    Long-Chain Polyunsaturated Fatty Acids: The Case for and Against the Supplementation of Infant Formula. [Student Name] [Institution Affiliation] Long –chain polyunsaturated (LPS) acids are derived from two fatty acids known as, linolenic acid and alpha-linolenic acids found in plant based foods such as flaxseed. Through various biochemical pathways the LPS are used to synthesis eicosapentaenoic acid (EPA) and docosahexaeconoic acid (DHA). The conversation of ALA to DHA and EPA is very ineffective

    titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due

    oxygen in extreme cases it could cause death. It could react with other chemicals causing more sickness. If you consume nitrate then you could just get small stomach flu, but when pregnant, or a baby it could cause much worse because your stomach acids are different.

  • Catalase Experiment

    1443 Words  | 6 Pages

    The aim of the investigation was to determine the effect of pH on the rate at which catalase decomposes hydrogen peroxide and consequently answer the researchable question “How does pH influence cells and consequently an organism”. The hypothesis, “As the pH deviates from 7 the initial rate of oxygen production will decrease” is supported by the results. The trend displayed in Figure 3 is, as the pH deviates from 7 the initial rate of reaction decreases. Figure 3 shows that the rate of reaction (%O2/s)

  • Bromocresol Green Equilibrium System Lab Report

    547 Words  | 3 Pages

    The objective of the Bromocresol Green Equilibrium System Lab was to determine if the equilibrium constant, K, was a true constant at constant temperature. To determine this, the value of the constant was found at different concentrations of HIn, HIn-, and at varying pH, which was used to determine the concentration of H+. K was found using the equation K= [HIn]/([In-][H+]). In order to be a true constant, none of the values of K found should differ from the average by more than two standard deviations

  • Freezing Point Depression Experiment

    912 Words  | 4 Pages

    Discussion: In this experiment, freezing point depression was used to determine the molar mass of three unknown solids. First, the freezing point of the mixture of ice and water was determined, as freezing occurs when both the solid and liquid phases pre-present together. The temperature when the ice and water mixture reached equilibrium was recorded. Then, the solution of the unknown solids was prepared and its freezing point was determined. Then the equation of molarity allowed the experimenters

    it causes water vapour to condense forming small water droplets. We breathe in oxygen and some nitrogen which is essential for life. We exhale carbon dioxide that can be tested for limewater because carbon dioxide dissolves in water to form carbonic acid (H2 C03). Glucose is a reactant of respiration. The glucose in your blood comes from carbohydrates in your food. Carbohydrates include sugar and starchy foods like: bread, pasta and rice.

  • Fe2 + Lab Report

    482 Words  | 2 Pages

    If there is a change in concentration, temperature, volume, or total pressure the equilibrium will change in order to react to the change. This concept was shwon throughout the experiment by the adding of new reagents and temperature changes. This was shown by the mixing of NH4NCS and Fe(NO3)3. The two chemicals together produced a dark red FeNCS2+. Since the solution became a dark red, the concentration of FeNCS2+ had increased. The darker solution means that the products are more favored at equilibrium

  • Average Concentration Lab Report

    597 Words  | 3 Pages

    The average concentration of my unknown Al3+ solution (#41) was 0.02372 0.00016 mol/L. My %RSD was 0.67%, which I would say is very good. This means my precision relative to my average was very good. When calculating the mass of the precipitate, my Trial #1 and #2 were both 0.271X, with Trial #3 being 0.27XX. Having Trial #1 and #2 being only 1 decimal place different from each other was very surprising to me, and indicated high precision. This led to a low standard deviation and a low %RSD. I think
