Reductionism- Reducing complex systems to simpler components that are more manageable to study. Cells- The lowest level of structure capable of performing all the activities of life, all organisms are composed of cells which are the basic units of structure and function. The cell theory- The ability of cells to divide to form new cells […]
This investigation is to find out what the concentration is of copper (II) sulphate that brings full denaturation of egg albumen. I can find this out by decreasing the concentration of CuSO4 using the serial dilution method to up the diluted state that no longer gets fully denatured. Background Information Egg albumen is a protein […]
The rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the ensuing metal solutions are tested and the merchandises of the reaction between Ca and H2O is discovered. The tried elements are sodium. Li. K and Ca and each of them were placed in […]
Ductile means it can be drawn into thin wires. Malleable means capable of being hammered into thin sheets. A piece of gold weighing only 20 grams can be hammered into a sheet that will cover more than 6 square meters. The sheet will be only 0. 00025 centimeters thick. Gold is also very soft; it […]
Chemistry Revision 831 Isotopes – atoms with the same atomic number, but different mass numbers 1311 – radioactive tracer for thyroid. Etc for tumors. Radioisotopes – gamma emitters & short half life – long enough to detect, but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they […]
Why Do Atoms React? Google Search 1. What is an atom? An atom is the basic unit of a chemical element. 2. What is an element? An element is a substance that is made entirely from one type of atom. 3. What makes an atom unstable (reactive)? The binding energy not being strong enough makes […]
A metal consists of a lattice of positive ions surrounded by a ‘sea’ of mobile ideological valence electrons. Metallic bonding is the electrostatic attraction between the ideological electrons and the positive ions in the metallic lattice. Properties of metals: Property Explanation Relatively high density The particles are very close together. This is because of high […]
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism, and biological The angles between bonds that an atom forms depend only weakly on the rest of the molecule, I. E. They can be understood as […]
This page explains what electronegative Is, and how and why it varies around the Periodic Table. It looks at the way that electronegative differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegative in an organic chemistry context, you will find a link at […]
Metals are the least electronegative of the elements. The Palling electromagnetisms for the elements are often Included as a part of the chart of the elements. An Important application of electronegative is in the prediction of the polarity of a chemical bond. Because hydrogen has an electronegative of 2. 1 and chlorine has an electronegative […]
Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to […]
Procedure: Obtain 8.5 mL of isoamyl alcohol and 15. 0 mL of acetic acid in a 100-mL round-bottomed flask. Add dropwise 5 mL of concentrated sulfuric acid with boiling chips and reflux for one hour. At the end of the reflux cool the round-bottomed flask in a cold water bath. Pour the contents of the […]
The Periodic Table of Elements is used as a way of displaying all the known chemical elements; it is accepted and used all over the world. The periodic table’s layout is very well structured; it consists of vertical rows called groups and horizontal rows called periods. It is one of the most important resources in […]
In the modern age, the use of plastics has caused a heated discussion amongst many parties. Politicians, environmentalists, the media, corporations, the general public etc. have argued for and against the use of plastics. This assignment will look into the importance of plastics in our society and the damage that it causes. The first type […]
In this experiment, the stereochemistry of 2,3-dibromo-3-phenylpropanoic was found to determine syn or anti addition of bromines. The melting point was 199-203°C and the NMR J values angle is at 167 which both prove the erythro-2,3-dibromo-3-phenylpropanoic. Determination of the Stereochemistry of 2,3-dibromo-3-phenylpropanoic acid. An addition of bromine was added to trans-cinnamic acid and it is […]
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 […]
Engineering Materials Week 2-interactivity What is the difference between crystal structure and crystal system? A crystal structure is described by both the geometry and atomic arrangements within cell, whereas a crystal system is described only In terms of the cell geometry. For cubic crystals, as values of the planar Indices h, k, and I Increase, […]
