Discussion: For this week‚ we did the experiment under family of cereal which was about to investigate the effect of different alkaline solution on the quality of yellow wet noodles. There were four different formulations that we used. According to the table A in the procedure‚ it stated that for formulation 1‚ we were using Sodium Carbonate with sodium chloride as the alkaline salt solution while formulation 2 with Soda Ash with sodium chloride and formulation 3 with Potassium Carbonate with

Grades K-5 Pencil Electrolysis Introduction: The process by which we separate the elements hydrogen and oxygen from water is called electrolysis. The word "lysis" means to dissolve or break apart‚ so the word "electrolysis" literally means to break something apart (in this case water) using electricity. It is difficult to break up water into it’s elements lots of energy is needed to do that. Through a chemical means though‚ we can separate the compound of water into the elements that combine to

The reason that Sodium gives electrons when reacting with a substance such as Chloride instead of sharing electron in a reaction such as the Hydrogen and Oxygen forming water molecules can be found in the type of bond in each example reaction. Before I can identify the contrasting characteristics of each reaction‚ I must first acknowledge the reason atoms react with one another in the first place. Each element has a certain number of valence electrons‚ an example being Sodium having one valence electron

Drawing the Lewis Structure: Here are some simple guidelines for drawing correct Lewis Structures of covalent molecules (and also polyatomic ions). 1. Determine the Number of valence electrons in the Lewis Structure: One of the easiest ways to start drawing a Lewis Structure is to make a list of each atom in the structure and next to each atom record how many valence electrons it has and how many it needs to fill its valence shell. In covalent bonding the valence electrons in the molecule

completely transferred from one atom to another. Ionic Bonds have another name‚ Electrovalent bond. These bonds form from electrostatic attraction between opposite ions of a chemical compound. Ionic bonding is the bond that creates ionic compounds. During the bond‚ some atoms are more stable when they lose or gain electrons to form ions. Since the numbers of electrons don’t match the umber of protons‚ that is why they create a net charge. Galvanization is named after an Italian scientist named Luigi

Indeed‚ the war is within us. But then‚ I remember what I only need to do: to get the message across. Creativeness tells me that I need not to give the typical definition of missions. So I decided to divide the word mission into two words—miss and ion. Fortunately‚ these words turned out to be of great help. Miss‚ according to the Random House dictionary is a verb that means to fail to encounter‚ to meet or to catch. Missing an opportunity to witness is a big “no-no” in the mission field. Chances

Discussion A hydrate salt is composed of anions (negative ions) and cations (positive ions) which are surrounded by and weakly bonded water molecules. Each hydrate salt has a fixed number of water molecules associated with it‚ called waters of hydration or water of crystallization. When a salt holds waters of hydration‚ we

transportation of chloride ions between certain cells and the extracellular fluid. In mutation ∆F508‚ the proteins with deleted phenylalanine don’t insert into the membrane resulting in ion migration of chlorine being disrupted leading to the build-up of mucus. Chlorine’s negative charge disrupts the electrical potential of the cell causing certain molecules i.e. sodium to enter. The combination of NaCl is then excreted in vast amounts. This alters the balance of ions in the blood leading to abnormal

Dehydration Sci/241 Abbe Breiter-Fineberg 4/1/2012 Passing out‚ lethargy‚ constipation‚ dry mouth and even dry eyes are very few symptoms in the long list of signs to tell us that we are dehydrated. Being dehydrated is potentially very bad and if not taken care of a person can end up in the hospital or even dying. Many things can cause dehydration including drinking too much alcohol or simply not drinking enough water. Without ample amounts of water our bodies cannot function correctly‚

usually difficult to predict the products of decomposition reactions. The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction. Double-replacement reaction is a chemical change involving the exchange of ions between two compounds. These reactions usually take place between two ionic compounds in water solutions and are shown by production of precipitate. An example of a double displacement reaction occurs between sodium chloride and silver nitrate to form
