Summary
Emily Draper, Tom Oliver and Dave Adams’ article “A Low Molecular Weight Hydrogel with Unusual Gel Ageing” describes the unique characteristics of the hydrogel element. The authors suggest that the gel is suitable because of its transparent and light weight that makes it…

The watery substance in the hydrogel helps with the repairs of tissues and cells of the ageing persons to restore wrinkled skin units (Draper, McDonald and Adams 2015, n.p).
The article is educative since the authors give instances where the characteristics of hydrogel are important considerations when producing gel ageing. The authors also offer other essential applications of the hydrogel such as the absorption and removal of harmful necrotic and fibrotic tissue (Draper, McDonald and Adams 2015, n.p). This implies that the weight and absorbent properties enable the gel to function properly with the ageing skin particles through the removal of the fibrotic tissues. Another vital concept of the article is the author’s articulation of the formation of the hydrogel compound by analyzing the different elements of water and gel. This brings about the absorbent and low molecular nature that provides the unusual gel ageing property unlike the other ...Download file to see next pagesRead More

...CHEMISTRY QUESTIONS Presented Intramolecular forces operate within the molecules or fundamental units of a substance. This would include the attraction between positive and negative ions in a crystal of an ionic compound, the covalent bonds in a molecular substance as well as the covalent bonds linking atoms in a network structure, such as that of carbon (diamond).Metallic bonds are also classified as intramolecular forces (Frederick, 1979, P.63)Intermolecular forces operate between, rather than within, the molecules of a covalent substance. This would include the attractions exerted by one molecule of a molecular substance on another, such as the force of attraction between water molecules in ice ,the attractions between atoms... relative...

...x100 = 65.62%. 137x27 Question – 3 a. In 1870, Markonikov laid down a basic principle of chemistry that holds till today. The Markonikov Rule states that when a hydrogen halide (Hydrochloric acid, HCl being an example) reacts with an asymmetrically substituted alkene the hydrogen attaches itself to the carbon atom that has the larger number of its hydrogen atoms substituted. The halogen automatically attaches itself to the carbon atom having the least number of its hydrogens substituted. An example of such an addition reaction: Cl2HC=CH2Cl + HCl  Cl2H 2 C=CH2Cl2 Here the halide chlorine attached to the right hand side of the molecule that had fewer hydrogen atoms...

...Chemistry Question One A and B Properties of gold, cube Density of gold = 19.3g/ml A Mass 11.439g B Volume of water 5.1ml With gold cube = 5.7ml a) The graduated cylinder has an accuracy of 0.1 ml, the electronic balance has an accuracy of 0.0001 g. according to the measurements given on volume they are accurate according to the minimum readable measurement given by the cylinder. The measurement given on the mass seems not to be accurate because the minimum measure of mass according to the apparatus is 0.0001, therefore if the measure was exactly 11.439 g then this should have been written as 11.4390 g. b) Volume of the gold cube 5.7 – 5.1 = 0.6ml c) Density and mass find volume of gold cube Density = Mass/Volume Volume =...

...Chemistry Describe the configuration of an atom. An atom is composed of a nucleus. The atom also possesses atomic orbitals and energy levels which are made up of electrons. 2.) Explain the process of radioactive decay which takes place on (^14)(^6)C or what is known as carbon 14. A radio carbon such as carbon 14 will undergo a process of electron mission, therefore losing energy and moving ultimately to a place of chaos or entropy. The following formula will illustrate the radioactive beta decay which will act on carbon 14: ^14_6C------> ^14_7N+e 3). Utilize the S P D orbital system to describe Potassium. An orbital is essentially a theory of something rather than an actual something. This orbital is said to contain...

...Hydrogen Introduction Hydrogen is one of the essential elements of life however very few individuals understand its complex series of uses. While itwas first detected as early as the 16th century, it wasn’t until nearly two-hundred years later that it was rediscovered and given its chemical name. Hydrogen combines to form a countless number of compounds that position it as a cornerstone to life in the universe. It is an essential element in things as essential as water, as small as healing cuts and bruises, and as large and industrial as oil refinement. This essay examines the historical background of hydrogen, its chemical formula and elements, as well as its use in compounds that make up the fabric of our very existence... Introduction...

In a compound where X = Br that is bromide compound produce transmissions that produce bands of the values approximately to these. Q7. The bond distance between C and N atoms will increase. This is due to reduced opposite charge potential between them that increase attraction. In C-N, C is partially negative while N is partially positive in charge because one electron is unbounded in C. Fe cations bond on the C side forming negative C-center hence the force of attraction is now distributed for both Fe and N. Cyanide ion is a strong enzyme inhibitor as it competitively binds with active enzyme site for the...

... Introduction to Chemistry: Analysis of Oxygen (O2) Introduction Oxygen is a chemical element that largely forms part of the atmospheric and is widely recognized with the sustenance of life and survival of organisms. It has a formula of O­2. As a chemical element, this substance has an atomic number of 8 and belongs to the chalcogen group on the periodic table; thus, making it build and possess certain significant characteristics for its operations such as being a highly reactive non-metallic element. Subsequently, oxygen is widely used as an oxidizing agent through its readiness to form compounds (in most cases oxides), with most of the atmospheric elements (Bauer, Birk & Pamela 145-149). Identification by mass sets this element... in...
