The s-block elements of the Periodic Table are those in which the last electron enters the outermost s-orbital. As the s-orbital can accommodate only two electrons, two groups (1 & 2) belong to the s-block of the Periodic Table. Group 1 of the Periodic Table consists of the elements: lithium, sodium, potassium, rubidium, cesium and […]
The concepts of eggshell qualityA good quality eggshell should contain, on average, 2. 2 grams of calcium in the form of calcium carbonate. Approximately 95% of a dry eggshell is calcium carbonate and has a typical mass of 5. 5 grams, although these values can differ depending on sources. The remaining mass is composed largely […]
Abstract: Calcium transport study of SF-9 lepidopteran cells and bull frog sympathetic ganglion cells The study investigated the intracellular calcium level and calcium efflux in SF-9 lepidopteran ovarian cells and bull-frog sympathetic ganglion cells using a calcium-sensitive fluorescence probe known as fura-2. It was found that the intracellular calcium levels were 58.2 and 44.7 nM […]
We’ve all seen it, lumpy milk poured from an outdated jug or lemon juice added to warm milk. What was once smooth, creamy milk becomes chunky, lumpy, and completely unappetizing. But curdled milk isn’t always a bad thing. Although it sometimes signifies spoilage, it can also be a method of producing more delicious food, like […]
Calcium is a mineral which is essential to the human body. In fact 1. 5% of the human body is made up of calcium, and not just the obvious uses such as bone and teeth formation but it is also a vital factor in many enzyme reactions, for example blood clotting. It also partakes in […]
Anlec Hi-Calcium Milk Executive Summary The case at hand is indicative of what will happen to a brand if the marketer failed to do diligent market segmentation. Clearly, the brand manager of Andec missed the opportunity with a product of such an enormous potential . He priced his brand 15% higher banking on its high […]
Tiles are especial things created by man to protect our house’s parts such as roofs, floors, walls, etc. Because it is useful to man, tiles lessen faster than ever since our population grows faster. Most of the Filipinos caught sick. This Is because dirt, bacteria, or maybe harmful Insects such as cockroaches, usually attracted to […]
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 and malleable are terms used to describe different properties of materials. Ductile means that a material can be easily formed into thin wires, while malleable means that it can be easily hammered into thin sheets. For example, a 20-gram piece of gold can be hammered into a sheet that will cover more than 6 […]
Isotopes, atoms with the same atomic number but different mass numbers, can be used in various ways such as radioactive tracing for thyroid and tumors. Radioisotopes, particularly gamma emitters with a short half life, are useful for detection without causing damage. Beta particle emitters are preferred over alpha particles because they penetrate more easily and […]
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 […]
