Magnesium

hydrate, MgSO_4, may have been heated too long. This is a random error because when the hydrate has been heated too long, some of it could have reacted with the molecules in the atmosphere. As a result, the magnesium that was part of the anhydrous salt could have reacted with oxygen, thus forming magnesium oxide and losing…

constant mass of magnesium metal (0.100 g) and varying volumes of 2.00 M hydrochloric acid added from 2.00 mL to 7.00 mL in progressions of 1.00 mL which in total came out to be six distinctive chemical reactions. Group B used the consistent volume of 2.00 M hydrochloric acid (5.00 mL) and changed the mass of the magnesium metal used from 0.070 g to 0.170 g in growths of 0.020 g which resulted in a total of six different chemical reactions as well. The percent yield for magnesium, according to…

will discuss was a high alert drug called magnesium sulfate. From the start of my nursing school journey and all my other experiences in clinical, I knew this one was one of the most eye-opening experiences for me. This medication required q 1-hour assessments after continuous infusion was started, and observation for possible toxicity. Magnesium sulfate is a drug that is used to prevent convulsions in a preeclampsia patient, Lowdermilk (2016) found “magnesium sulfate is the drug of choice for…

Because the halide cannot be eliminated, the next best option is to minimize the amount of halide in the reaction. In this experiment, a small concentration of the halide is reacted with a high concentration of magnesium to ensure maximum contact between halides and magnesium. To do this, magnesium will be placed in the round bottom flask and then halides are slowly added. Another potential source of error is that Grignard reagents must be placed far away from water sources. If any water is…

Rationale I decided to turn this lesson into a flipped lesson as the topic on ionic bonding is something very microscopic and I feel it would help students to develop a more concrete understanding of an abstract topic. By recording the lecture which includes a step-by-step guide on drawing a dot-and-cross diagram, the weaker ones will be able to study at their pace and choose to pause or rewind should they not understand. This helps them to understand the concepts better, as opposed to going…

Epsom salt has a high content of magnesium, and this is the main reason why it is used to relieve aches and pains. However, besides being used in the case of aches and pains, Epsom salt is a great garden additive, recommended by a great number of expert gardeners. Most plants are being grown in soil, severely depleted in magnesium. Because of this, we as consumers can experience magnesium deficiency for eating foods poor in this mineral. Being a great source of minerals, Epsom salt can help…

The rate of respiration of yeast, using two saccharides and an amino acid, in combination with the cofactor of magnesium, was determined using respirometers. A positive control sample of yeast and water, and a negative control sample of glucose, sodium fluoride and yeast were also employed. After seventy five minutes, the sample containing glucose, magnesium and yeast showed a markedly higher production of CO2 than the other samples. This result supported the hypothesis that glucose is the…

Starting off with my intake of calories, I was below the daily recommended number of calories. This tells me that I eat below the number of calories I’m supposed to eat daily. Then my cholesterol was different on both days. On my first day, I was a little over the recommended amount, but my second day was over the recommended amount. Secondly, my protein intake was different from both days. The first time I was under the daily recommended amount, but my second day I was over the amount by a lot.…

INTRODUCTION: Indigestion is difficulty digesting food; it causes pain or discomfort in the stomach. Most commonly, people suffer from indigestion by overeating, drinking alcohol while eating, or eating greasy, fried or spicy foods. Acid in the stomach helps digest food and prevents infection. Mucus lines the stomach, bowel and oesophagus and acts as a barrier against the acid. If the layer of mucous gets damaged, the stomach acid can aggravate and cause inflammation to the stomach; this leads…

7. If during the experiment an air bubble leaked into the eudiometer tube while it was being inverted in the water bath than the measured volume of hydrogen gas would be off. Ultimately the measured volume of hydrogen gas would be too high because the gas being recorded would not only include hydrogen gas, but the air that leaked into the eudiometer as well. Because the volume of hydrogen gas would be too high the calculated molar volume of hydrogen would also be too high. This is because to…
