Magnesium sulfate

“Classifying Chemical Reactions - Lab Report” I - Introduction - Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total…

relationship and Empirical formula of a Hydrate Purpose: The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for these labs to be performed. Only the registration…

solubility test of the unknown compound determined that the compound was soluble in water (H2O). The other known salts that were tested that were also soluble were all of the sulfates and NaCl. These were the only salts tested, because before this experiment it was determined by the flame test that the compound was a sulfate (explained later). This information means that the unknown compound is polar, because it is soluble in water. This is because H2O, the solvent, is polar, and the solute,…

Using your tongs, hold a small piece of magnesium in the flame. Do not look directly into the flame during this reaction. (1a) Pb (NO3)2 is a colorless solution. K2CrO4 is a yellow colored solution. Both solutions seemed to be odorless. When the K2CrO4 was added to the test tube that had the Pb…

Introduction The contamination of large bodies of water is becoming a greater problem across the world due to our rapidly increasing population. People commonly pollute these areas with their release of waste products and trash, and these contaminants can spread from small streams or lakes to oceans and complete ecosystems. The pollutants that are released into the water sources are often inorganic substances, and the dissolved forms of these compounds can become ionic cations and anions. An…

Name: Ifeolutembi Fashina Student Number: 13335535 Lab Partner’s Name: Ifeoma Agu Demonstrator: Maria Inorganic Chemistry Experiment 3: The Identification of Unknown Samples Objectives The experiments were carried out in order to identify 15 samples, through their physical and chemical properties. Theory A precipitation reaction is one which produces an insoluble salt as product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions…

physical exertion. It is a mix of amino acids (glutamine, arginine, L-valine, etc.), magnesium, selenium, and vitamin C. 2. Post-Sports Cocktail: Perfect for when the body goes into recovery mode. The formula includes amino acids (glutamine, arginine, and leucine), magnesium, selenium, and vitamin C. 3. Detox Cocktail: Like what its name suggests, this cocktail removes and counteracts toxins. It is a mix of magnesium, selenium, glutathione, calcium vitamin C, thiamine, and vitamin B. Travelers…

The reaction of soda ash (Na2CO3) with calcium sulfate in water is represented by the following chemical reaction: Na2CO3 + CaSO4 >>> CaCO3 + Na2SO4. Assuming that this reaction is complete and that there is 153 mg/l of CaSO4 initially present, what is the mass of soda ash that must be added to 1 liter of the water? How many grams of CaO are required to be the chemical equivalent of 246 g of Mg(HCO3)2? A complete reaction requires the number of CaSO4 to be equal to the number of moles…

1. Which one of the following would make the most suitable catalyst in the decomposition of hydrogen peroxide (H2O2)? A. Carbon dioxide (CO2) B. Sodium chloride (NaCl) C. Magnesium oxide (MgO) D. Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

safety measures in Maternity and Pediatric, such as turning the patient to their side, side rails are up and padded, and to reduce stimuli such as noise and light (Ricci). Therapeutic regimens are ordered to help prevent and treat seizures. “If magnesium sulfate fails to control seizures, then drugs such as diazepam should be administered” (Lawrence). If pharmacologic measures fail to help the patient, then delivery of the fetus is essential in both the mother and fetus’…
