Silver chloride

The chloride test resulted in no evidence of a white precipitate, which pushed the team to conduct the sulfate test. During the sulfate test, the solution became cloudy, the unknown substance did not completely dissolve, and there was evidence of a white precipitate…

Grilled Salmon There a variety of methods you can you to cook Salmon; however my best method is to grill it. The natural oils found in the Salmon help it to retain the moisture and also develops some crispiness on the outer side of the fish. Ingredients - 1 ½ pounds of salmon fillets - Lemon - Salt (to taste) - ¼ cup of olive oil - 1/3 cup of water - 1/3 cup of soy sauce - Garlic powder (to taste) Directions You just need a few easy steps to your ideal Grilled Salmon Prep time- 15 minutes Cook-…

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:…

chemicals, hormones, ions, and metabolites (book). The chemicals and agents used in this lab to modify the frog's heart rate and contraction are extrinsic factors. They are cold water, warm water, pilocarpine, histamine, epinephrine, calcium chloride, sodium chloride, hydrochloric acid, and potassium…

This Density of Copper lab was an experiment, which helped to show how to calculate the density of copper while comparing the results of the density of water. While doing this experiment we had to remember the density of water, which is 1g/cm3. However, before trying to find the density we needed to make sure we had the mass and volume. We were given two ways to help find the density of copper and a beaker. I had to first measure the mass of the copper by picking it up and gently placing it in…

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…

results showed that the bioluminescent bacteria was not affected by sodium chloride. They can actually survive in both fresh and saltwater. I discovered that the light intensity of the bacteria stayed between 0.02 and 0.07 lux. sodium chloride seemed to not affect the light intensity at all. In my background research I discovered that pollutants decrease light intensity of the bacteria. To learn more I use sodium chloride as my toxic pollutants and tested its effect on light intensity. Based…

Twenty kids one answer, who will figure it out. Everyone has been given the task to find the mystery mixture. At first they all had different clams. But now it is getting narrowed down. But there are some people that had different opinions. Everyone have been given water, a well tray, and a vial, along with other chemicals. I will explain how the class had gotten answer they did. And how they think it is right. The claim that will be explaining will be citric acid and baking soda. One of the…

The mixture of salt and sand is heterogenous and their physical properties can be used to separate it. To separate sand and NaCl it must be diluted with water then filtrated using filter paper. The residual water is full of dissolved NaCl since NaCl is water soluble. The NaCl can dissolve in water because of water’s emergent property; versatility as a solvent. Because water is polar, it can break apart other molecules until the molecules are bonded with water. To separate the soluble NaCl from…

The observed colour was orange, which fit the emission spectrum. Few specks of blue were observed, this might be due to the Bunsen burner not being completely cleaned or the sodium not being completely pure. The observed colours match those of the spectrum, and can be accepted as true. The observed colour for lithium was a dark red colour. Lithium’s emission spectrum consists of purple, blue, cyan and red. Few darker specks of blue were observed, possibly from the same substance that made the…
