Silver chloride

Communication /6 Problem #2 Use the chart you just created to answer the following questions. a) Which substance would be the most corrosive? /1 Sample number 2 is the most basic and corrosive substance between the four samples. With its very high pH of 12, it can be predicted that sample number 2 is the oven cleaner that contains Sodium Hydroxide. Sodium Hydroxide (NaOH) is highly corrosive due to its elements; the presence of oxygen and an electrolyte (Sodium – Na) cause corrosion, the…

What is a foul weather gear and why you need it? Description: Foul weather gear is the must-have item when you set out for some adventurous activity. It must keep you warm and comfortable. There must not be any water penetration. Can you hear the winds howling and the rain blasting by in horizontal downpour? When the wind is sharp, the sky is grey and the spray is chilled as an ice, all you need is foul weather gear to sail comfortably in the winter weather. Sailing in winter becomes a pleasure…

is installed on the amino group using the corresponding acid chloride or acid anhydride. (3) Some acyl functions such as benzoyl, α-phenylcinnamoyl, and naphthaloyl are directly incorporated on the nucleobase using the corresponding anhydride (Watanabe and Fox, 1966; Bhat et al., 1989). Zhu et al. (2003) reported an improved synthesis of N-benzoylated nucleosides by reducing the amounts of chlorotrimethylsilane (TMSCl) and benzoyl chloride to nearly equivalent quantities. The major advantage of…

how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface being tested on which is a stove, the amount of water being used, the amount of grams used for the sodium chloride and the sucrose, and the time that is set for the water to heat up. What is controlled…

environment the student had, was water and sodium chloride. In this instance water was the model cell (what was in the dialysis tubing) and Sodium chloride was the surround environment (plastic cup). The initial weight of the model cell was 13.2g, but after sitting in the sodium chloride solution over night the cell lost water and only weighted 11.6g. Since the solution of the model cell- in this case water- left the cell and entered the surrounding Sodium Chloride it meant the cell had a…

Part one Make a 3 list of chemical safety hazards? The three chemical safety hazards are: Poison Toxic Corrosive Reactive Environmental hazards 2. What is Amalgam? Amalgam is mixture of metals of mercury with another metal and other metal. Almost all metal can be an amalgam with a form of mercury. 3. If you had to train someone on how to separate the mercury from the amalgam, what training would they need? WHY? If I had to train someone on how to separate the mercury…

Sodium alginate (SA) is a natural anionic polysaccharide obtained from sea weeds. It contains β-D-mannuronate (M) and α-L-glucuronate (G) residues linked by (1-4)- glycosidic linkages (Fig. 7.1) and arranged in homopolymeric blocks of each type and in heteropolymeric blocks [1]. It is a water soluble polysaccharide and has pKa values of 3.38 for the ‘M’ and 3.65 for ‘G’ units [2]. It can form complexes with positively charged polymers due to its anionic character. It is utilized as emulsifier,…

In this unit of my 9th grade Physical Science, we are learning and experiencing with labs. In this week's experiment, my class did the paper towel lab. Here, we tested the quality of three different paper towel brands, Viva, Up&Up, and Bounty. Each lab group was testing for a certain quality of each brand, such as strength and absorbency. Through different experiments, each lab group came to the conclusion that one paper towel brand had more strength or better absorbency than the other two. My…

reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of calcium chloride dihydrate is 2.8 grams. Materials: 2 Beakers (150 mL) Calcium chloride Sodium carbonate…

chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify a chloride, equal amounts of the unknown solution, 6M HNO3, and AgNO3 are mixed together and if a white precipitate is formed, the test is positive. To identify a sulfate, equal amounts of the unknown, 6M HCl, and BaCl2 are…
