Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

Neutral Curriculum What is a neutral curriculum? A neutral curriculum is that curriculum that does not cover all aspects of coping with day to day life. This type of curriculum does not allow the students to draw their own conclusions about specific lessons that are being taught. As individuals‚ we need to be well rounded. This type of curriculum will not allow the students to conquer other areas that will encourage them to move forward in their education spiritually. They must understand the importance

Assignments in Science Class X (Term II) 4 Carbon and its Compounds IMPORTANT NOTES 9. Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

Book Discussion Questions for Stuck in Neutral by Terry Trueman 1. Do you think the title fits the book? Why or why not? I do think the title fits the book as the whole narration is about the character not being able to express loud and clear what he really felt due to a medical condition. He expresses how this feeling of impotency make him feel like he was “stuck in neutral”- not advancing or progressing‚ just “being”. 2. Why do you think the book was written in the first person? I personally

EXTRACTION OF METALS SUMMARY Most metals exist in compounds in rocks in the Earth’s crust. Many of these ores contain oxides or sulphides of the metals. The compounds need to be reduced to produce the metals as elements. Metals are very useful to us because of their special properties. Reduction means removal of oxygen or gain of electrons. Carbon is a good chemical reducing agent because it readily combines with oxygen‚ but it is only useful for the metals below it in the Reactivity

MCOPS‚ Manipal ANALYTICAL METHODS FOR RESIDUAL SOLVENTS INTRODUCTION: Organic solvents are routinely applied during synthesis of drug substances‚ excipients‚ or during drug product formulation. They are not desirable in the final product‚ mainly because of their toxicity‚ their influence on the quality of crystals of the drug substance and their odor or taste‚ which can be unpleasant for patients. To remove them‚ various manufacturing processes or techniques (usually under

Extraction of metals The History of Metals. Metals have been used by people for many thousands of years. Gold and silver‚ found as native metal‚ were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age‚ but gold and silver are too soft to be used as tools. The first really useful metal to be discovered was bronze. This began the Bronze Age. Bronze was used extensively for tools and weapons in Asia and Africa from 4‚500 B.C. (6‚500 years

John Updike: “Separating” John Updike has been credited by many as one of the greatest American novelist of the twentieth century. He has written many novels‚ poems‚ short stories‚ and essays. Updike earned many awards for the many works he created. One work of his called‚ “Separating”‚ is a great example of a man in a somewhat mid-life crisis where he feels he wants to leave his wife for another woman. In the end there is so much more than that when Richard the husband realizes it will not be as
