In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium

hydrated salt in order to determine the percentage of water inside of this hydrated salt. We heated up the salt in order to boil off the water‚ which allowed us to find the weight of the CuSO4 by itself. By comparing this final weight with the original weight and subtracting the difference‚ we were able to compile data about how much the weight of the hydrated salt decreased as the water gradually boiled away. In doing so‚ we were able to find the total weight of the water in the hydrated salt by subtracting

2 Part 1: In favor of: • Strengths- There is enough conclusive evidence that a reduced salt diet will help decrease future health risks. This shows that over time people that they studied that had a diet that contained less salt showed a decrease risk of developing cardiovascular disease. The fact that they have a few large companies on their side somewhat trying to reduce the amount of salt in their food works well to try and get others to follow. This shows that the companies that will

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

Love Across the Salt Desert K N Daruwla The story "Love Across the Salt Desert" is set in the village of Khavda‚ located in the Desert of Kutch‚ Gujarat‚ India. The author has used this backdrop to effectively symbolize the thirst that the two protagonists feel for one another--so the scorching sun of the desert becomes a metaphor for their parched lives which were looking for satiation. He also extends the drought prevailing in the land to be an expression of the same deprivation and with the

thirty-four‚ I became the matriarch of my family. The losses I encountered at the Bear River Migratory Bird Refuge as Great Salt Lake was rising helped me to face the losses within my family. (pp. 3-4). The book tells of the time before the death of the author’s‚ Terry William’s mother who was struggling with cancer. It also tells her story of the flooding of the Great Salt Lake‚ which coincided with that time‚ focusing in especially on its effects on the birds of the region. Together these stories

pictures of courtship wherein the patriarchy is still present‚ and an example of this patriarchal view can be seen in N.V.M Gonzales’ short story‚ where the courtship is evident between the male protagonist and Aida. In N.V.M. Gonzales’ “The Bread of Salt”‚ the male protagonist and the way he views his own masculinity and Aida’s femininity‚ as also seen in the story’s literary details and setting‚ reflect a patriarchal picture of courtship where the female is chased and objectified. An analysis of the

Carter Administration The first critical piece of foreign policy done by the Carter administration was the passing of the SALT II treaty later in the administration. It was the first treaty that successfully passed after these talks‚ and it stated‚ “Declaring their intention to undertake in the near future negotiations further to limit and further to reduce strategic offensive arms.” (The Government of the United States) The treaty was explicit in demanding the reduction of all aspects of the Soviet

Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The phenomenon being investigated in the lab was how the concentration gradient affects the rate of osmosis in a cell. Osmosis is the passive movement of water from and area of high concentration‚ temperature‚ and pressure. The concentration gradient is the difference

Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing
