Trends in the Periodic table March 24‚ 2013 Four trends that will be covered: Atomic size Ionization Energy Electronegativity Electron Affinity Each of these has a group trend and a period trend A group trend refers to what is happening with the atom as you travel up or down a column of the periodic table. A period trend refers to what is happening with the atom as you move left or right across a row of the periodic table Atomic Size When discussing an atom’s size‚ usually the

|Chapter 5: | |Structure and Preparation of Alkenes. | |Elimination Reactions | Summary Alkenes contain the C=C functional group which can be prepared by 1‚2-elimination reactions such as: • dehydration of alcohols (- H2O) or • dehydrohalogenation of alkyl halides (- HX). Zaitsev’s rule indicates that the preferred product is the more highly substituted

In conclusion‚ after conducting the lab‚ the emergent properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the

CHEM 3305 - 001 Organic Chemistry 1 Dr Michael Findlater Spring Semester‚ 2013 Stereochemistry • Stereochemistry refers to the three-dimensional structure of a molecule. • As a consequence of stereochemistry‚ apparently minor differences in 3D structure can result in vastly different properties. • We can observe this by considering starch and cellulose‚ which are both composed of the same repeating unit. Stereochemistry of Starch and Cellulose Figure 5.2 • In cellulose

Being able to extract a compound or substance from a product or object will encourage us in being able to do the same in a similar manner with a tea solution. Extracting compounds is an important step in any kind of organic chemistry lab and will help us be better at accomplishing the experiment in a much faster and accurate rate than from before. Experimental To begin the experiment‚ a tea solution must be made by incorporating a tea bag into a beaker filled with almost boiling water and the

Organic food is defined as produce (animal and plant) that is grown without the aid of any chemicals or pesticides‚ this means the animals are fed organic feed and the plants are grown in a very different way to most foods we see at the supermarket. Many people purchase organic food because they think that the nutritional benefits will make up for the extra money that you spend. Lots of people say that the manufacturers of organic food lie to us when selling these products‚ they say that there aren’t

Mechanistic and Organic Structure ORGANISATIONAL BEHAVIOUR PEER ASSESMENT WK 11 14th Oct‚ 2012 Name: Nicholas Roberts Organizations are viewed as systems in need of control‚ authority and governance. A distinction is made between formal structure and governance structure‚ and a network perspective is adopted to investigate the correspondence between structures‚ and the functions these structures play within groups (Human Relations vol. 37). As a result‚ research carried

What is Organic? The word ’Organic’ means ’living’‚ and in practical terms‚ this means natural food that is grown and processed without chemical fertilizers‚ pesticides‚ herbicides or fungicides. Nothing unnatural is allowed so there are no growth hormones‚ antibiotics‚ preservatives‚ dyes‚ chemical coatings or irradiation allowed. There is no genetic engineering allowed in organic foods. Organic food is nothing else but good pure nutritional food - the way it used to be. Toxic overload
