Also‚ unlike other energy drinks‚ Monster Energy contained detectable traces of sodium chloride. The components of gingerale were also quite similar to the components found in other beverages. However‚ it contained no protein or lipids‚ unlike chocolate milk‚ and had a large amount of simple sugars‚ unlike Vitamin Water and Tea

laboratory techniques including proper mixing in an oxidation reaction‚ extraction‚ infrared spectroscopy‚ and gas chromatography. Reactants cyclohexanol and sodium hypochlorite (NaOCl) undergo a redox reaction and when combined with the catalyst acetic acid (HOAc) and solvent water (H2O)‚ form the product cyclohexanone along with sodium chloride (NaCl) and water. In the overall Figure 1: Cyclohexanol Reaction oxidation-reduction reaction‚ the secondary alcohol of cyclohexanol is oxidized to form

Bio Cement The project aims at attaining high durability of concrete and gaining high strength of cement. We plan to make use of bacterial species which can hydrolyze the enzyme Urease efficiently to produce microbial concrete. Such bacterial are known to produce calcium which is useful in giving strength to cement. We are working in 2 stages. Stage 1: Here we check the effect of bacterial solution on cement mortar and along with that we check the effectiveness of the bacterial solution

Experiment 8 Chemical Kinetics Abstract This experiment was done to determine the effects of the nature of the reactants‚ concentration‚ temperature‚ surface area and catalyst on the rate of chemical reactions. The nature of the reactants implies a difference if the reactants are aqueous or organic‚ acidic or basic or if they occur in the same phase or not. Acid-base reactions‚ formation of salts‚ and exchange of ions are fast reactions while reactions in which large molecules are formed

put it into the 100mL beaker‚ add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small paper cup. Then add the 25mL of distilled water to make the sodium carbonate solution. Mix the two solutions in the beaker and a precipitate of calcium carbonate will form instantly. Next‚ set up your filtration assembly. After the filtration assembly is ready‚ swirl the contents of the beaker to dislodge any precipitate

General Chemistry Laboratory 151 Chemiluminescence Introduction: The objective of tis experiment was to carry out systematic series of experiments in order to determine which chemicals and which ratios of chemicals produce the brightest light. Also‚ this experiment will determine which chemical produces the longest light. Chemiluminescence is the emission of light (luminescence)‚ as the result of a chemical reaction. There may also be limited emission of heat. This occurs because the

Lab: 5 Experiment:13 Pre-Lab The purpose of this experiment is to observe an equilibrium reaction counteracting changes to it’s system all in accordance to Le Chatelier’s principle. An equilibrium reaction can be pushed toward products or reactant based on changes in temperature or concentration. The reversibility of reaction will also be looked at. Pre-Lab questions 1. The concentrations of products and concentrations of reactants remain constant but both reactions
