Sodium

At first glance, all the substances may have been considered to be similar, as they are all white substances that are generally fine powder or small crystals. However, the lab revealed substances C: citric acid, D: sucrose, and H: benzoic acid to be covalent compounds, while the remaining substances to be all ionic. The previously stated covalent compounds all were found to have low relative melting points when heating them on a hot plate, but they had mixed results to their solubilities:…

Bast was immersed in 0.85% solution of Triton X-100 at 40 ⁰C for 10 min, followed by soaking in sodium hydroxide (NaOH) solution at varies concentrations (1, 2 4, 6 and 8%) at 100 ⁰C for 60 min. For enzymatic retting, the fiber was treated with chelating agent, enthylenediamine-tetraacetic acid, then immersed in 0.85% solution of Triton X-100 at…

pH effects because it’s a chemical. The pH is adds the bleach can behave builder stabilizes subs and foam. The soap that’s been put on your skin is made up of animals, and vegetable fat. As the acids they combine there sodium and to make soap, the salt is acid. Stand in for sodium as the different types of soap they made can be formu1a remains the same as the other soap that’s have been…

Effect of Sodium Bicarbonate on Photosynthesis Introduction Photosynthesis forms carbon dioxide into oxygen, making it an essential for life. (2) The purpose of doing this lab was to find out how sodium bicarbonate concentrations effected the rate of photosynthesis. (1) In photosynthesis, CO2 (carbon dioxide) is a reactant. CO2 is also produced by sodium bicarbonate. (3) This makes the addition of sodium bicarbonate to prompt the process of photosynthesis. This should cause the reaction to…

In this experiment, 25 g of solid sodium acetate trihydrate was added into a large beaker. The solid was then heat for 5 minutes, where liquid formed. 6.3 mL of water and a pinch of red dye was poured into the beaker while heated for 2 additional minutes. The solution was then cooled in an ice bath for 30 minutes. The solid-liquid product was then finally poured on a pinch of sodium acetate trihydrate crystal seeds to form ethanoic anhydride. This experiment was ultimately conducted in order to…

organizations been warning us about the dangers in sodium(table salt)? Today, i’m going to tell you about the health benefits and dangers in sodium(table salt). Also, i’m going to discuss the diseases you can get from too sodium. First, i’m going to tell you what sodium is. Sodium is a chemical element, it is a soft silver- white reactive metal of the alkali metal group; it is also the an electrolyte the body needs to regulate blood sugar. Sodium is extremely reactive, it never occurs in the…

African American women go through trial and error just to make sure their hair meet society standards. In the late 1940s, St. Paul, Minneota chemist and Jose Braquiel Calva invented the "chemical straightener", known as a hair relaxer today, has became very popular in the black communities over the years (Thompson 1). . Hair relaxers are designed to “glorify” and straighten the hair in a fast and easy process. Since the creation of hair relaxers, straight hair has been one of the many…

Mylah Ferland Animal Physiology Dr. Philip The Effect of Relative Humidity on Water Loss in Armadillidium vulgare Introduction We suspected that relative humidity had an effect on water loss in live Armadillidium vulgare, to test this we did an experiment with them in desiccators set with different relative humidity’s. Armadillidium vulgare (isopod) or pill bug need a habitat with a damp surface so that they do not dry out and die. To keep them from dying when we are not using them in…

As nurses we have many responsibilities and duty requirements. On a daily basis we treat, provide management, and assist our patients to returning to their baseline health status. Nurses promote healthy habits and most importantly educate our patients on disease prevention, infection control and proper health maintenance. Although, the only way to effectively do so falls on the nurse 's responsibility to remain up to date with current nursing practice and most importantly evidence-based practice…
