The Effect of Alkaseltzer Tablets on the Boiling Point of Water Zackary Zambrano Chemistry Honors Mrs.Gregor Period-3 10/5/16 Introduction Statement of Purpose: The purpose of this experiment is to see whether or not alkaseltzer tablets have an effect on the boiling point of 100 mL of water. The control is just water, the variable groups are 100 mL of water with one tablet, and 100 mL of water with two tablets. “What exactly is boiling? The technical definition is what occurs when the vapor pressure of a liquid is greater than or equal to the atmospheric pressure.”(Lopez,k) Simply put water, boils when enough energy is released to cause bubbles and then turn to vapor. When water begins to boil, the water will continue to boil at
Exercise 1 1. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). Using your results from Data Table 1 as a guide, how would you test this material for the presence of sodium bicarbonate? B BoldI ItalicsU Underline Bulleted list Numbered list Superscript Subscript33 Words If I had a household product labeled sodium bicarbonate, I would add an acidic substance and expect bubble to be created. As we know acid reacts with bubbles when combined with sodium bicarbonate.
Serum sodium concentrations must be maintained between 130-145 mEq/mL. At levels below 130 mEq (hyponatremia), the CNS becomes swollen with water; cerebral edema leads to seizure, coma and death if not corrected. At levels above 145 mEq (hypernatremia), nervous system function is disrupted along with cardiac and renal functions. To avoid these extremes, the body has developed an entire hormonal axis devoted exclusively to sodium homeostasis. The kidney is the primary organ dedicated to sodium homeostasis; in most scenarios this means sodium retention.
1. Magnesium is an alkaline earth metal with an atomic number of 12 and an atomic mass of 24.305. It is part of the second group of elements on the periodic table located on the far left side of the periodic table. *CAUTION* Magnesium is a flammable metal! The equation for the reaction that is going to happen is: Magnesium + Hydrochloric Acid —> Magnesium chloride + Hydrogen Mg (s) + 2 HCl (aq) --> MgCl 2 (aq) + H 2 (g) This reaction is an Oxidation-reduction.
To understand this lab completely, it is important to know the concepts limiting and excess reactant. A limiting reactant is the reactant that limits the amount of product that can be produced in a reaction. An excess reactant is the opposite, or the reactant that remains after a chemical reaction is performed and the limiting reactant runs out (Stoichiometry: Limiting). The stoichiometry calculations determining what should happen can be found in the calculations section. The solid should form calcium carbonate.
This can help to prevent ulcers from forming or assist in their healing process. By decreasing the amount of acid, they can also help to reduce acid reflux-related symptoms such as heartburn. They are called ‘proton pump inhibitors’ because they work by blocking (inhibiting) a chemical system called the hydrogen-potassium adenosine triphosphatase enzyme system (otherwise known as ‘proton
Sodium picosulphate: An effective laxative as colorectal cleanser in colonoscopy preparation Introduction Colonoscopy is a powerful diagnostic tool against several conditions such as inflammatory bowel disease, colonic polyps, and colon cancers Bhandari P, Inadequate bowel cleansing is associated with numerous negative consequences. ( Park JB) The important barriers for the failure of colonoscopy include patient refusal to undergo colonoscopy and inadequate bowel cleansing. In the both the cases, patients unwillingness or intolerance to the preparation are important causes for the failure (Love J) . Patients prefer regimen that has better taste, low side-effects, and having manageable fluid intake (Bhandari P)). Sodium picosulphate may be preferred
Dichloro acetate (also known as DCA) has been predicted by many scientists to be the potential alternative cure for cancer since it was found that it killed the human cancer cells in a rat. However some scientists are not sure yet as to whether the treatment is the best solution because the human being studies have not been completed yet. Some scientists are against it because of its harmful side effects such as nerve functions. DCA is the said to be an acid, an analogue of acetic acid in which the three hydrogen atoms of the methyl group have been replaced by the chlorine group (2). DCA attacks the cancer cells and make their energy throughout the main body of the cell.
Because of limitless industrial importance of PUs, hence need to study diisocyanate chemistry briefly and understand the properties and their reactivity. Mainly the isocynates are highly reactive and allow to forming urethane groups without any by-products formation. This isocyanates contains two or more –NCO functional groups for one molecule is called as diisocyanes or polyisocyanate respectively. The industrial important monoisocyanate compound is methyl isocyanate (MIC), majorly used to manufacturing of pesticides but this isocyanate is extremely hazardous which is responsible to Bhopal disaster, in 1984. All diisocyanate are liquids or solids in the nature and highly reactive, it undergo reaction across the double bond C=N of the –NCO group.
This includes toothpaste made for smokers. High fluoride concentrations can not only remove the oxide layer on the implants, removing the anti-corrosive surface. Some fluorides, like stannous fluoride, can be rough on the implants, and might scratch the surface. As with natural teeth, patients with implants should use soft-headed toothbrushes; manual, electric, or sonic brushes are all acceptable options. Flossing should be done with unwaxed or implant floss to get the maximum cleaning while minimizing tissue damage.
Using two foam cups as a calorimeter is sufficient, although far from perfect. Using a bomb calorimeter would be much more accurate. Even calculating the calorimeter constant through experiment and taking this into account, this was still a large source of error. EXTENSION OF WORK: The article published by the Minnesota Pollution Agency, describes how salting the roads negatively impacts the environment. The article states that sodium chloride erodes the driving surface and the metal on vehicles.
The cancer cells are anaerobic and they cannot survive in the presence of oxygen. According to many health experts, cancer cells don’t use oxygen to survive. They survive on fermented sugar. This is why this natural and effective remedy contains maple syrup. This ingredient allows the sodium bicarbonate to enter the cancer cells and destroy them with a high dose of alkalinity.
It is very soluble because the smaller the chain of the molecules are then the energy will be required in small quantities however if the chain is long then it will need more energy so that means that the longer chain will have a slow reaction. It does not have a color and it does not cause fires to happen. It may burn the skin because it is a corrosive substance which is why you should wear gloves when you are handling it. If you swallow the hydrogen chloride then it can be dangerous because it is a toxic substance The bonding in hydrogen chloride is called covalent bonding because nonmetals and metals have the capability to react
The Sometimes Deadly Chlorine Chlorine is a yellowish-green poisonous gas with a very unpleasant and strong odor. (Appelman 516) It ranges from being used to kill in World War 1, to being used combined with sodium to make table salt. It can be a very dangerous element, but yet used for so many good things. Chlorine has a ton of history, multiple uses, and an interesting atomic structure. Chlorine combines with almost every single element, so it cannot be found in nature alone.
Fluoride is a naturally occurring substance that is released from rocks into the soil, air, and water. All water contains some fluoride, although the amount of fluoride that is necessary to prevent tooth decay is a set amount. Some water can contain too much, and some water can contain too little fluoride for the added benefit to protecting tooth structure. Community fluoridation sets the proper amount necessary in the communities water for optimal results and benefits of the fluoride. Fluoride works by strengthening and rebuilding tooth enamel and protecting the tooth from acids that are put into the mouth while eating and drinking.
