This week's reflection assignment consists of one video. It features Mr. Larry Potterfield (founder, and CEO of Midway USA) as the presenter. The video is titled "Gunsmithing: How to properly polish the metal parts on a Remington 700". Mr. Potterfield begins his first video by stating the objective, polishing metal parts. In his hands, he holds the barrel of a Remington 700 series rifle. It appears as if the rifle has definitely seen some cleaner days, in my opinion. This is a skill every…

1. In our notes, we reviewed the Major mineral: Sodium. We know from news and health professionals, our intake of sodium is well over recommendations for our bodies need. List three specific changes you could make to your diet to decrease your sodium intake. • Eat more fresh fruit and vegetables since they are low in sodium. I have also learned that canned and frozen fruits are also low in sodium. • When buying frozen vegetables I have learned that reading the label will help you to…

the reference material (Figure 1.2) but we could just compare the results. General Solubility Guidelines of Ionic Compounds in Water SOLUBLE COMPOUNDS EXCEPTIONS Almost all sodium (Na+ ), potassium (K+), and ammonium (NH4+ ) salts All chlorides (Cl- ), bromides (Br- ), iodides (I-) Ag+ , Hg2+ , Pb2+ All fluorides (F- ) Mg2+ , Ca2+ , Sr2+ , Ba2+ ,Pb2+ All nitrates (NO3- ), chlorates (ClO3- ), perchlorates (ClO4-), and acetates (CH3COO- ) Acetates of Ag+ and Hg2+ are only moderately…

Laboratory Manual is a chart on suggested liquids and the inference if the compound is soluble [1]. When then checked the pH of the solution by using pH strip. The solution had a pH>7. Then we did an anion test and discovered the compound reacted with chloride by producing a white precipitate. The precipitate that formed was an insoluble solid because Cl of NaCl reacted with Ag of AgNO3, creating a Cl- ion above the aqueous solution [3], results on Table 2. Finally we used a cation flame…

The biology 151 lab groups at the University of North Dakota conducted an experiment to find out the effects of sodium chloride on the plants that are not naturally grown in salty soils. Wisconsin Fast Plants, which are naturally grown in low to no sodium chloride concentrated soils, were planted and grown in several different salt concentrations to discover whether the plants grew better or worse in given soil concentrations. After multiple measurements, the results came back that the plants do…

Out of many early photographic processes, I select the Anna Atkins Photographs of British Algae: Cyanotype Impressions, 1843 Cyanotype. I select this process because the color of this picture is very different to the others in the lecture making this photography stand out and get my attention. While I was doing my researches, I found out that the process to make this picture is not complicated, does not require a lot of materials, and needs a negative image which reminds me of the class activity…

and barium chloride. If a sulfate anion was present in the unknown solution, then the anion would combine with the barium and form the precipitate, BaSO4, and the chlorine ion would combine with the unknown’s cation. In this case a sulfate anion was present in the unknown so the sulfate combined with barium in the form of a precipitate, and the potassium combined with the chloride ion as an aqueous solution. The same fundamentals are used when testing for a chloride anion. If a chloride anion…

our environments so is that salt that was previously used to treat the roads (Gould, 2013). Roadside vegetation can become injured or die to due to the runoff from the treated pavements (Gould, 2013). The salt used for treated pavements is usually chloride-based and is applied to roadways, driveways, sidewalks, and highways to melt ice and snow to ensure safety for pedestrians as well as motorists (Gould, 2013). To improve traction de-icing salts can often be mixed with abrasives such as sand,…

Salts and molecules have different properties because salts are ionic compounds and molecules are covalent compounds. Justification: Salt is an ionic compound. An ionic compound is formed by ionic bonding between ions of opposite charge. Sodium Chloride and Potassium Bromide are both salts that have an ionic compound. Both elements have the properties of salts which include soluble in water, conductive, and a relatively high melting point. Molecules and Sugar molecules are covalent…

change in temperature of 8.5*C and a theoretical change in temperature of 1.03*C. The percent error for this additive was 8.1% error. My hypothesis was,If the freezing point depends on the number of ions in a substance, then the chemical aluminum chloride will have the greatest impact on the freezing point because it has the maximum amount of ions. My hypothesis was not supported because, NaCl is the additive that had the greatest impact on the freezing point because the concentration of the…
