Sodium (Na) Sodium has an atomic number of 11 and an atomic mass of about 23. It has a symbol on the periodic table of Na. It is a silvery-white metal found under the alkaline metals. Sodium is the “sixth most common element on earth and makes up about 2.6% of earth’s crust,” (RSC 1). It is usually found in compounds, including salt, sodium chloride (NaCl) or more commonly known as table salt. It is also used in baking soda, sodium bicarbonate (NaHCO3). Sodium is used to “de-ice roads in the winter and is used as a feedstock for the chemical industry,” (RSC 1). The most common use of sodium is adding it to food. It can be found on the back of food labels, measured in milligrams.

    Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.

  • Analysis Of Nickel And Dimed By Barbara Ehrenreich

    In a capitalist world, there are many opportunities to succeed, but an individual must be willing to work hard in order to ascend the social ladder. In Nickel and Dimed by Barbara Ehrenreich, she undergoes an experiment to see whether or not the average low-wage worker can get by in America. Ehrenreich claims that based on the wages that the low wage worker receives, he/she can not really get by and thus they don’t really have a way to get up out of poverty. However, the working poor do in fact have an opportunities to succeed, such as working up the corporate ladder from the bottom and saving money to build wealth, making Ehrenreich’s argument invalid.

    Brenda Umana Daniels 17 July 2014 English 3 Nickel and Dimed: On (Not) Getting by in America Important; that’s the first word that comes to mind after the reading of this novel. Ehrenreich’s writing in Nickel and Dimed: On (Not) Getting by in America is very powerful, brutally honest, and extremely engaging. She gained so much from her experiences, and we gained even more when reading them. Although she cheated on few occasions, she gives a clear insight into what poverty is, and how a life in a low pay, heavy workforce is not a life at all.

    New elements continue to be added to the periodic table as science knowledge increases. In January of 2016, a news article reported elements with atomic numbers 113, 115, 117 and 118 as approved by the International Union of Pure and Applied Chemistry. These elements completed the seventh row of the periodic table. Isdell shows the concept that chemistry continues to expand when Julie names an element in the Land of Science that did not previously exist, Wendelium with the atomic symbol Wd (Isdell, 442).

    My mom buys our groceries, and she has to eat a low sodium diet, so most of the stuff at my house is unsalted, lightly salted, or low sodium. Also my mother makes dinner, and she doesn’t cook with any salt. I usually eat with my family, so most of what I eat does not have much sodium content in it. The cultural influences on my diet might include the fact that portion sizes in our country are much larger than they probably should be. Also, there are less healthy options, and whole grains are not as prevalent.

    The formula for sodium acetate is NaC2H3O2, it is quite soluble in water, soluble in ether and slightly soluble in ethyl alcohol. While the chemical compound melts at 622.8℉, it does not have a boiling point for it will decompose. A hydrate is a chemical compound that forms when one or more water molecules are added to the molecules of another substance. Since sodium acetate is a trihydrate (NaC2H3O2·3H2O), it has three molecules of water for every molecule of sodium acetate and because of this, anhydrous sodium acetate quickly transitions into a trihydrate. This is due to sodium acetate being quite hygroscopic, meaning it readily absorbs moisture from the air.
