CONTENTS RESEARCH 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…

sites of catalytic activity. • Other coordination compounds in biological systems include chlorophyll and vitamin b12, a complex of cobalt with a macrocyclic ligand known as corrin. • Hemoglobin also has iron-porphyrin complexes, its role is in oxygen carrier in living organisms. Coordination compounds in industry The applications of coordination compounds in chemistry and technology are many and wide-ranging. • In dyes and pigments, the shinning and intense colors of many coordination…

water. Water is combination of two atoms, oxygen and hydrogen. When two hydrogen’s bond with one oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between two non-metals, the molecules share electrons to achieve full valence shells for the molecule to be stable. In the case of water the two hydrogens and one oxygen share electrons to get the hydrogen…

dangerous especially in infants and babies. When nitrate or nitrogen enters the water we drink our bodies react very poorly. The nitrates will attach to your hemoglobin. This is very threatening because when it attaches it doesn’t allow the cell to carry oxygen. It is less threatening to adults, but it is very bad for younger kids. No babies have died from this in the United States because of EPA 's rule that drinking water can have 10 ppm of nitrogen. In Europe; however, their water has 2,000…

Since the naming of the dinosaurs in 1842 it has been thought that their metabolisms were similar to current day ectothermic, cold blooded reptiles., In the 1960’s- 1970’s; however, it started to become apparent that an endothermic metabolism (warm blooded, like mammals) is more conformable with new evidence and observations. Originally, predictions on the paleothermometry of dinosaurs was based on the physical performance such as the estimation of running speed from trace fossils as well as…

what the sun is composed of, ultraviolet rays, and ozone depletion needs to be understood. Our Sun is the central part of our solar system; if the sun didn't exist several things wouldn't occur: the process of photosynthesis would not take place, oxygen cannot be created, thus, life cannot be present. The Sun is mostly composed of “ hydrogen and helium”(Helmenstine). Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion making the Sun a…

Prior to the Great Oxygenation Event (GOE) there was little oxygen in the atmosphere. Oxygenation of the atmosphere occurred in two steps, at the beginning and end of the Proterozoic eon (Frei, et al., 2013). In the GOE the surface oceans began to become oxygenated (Holland, 2006). The Second stage of oxygenation is known as the Neoproterozoic Oxygenation Event (NOE) and occurred after the 650-635Ma in the Marinoan glaciation (Sahoo, et al., 2012) (Feulner & Kienert, 2014). The NOE is thought to…

the Most Important Element Alrecus What is Oxygen? Oxygen is one of the periodic table elements. Oxygen is also a gaseous chemical. Oxygen makes up more than twenty percent of the Earth's air. Oxygen is a dry and unscented. Oxygen is exceptionally receptive. Oxygen was found interestingly by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an 112, freely, found oxygen in 1774 and distributed his discoveries that year, three years before Scheele distributed. Antoine Lavoisier,…

Catalase, is an enzyme where hydrogen peroxide is broken down to water and oxygen ; which causes a response. Found in a lot organisms that live in the surrounding of oxygen, catalase can fend off the buildup and protects cellular organs from damage by peroxide, which is always produced by many reactions. The catalase enzyme is critically important to are health, it can be found in nearly every living organism exposed to oxygen. In the catalase lab we measured the amount of catalase in each…

regions in the brain can affect or have negative effect on oxygen and carbon dioxide levels in the bloodstream. The body responds to low oxygen when there is there is dilation of blood vessels, which decreases blood pressure. This is also known as vasodilation. Thus, the blood vessels relax and widens enabling greater blood flow or the tissue allows greater perfusion by the use of nitric oxide. Hypoxemia which is also known as low oxygen level can affect the brain, liver, and other organs can…
