The experiment was done to reveal how workouts supplements like C4 can affect the development of humans. Other experiments like this one can also be used to show how some substances may affect the development of humans. In the experiment the independent variable was the amount of the C4 that was placed into each well in the experiment, and the dependent variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo solution…

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…

when the word chemistry comes appears. With the subject of chemistry, people usually think of cool experiments such as making toxic chemicals and blowing things up; however, writing plays a very vital part as a chemist. Dr. John Leyba, the chemistry and biochemistry department head and professor at the University of North Georgia (UNG), was able to give an insight of writing in the world of chemistry. Earning a Bachelor of Science in Truman State University and a Ph.D. in Nuclear Chemistry from…

Introduction: Many chemical compounds are broken down into two very distinct categories: acidic or basic. Acidic, based on the Bronsted-Lowry Theory, is defined as a proton (H+) donor. An equation exemplifying an acid dissolving in water is: HCl (g) H2O H+ (aq) + Cl- (aq) A base, based on the Bronsted-Lowry Theory, is defined as a proton (H+) acceptor. An equation exemplifying a base dissolving in water: NaOH (s) H2O Na+ (aq) + OH- (aq) Molarity, also known as the concentration…

Levofloxacin cocrystals were prepared by solvent evaporation method. The drug and co formers, stearic acid and sodium saccharin were physically mixed in varying ratios of 1:1, 1:3, 1:5, 1:7 and 1:1 and 2:1 respectively in a glass mortar and the mixtures were dissolved in ethanol as solvent for crystallization. The solvent evaporation was carried in rotary flash evaporator (Laborota 4000, Hiedolph) maintained at 40 ± 2ºC and speed of 30 rpm. The products obtained were dried in a desiccator and…

this experiment we will be able to better understand how the process of diffusion and osmosis works. My hypothesis is that diffusion will continue to occur throughout these various mixture of concentrations in the dialysis bags until equilibrium is reached. Once equilibrium is reached there should not be any net movement. Therefore, I predict that the bag with the higher concentration of sucrose will turn out to be hypertonic and while the lower levels of dialysis bags with sucrose will…

Chemicals Congo red (CR) an anionic dye (C32H22N6Na2O6S2 and Molar Mass as 696.7 gmol-1) used in the present work (Fig.1a) and zinc acetate dihydrate were purchased from LOBA Chemie Company, India. Methylene blue (MB) a cationic dye (C16H18N3SCl and Molar Mass of 319.85 gmol-1) as shown in Fig.1b, was purchased from Oxford laboratory reagent Co. Zinc acetate used for the preparation of nanoparticles ZnO and sodium hydroxide were purchased from Biotech laboratory chemicals company. Ethyl alcohol…

Marcel Duchamp | Fountain “All in all, the creative act is not performed by the artist alone; the spectator brings the work in contact with the external world by deciphering and interpreting its inner qualification ..” Do you know, which artist could have said this? That was a citation of Marcel Duchamp, one of the most important artists of the 20th century. In the next few minutes I will give you some informations about the person, who said this quite interesting words. Duchamp‘s life…

7.59 From the stress–strain data for poly(methyl methacrylate) shown in Figure 7.24, determine the modulus of elasticity and tensile strength at room temperature [20°C (68°F)], and compare these values with those given in Tables 7.1 and 7.2. Solution From Figure 7.24, the elastic modulus is the slope in the elastic linear region of the 20C curve, which is The value range cited in Table 7.1 is 2.24 to 3.24 GPa (325,000 to 470,000 psi). Thus, the plotted value is a little on the…

Introduction Enzymes, which speed up a chemical reaction without being consumed or changing the products of the reaction, are very important because they control the cellular activity of all living organisms. Enzymes are also described as being “catalysts”. In biological systems, specific enzymes catalyze particular cellular reactions. Each enzyme has a unique 3-D shape, and this shape determines which reaction it catalyzes. However, in order for a chemical reaction to move forward, an energy…
