Silver chloride

The unknown compound was composed of small, white crystals as shown in picture 1. The compound was completely odorless, which was tested by simply smelling the compound. Picture 1 (Unknown Compound): The solubility test of the unknown compound determined that the compound was soluble in water (H2O). The other known salts that were tested that were also soluble were all of the sulfates and NaCl. These were the only salts tested, because before this experiment it was determined by the flame test…

In this experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any…

Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured. Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these…

with glucose and sucrose. Diluting 1 M of sodium chloride with water made six solutions. The six solutions ranging from 0M to 1M were prepared. These 6 solutions composed of 50 mL of solutions with different concentration of NaCl. The uses of concentrations of NaCl were 0M, 0.2M, 0.4M, 0.6M, 0.8M, and 1M. Then 6 equally sized and shaped cylinders of potato were obtained and weighed initially. Then these 6 potatoes were put inside of the sodium chloride solutions. After 45 minutes, the 6 potatoes…

Solutions should be the cations of cupric nitrate, ammonium nitrate, zinc nitrate, calcium nitrate, aluminum nitrate, silver nitrate, ferric nitrate, and plumbous nitrate. The other seven solutions should be the anions of sodium hydroxide, sodium carbonate, potassium sulfate, sodium iodide, sodium phosphate, sodium chloride, and sodium chromate. Divide students into groups of two. Provide a bin of paper towels for the students to empty their well plates. Students:…

China really only started coming to the Olympics in the early 90’s and wasn 't really known for anything athletic before then. In 2008 China ranked #1 overall in the Olympics finishing with 51 gold medals, 21 silver medals, and 28 bronze medals. China 's best sports at the Summer Olympics are badminton, diving, gymnastics, shooting, table tennis, and weightlifting. China is known for soaring in table tennis and has won 23 of 27 gold medals for table tennis in…

fit and just lay my chair back and was scowling. At this time Stef says “hey at least the radio still works”, and she hooked her iphone up to it and started playing relaxing music, which instantly flipped my mood. I think that her ability to see the silver lining in situations is one of the main reasons that I find it so enjoyable to be around…

Have you ever thought what if I had tried harder then I would have succeeded? Most likely you have and that is known as counterfactual thinking. Counterfactual thinking is the theory of what could have been. We tend to correlate our failures with counterfactual thinking. For example, if we had studied harder on that test and not gone out that night we might have gotten an A on the test not a B. We can also look at counterfactual thinking in a positive way and how that helps us in our lives. In…

Counterfactual thinking and living in imagination is another aspect of life that distracts adults and children from their realities. These individuals get captured in their thoughts of how life should be or how things should go. By adults and children carefully planning out their future’s and how certain things should happen, it causes misery when their “blueprint” does not go as planned. In Jeanette Winterson’s essay “The World and Other Places”, she introduces characters who live their lives…

When talking about older people in terms of physical activity it refers to peoples aged 65 or over. The guidelines for physical activity for older people are stated as . Adults aged 65 years and above should carry out moderate intensity exercise for around 150 minutes this exercise should be aerobic physical activity done every week, on the other hand elderly people could complete about 75 minutes of vigorous-intensity exercise or physical activity and this should also be aerobic and this can…
