Sodium hypochlorite

In the lab sodium hydrogen carbonate will react with hydrochloric acid. Then with the data gained from the lab, the use of stoichiometry is used to calculate the mass of the product, and compare the theoretical data to the actual data to calculate the percent error. When reacting the two compounds, it is placed over a heat source. The stoichiometry in the equation is to calculate the theoretical mass, or calculated mass, that is reacted from the compounds. The actual amount was the mass of the product

nylon were added. The nylon did not appear to be soluble in any of the three solutes. The last part of the experiment was the creation of slime. Slime is a cross-linked polymer that is formed from the reaction of poly(vinyl alcohol), PVA, with borax (sodium borate decahydrate) under aqueous conditions (1). Slime was made by combining 1 mL of Borax to 10mL of poly(vinyl alcohol) in a 30 mL beaker. The slime began to form immediately when stirred with a glass stirring rod and was transparent in color and

Per our discussion the best course of action that should be taken to remove the lite coating of Lead containing paint would be to remove it with heat. By using heat it will eliminate the lead and also eliminate the difficulty in capturing all of the debris created if we were to grind it off. Now I do have some requirements which we did discuss over the phone which I also included below. Respirator must be worn when burning these areas, also full Tyvek suit, gloves, and goggles also to cover

In experiment 2, temperature was the factor tested to see how it affected the rate of reactions. Tweaking the method for the first experiment, the sodium thiosulphate were in three different temperature; one was placed on a hotplate and heated, another in an ice bath and the last was room temperature. This showed how the temperature of the solution can be an important factor when investigating reaction rates. Concentration of the reactants affects reaction rate by increasing the rate when the concentration

We had to add a chunk of Sodium to a water bucket outside. We gently dropped it in, got away from it and observed the reaction. 3. We had to add 5 ml of Hydrochloric acid to a small beaker and swirl it. Then we added sodium hydroxide and had to check for heat and color change. 4. We had to add a small strip of copper to a beaker that held 3 ml of silver nitrate. We had to

blocks voltage-gated sodium ion channels. Describe the structure of a sodium ion. A sodium ion is essentially a sodium atom which had been oxidized, losing one electron and gaining a positive charge. Thus, the atomic structure of a sodium ion is an atom with 11 protons in its nucleus, but only 10 electrons in its orbitals, thus explaining its positive charge. Atomic Structure. (2015).

Baking Soda and Vinegar: Limiting Reactant Lab Background The limiting reactant of a chemical reaction is the substance that places an upper bound on the amount of product that the reaction can produce. The limiting reactant places this upper bound because the reaction must stop once all of the limiting reactant is consumed. If the relative amount of reactants is altered, then the limiting reactant may change accordingly. For example, a balanced chemical equation of a certain reaction specifies

In order for the Human Body to maintain balance within its internal environment or return systems to functioning within a normal range, it must manage a multitude of highly complex interactions in order to deal with external changes that are optimal for survival. The organs that help maintain homeostasis are the liver, the kidneys, and the brain through hypothalamus, the autonomic nervous system and the endocrine system. The main function of the liver is to metabolize toxic substance as well as stabilising

yellow in an acidic solution (Artxy, 2011). The solvolysis of tert-butyl chloride is revealed by the indicator change from blue to yellow as hydrogen halide is produced during the reaction (Mostafa, 2009). The solution is initially blue because of its Sodium Hydroxide (NaOH) content (alkaline), and the colour change results as aqueous chlorine removes a proton from the transition state, while the generated hydrogen ions neutralise the hydroxide ions of the NaOH, causing the change in the pH of the system

Chuck Wagon Cooking: Cooking For a Large Group Cooking without electricity is the type of cooking that some if not many of you have not experienced other than when camping overnight or when the electricity is out for a few days. Obviously, when the power goes out and the propane bottles run empty cooking becomes more difficult. Making Coffee We need to keep our priorities straight here so coffee first the old-fashioned way. Coffee is brewed using a handful of grounds to one cup of water. You would
