initiate the melting and help to continue build a shield of greenhouse gases to maintain heat. Mining Carbonate deposits can be done with the following chemical reaction which illustrates a small scale gas extraction procedure: CaCO3(s) + 2HCl(aq) CaCl2(aq) + CO2(g) + H2O(l) Hydrochloric acid would need to be imported from Earth to supply the activities on Mars which acid is reacted with the rocks to generate CO2. Calcium carbonate minerals contained within the rocks of Mars have quantities of CO2

The Grignard Synthesis of 3-methyl-3-heptanol In this experiment‚ an example of an organometallic compound which has a carbon magnesium bond will be utilized to form a tertiary alcohol. Grignard reagents have been extremely useful in the synthesis of a large number of classes of organic functional groups. Although Grignard reagents are unstable and decompose in air and moisture‚ they can be prepared and used immediately with moderate difficulty in the undergraduate organic chemistry laboratory

December 19th‚ 2012 Ms. Kathleen Sylva Head Researcher Ceramic Artisans Dear Ms. Sylva‚ In ionic and covalent bonds‚ there are many properties that make up each bond. Ionic bonds between a metal and a nonmetal are stronger than covalent bonds‚ have high melting and boiling points‚ and can conduct electricity in water. This is because the electrons are transferred‚ completing the valence electron shell and making the atom stable. Covalent bonds between nonmetals have weaker bonds‚ low melting

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength

Why Is Calcium Chloride Powder Used Extensively As A Bleaching Agent? In simple terms‚ calcium chloride is an inorganic compound having chemical formula CaCl2 (H2O)x where x can be 0‚1‚2‚4 and 6. All the salts produced by calcium chloride powder has a unique characteristic that they are highly soluble in water. This helps in applications where you need to remove snow‚ ice‚ or frost from any surface or even simple dust removal. It can absorb moisture from the surrounding environment‚ which is also
