 20 nails. Even though the amount of the reactants is high‚ the product would be only one bookshelf. Stoichiometry is basically studying the

QUESTION: Citing examples identify the ways in which companies are increasing environmental sustainability. INTRODUCTION. In environmental terms‚ sustainability implies that an action can be continued indefinitely with little or manageable impact on the environment. Because the health of the environment is closely linked with the health of the society in general‚ sustainable practices ensure that the earth’s resources will be available for future generations to enjoy‚ and that there will be an

Chemistry of Fireworks By Anuradha Sahu Everyone enjoys the amazing firework shows on the Fourth of July with the beautiful vibrant colors and sparks every year. Fireworks have been part of this world for a very long time. They have been used for enjoyment and for signalling purposes. Every culture has their own significance and use of fireworks. But all fireworks have something in common; the chemistry that makes them work. No matter where you find them‚ they are made up of the same compounds
