where she discovered kevlor and had 28 patents till her 40 years tenure research scientist. Actually she was working with poly-p-phenylene-terephthalate and polybenzamide. STRUCTURE AND SYNTHESIS Kevlors are polyamide the general ring-like aromatic chains connected together to form…
QUESTION How does the length of carbon chains, specifically those related to alkanols, namely ethanol 1- propanol and 1- butanol, affect the heat of combustion? AIM To investigate how the length of carbon chains affect the heat of combustion and enthalpy, in order to determine which fuel would be the safest and most efficient to take on a camping trip. HYPOTHESIS If the number of carbon atoms in an alkanol is increased, then the alkanol containing the longest carbon chain will have a higher…
alkane which has been replaced by an –OH group (Chem Guide, 2003).The general chemical formula for alcohols is CnH2n+1OH (BBC, 2014).Alcohols are any of a class of organic compounds characterized by one or more hydroxyl (−OH) groups attached to a carbon atom of an…
plastic be the most used material for packaging in almost every industry. The word ‘plastic’ comes from the Greek plastikos which means easily shaped (Robertson, 2013). Plastic is the combination of many molecules that linked together as one long chain which made from polymers: poly (Greek) means many and meros (Greek) means part (Robertson, 2013). Raw materials of plastic are called feedstock which come from natural and synthetic resources, such as crude oil, natural gas, coal, cellulose,…
Carbon monoxide poisoning is fatal. Carbon monoxide binds to haemoglobin at the same site as oxygen – the iron atom within the haem group – however carbon monoxide will bind with a strength 200 times that of oxygen. This means that if carbon monoxide is inhaled it was always displace oxygen within haemoglobin. If oxygen can no longer bind to haemoglobin then the respiring cells of the body can no longer receive oxygen and will eventually die. When carbon monoxide binds to haemoglobin it causes…
alkenes and alkynes. The difference between these three groups is in the bond types between the carbons. Alkanes form only single bonds, alkenes form double bonds, and in alkynes there is at least one triple bond. Alkanes are hydrocarbons which is only contain single covalent bonds between carbon atoms. Alkenes are known as saturated hydrocarbon. This is because they have the maximum of covalent bonds per carbon atom. They have C-C and…
about The Carbon Cycle, I learned from this video the Carbon is the basic building block of life, and there are these atoms are unique in every place on earth. Carbons forms the flora and fauna the earth, and are also stored in the ocean and the atmosphere, and the planet 's crust. Carbon atom can spend millions of years moving through the ground in a complex cycle. This conceptual animation provides an example of the different parts of the carbon cycle. The arrows indicate the purple carbon…
The Carbon Cycle Addition of carbon to the atmosphere Respiration: Through respiration, carbon dioxide can be added to the atmosphere. Living organisms use respiration to turn food into usable energy. Aerobic respiration requires oxygen to take place, and produces carbon dioxide, releasing it into the air and atmosphere. The energy taken from the food molecules following digestion is used to fuel the organism, additionally when mixed with oxygen, releases carbon dioxide when exhaling.…
CO2 therefore they will change to carbon monoxide. The oxygen reacts with H to produce H2O these can be defined by incompelete combustion. Use Markovnikov's Rule to explain why Propan-2-ol is formed during the reaction between propene and steam. (A.C. 2.3) According to his role if a HX compound was added to an unsymmetrical alkene the H will bond to the compound. As propane is an unsymmetrical alkene and water has Hydrogen OH-H,therefore the H will join the carbon that has more H. This process…
The element Carbon is the fourth most abundant in the Universe. Here on Earth, Carbon is present in what we eat, in what we live and drive, and also in us. DNA is formed by two intertwined molecules around a Carbon chain. From the smallest protein chain in DNA to the largest mountain on the planet, Carbon is responsible for one of the most important cycles that allow humans to survive on Earth. The Carbon cycle is divided into Slow and Fast. During my lifespan, I will be able to directly affect…
