But in order to strike an enemy ship‚ it has to take plunge in deep sea and remain submerged for a period between 24 to 48 hours! How the submarine

the benefit of climbing beans. And they are easy to harvest! The Organic Farmer A large section of the Kenyan population is unable to afford high protein food with adequate proteins‚ such as meat and eggs. This is where beans play a very important part; they are a cheap source of proteins. Unfortunately‚ the production of beans in most parts of the country is declining. The problem is the lack of good seeds . A survey by The Organic Farmer at the beginning of March this year indicated that most of

In this experiment‚ the instructor requested that 4 ml diethyl ether be added to the solution in the conical vial after step 4 to help better see the difference between the organic and aqueous layer. During step 4‚ NaCl(aq) was also available‚ and was used instead of water. The last test involving NaI was not performed. Results A volume of 1.54 ml of

Organic Food vs Non Organic Food In today’s society you walk into a grocery store and you always have the option of organic or non organic food. There are even grocery stores dedicated to organic foods like Trader Joe’s‚ Sprouts and Whole Food market. I personally have gone organic and will never go back to eating or drinking non organic food. Organic food may be pricey but less hormones‚ less cow puss and blood in your milk‚ and less pesticides. The controversies about organic food vs non organic

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few. Molecular geometry is associated with the specific orientation of bonding atoms. A careful analysis of electron distributions in orbitals will usually
