Distinguish between a carbon-tax and a cap-and-trade strategy for reducing carbon dioxide and other so-called greenhouse gases (that are believed by many scientists to be causing global warming). According to the case‚ the carbon-tax and a cap-and-trade system are the best economic tool to employ to reduce emissions. As we know‚ taxes are the most important expense for a company or firm‚ if they would emit much more carbon dioxide and other gases‚ they need to pay more taxes on using carbon recourses. It

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute(AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium‚cobalt‚ molybdenum‚ nickel‚ niobium‚ titanium‚ tungsten‚ vanadium or zirconium‚ or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0

CaCO3 (s) + 2HCl (aq) ----------- CaCl2 (aq) + CO2 (g) + H2O(l) AIM: The aim of this investigation is to experimentally determine the molar mass of carbon dioxide (CO2) by measuring its volume and calculating its mass. CO2 which we will measure will arise as a product of a chemical reaction between Calcium Carbonate (CaCO3) and Hydrochloric acid (HCl) as it is shown in the chemical equation above. Once

Activated Carbon Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface

Unit 4: Carbon Nanostructures Carbon Structures: • Carbon contains six electrons with electronic structure: (1s2)‚ (2s)‚ (2px)‚ (2py)‚ (2pz). Outer s orbital together with three p orbitals form the chemical bonds of carbon with other atoms. • Conventionally‚ solid carbon has two main structures called allotropic forms: diamond and graphite: - Diamond is tetrahedrally bonded through sp3 hybrid bonds that form a 3D network. - Graphite has a layered structure with each layer called graphene formed

Carbon is denoted by the symbol C‚ is part of group 14 on the periodic table‚ and is the fourth most abundant element in the universe (by mass). Carbon has an electron configuration of 1s2‚ 2s2‚ 2p2. With 4 valance shell electrons it is expected to form 4 bonds‚ this means carbon is tetravalent. However the s orbitals do not form the same type of bond (with other atoms) as the p orbitals‚ this is because their shapes are different. For example CH4 would have the following bonds: C(s)-H(s)‚ C(s)-H(s)

STRUCTURAL MATERIAL: CARBON FIBER Carbon Fiber is a structural material of graphite which is an allotrope of carbon. Therefore Carbon Fibre consists of carbon atoms in an atomic structure similar to Graphite. Carbon Fibre is composed of filament threads and within these threads are an accumulation of thousands of fine Carbon filaments. A filament has a diameter of approximately 5-10 micrometers. (Madehow‚ 2012) Due to the substantial stability in bonding between Graphite and Carbon Fiber the structure

Why life chose Carbon? It is the second most abundant element in the human body-18% of the wet weight. Molecules based on carbon-known as organic molecules because of their occurrence in living matter-constitute the majority of molecules found in living organisms from plants to people. 1 of the 4 special features of carbon is that carbon atoms are able to bond with each other to form extended chains-sharing pairs of electrons with neighbouring carbon atoms which allow the formation of stable covalent
