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 Bond

Rationale Abstract: This investigatory project was conducted to test the affectivity of organic and synthetic fertilizers when apply on okra plant. It also aims to test whether‚ which is better to use between the two fertilizers. In order to conduct the study we have used okra seeds‚ polyethylene bag and cemetery soil as organic fertilizer‚ synthetic fertilizer‚ and black soil‚ labeled it as setup A (Organic Fertilizer) setup B (Synthetic Fertilizer). Then we observed the changes in the plant for

Elements and compounds are a result of the actions of the valence electrons. There are three types of bonds that I have learned about in the bonding comparison lab. These bonds include ionic‚ polar covalent‚ and non-polar covalent. Each of these bonds and the element compounds connected to them has individual solubility‚ conductivity‚ melting point‚ and volatility levels. The three element compounds that will follow are sodium chloride‚ sucrose‚ and p-dichlorobenzene. Sodium chloride is an ionic

Title: to get organic food Specific purpose: Organic food advocates claim that organically grown foods are safer and more nutritious than foods raised with non-organic methods such as pesticide and non-organic fertilizer use‚ or antibiotic and hormone use. Thesis statement: Many people just don’t trust these chemicals and don’t want to put them into their bodies. Since virtually all non-organically produced foods contain residues of pesticides‚ fertilizers and other chemicals‚ the only way to

Hoàng Hồng Thủy – LQT40A THE DIFFERENCES BETWEEN BRITISH ENGLISH AND AMERICAN ENGLISH INTRODUCTION Those people who complain about the difficulties of learning German‚ don’t know how lucky they really are - they only have one language to master. Admittedly‚ there are regional differences of dialect in German-speaking countries‚ but the non-native speaker who has learned Hochdeutsch (high or standard German) should have no problems in making himself understood by citizens of Germany‚ Austria or Switzerland

The compound is the substance that can be two or more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if
