Experiments in Physical Chemistry - 6th Edition Review

Experiments in Physical Chemistry - 6th Edition ReviewIn the 6th edition of Experiments in Physical Chemistry, you will learn all about organic molecules, chemicals and their reactions. If you're an expert chemist who prefers to use some of the simpler techniques while making use of the more advanced procedures, this book is for you.This edition of Experiments in Physical Chemistry is nothing new; it is a reprint of the previous editions. There are several improvements in this edition that can't be found in the first and second editions. For example, they have added a chapter on bio-organic chemistry, which focuses on the synthesis of numerous valuable compounds such as the polysaccharides and sugars, the bacterial super-antibiotics, and many others.To make this book suitable for the novice chemist, the same experts have refrained from adding unnecessary new information in this edition. They still cover all the bases and provide you with ample material to keep you busy in the lab. Th e book contains both lab and laboratory instructions. The lab instructions are short and sweet, while the laboratory instructions are more in depth and elaborate.Experimenters will find that the new chapter on the theta basis exchange of monomers is very useful. They have chosen to include this chapter because inorganic chemistry is all about exchanging a set of atoms.Experimenters may not be aware of this but if the reaction they are trying to perform has a step where a few atoms have to be changed, then the transformation of the experiment will take much longer. As a result, the actual experiment must go on for a longer time than expected. So, if your experiment needs to go for a long time, the utilization of the experiment to use the maximum possible sample size is a must.Experiments in Physical Chemistry was one of the first books Iever purchased. Although I am not sure whether I went through the whole first edition or the later editions but I surely want to read the new version . I have tried out the book a couple of times and I had never found any errors. For example, I had a hard time figuring out why the experiments using glucose had a shorter experiment time than the experiment using fructose.One thing I am unsure about is the difference between lab instructions and laboratory instructions. I suspect the latter are the better and cheaper options but let me find out for myself. I am actually planning to buy the second edition of Experiments in Physical Chemistry. Now, if only I had thought of that while making my purchase!

The Importance of Hydration for Singers

The Importance of Hydration for Singers Shanika There are many important reasons to stay hydrated for general health, but for musicians particularly vocalists hydration is a key to success. In order for your body to function properly, hydration is vital. Our bodies are made of 70% water, and hydration affects every organ and cell in your body! Hydration for Singing Singers need to take extra precautions, because your entire body is your instrument. With excessive use, vocal cords can be easily damaged, as they are made of extremely delicate tissue. If you allow yourself to become dehydrated, your voice may suffer. Whether we are speaking, singing, or humming, the sound is created by the vibration of our vocal folds. Mucus protects these vocal cords, and staying hydrated ensures that everything is working properly. If you are even slightly dehydrated, your vocal fold tissues may become dry and even permanently injured. However, simply drinking water right before a performance is not good enough! In order to keep your vocal folds truly hydrated, you need to be drinking water throughout the day. Keeping hydrated will also help to keep your throat and mouth lubricated, making speaking and articulation easier as well. Signs of Vocal Dehydration If you are using your voice professionally, or even as a casual singer, you should be able to recognize these signs of dehydration: Dry/scratchy throat The need to clear your throat often Dark yellow urine You require more effort to use your voice Excessive thirst Benefits of Hydration for Singing When you keep properly hydrated, you are setting yourself up for good voice quality. Most experts recommend drinking 8-10 eight-ounce glasses of water daily to ensure this. What to Watch Certain things can cause dehydration, as well. Here are a few to watch out for, as they may reduce your bodys fluids: Caffeine and alcohol intake should be decreased, as both act as diuretics. Air conditioning and heaters tend to dry your secretions. Using a humidifier during sleeping hours to offset these effects may be helpful. Dry climates, especially in the winter months, are dehydrating to your body. If you are in a dry environment be sure you are keeping hydrated with adequate water consumption. Some medications can dry out your vocal cords. Try to avoid medications such as antihistamines and decongestants. Milk and sugary beverages, as well as carbonated beverages, may cause thickened mucus secretions. Once you fully understand how to stay hydrated, monitoring yourself will require little to no effort. And once you see the positive effect it has on your vocal health, keeping that habit will seem like a no-brainer! Photo by vicio2 Interested in Private Lessons?
