  • Gas-Solid Fluididization Experiment

    1004 Words  | 5 Pages

    A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operational limits, spillage of the beads, risk of head injury from bending over to change the beads in the apparatus or from the low bar, and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic

  • Iodine Clock Reaction

    1094 Words  | 5 Pages

    Title: The effect of concentration on reaction rates Introduction: - The iodine clock reaction involves mixing two clear solutions and producing a new clear solution. Then, after several seconds, the solution turns dark blue. This can be used to measure how fast a reaction occurs which is known as chemical kinetics. The time taken for the reaction mix to turn blue can be measured with a stopwatch. The reactions that form the basis for the iodine clock reaction are shown below. Equation 1: H2O2 +

  • Determination Of Chemical Formula Of Hydrate Lab Report

    Title : Determination of chemical formula of hydrate Aim To determine the chemical formula of hydrated Copper (II) sulphate, CuSO4 Research Background “When the chemical is heated the hydrate will convert to an anhydrous ionic compound (this means the water will leave it). The moles of H2O will be determined by assuming the amount of mass lost by heating is the mass of the evaporated H2O. The moles of the CuSO4 (the white substance after heating) can be calculated from the mass of the white crystals

  • Double Displacement Reaction Lab Report

    In cycle one, the double displacement reaction, Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) occurred, the result of the reaction was that the reaction mixture began to bubble with the copper filling dissolving and a vapor like substance leaving the reaction. Furthermore, when water was added, the color change, from brown to a blue color pigment. Then in Cycle two, another double displacement reaction occurred, Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq), which resulted in the reaction

  • 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

  • Lab Report Balanced Chemical Equation

    2042 Words  | 9 Pages

    actual yield is 0.38 grams. So if 0.38 is divided by 0.49 and multiplied by 100 then the percent yield for Zinc Sulfide would be 77.6%. When it comes to Sodium Chloride, the theoretical yield is 0.58 grams and the actual yield is 0.45 grams. So when 0.45 grams is divided by 0.58 grams and multiplied by 100, the percent yield would be 77.5% of Sodium chloride. The actual yield is directly taken from the mass of the products in the experiment while the theoretical yield is determined by using stoichiometric

  • 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

  • The Pros And Cons Of Clean Water

    822 Words  | 4 Pages

    Our topic is clean water and sanitation. The product is a tablet that turns any type of substance into clean substance. The water can be sea water, sewage water or any other dirty water. The tablet dissolves into the liquid and releases some of the chemicals to purify the water instantly. The filthiness in the substance will then sink to the bottom, where the other chemicals in the tablet will absorb all the dirt. In this way, the water is completely clean and fresh.

  • Morris Water Maze

    2025 Words  | 9 Pages

    BEHAVIOURAL PARAMETERS: Morris water maze Morris water maze consists of a large circular pool (100 cm in diameter, 35 cm in height), filled to a depth of 30 cm with water. Water was made opaque with titanium dioxide. The pool was divided arbitrarily, into four equal quadrants [12]. A clear Plexiglas platform with a diameter of 11cm was submerged 1cm below the water level. The platform was placed near the centre of a quadrant and rats were released into the water from 1 of the 3 remaining quadrants

    Recommended from the American College of Sport Science, adults need 150 minutes of exercise a week. We often eat too much for how little we move. If you are looking to lose weight you will need an average of 250 minute moderate-intensity, which only comes out to about 50 minutes a day for 5 days. Not bad, right? Now let's break it down. Lets look at your lifestyle. Do you work a desk job, or a job that is not physically demanding? If so, a sedentary person will only average 1,000-3,000 steps a day

  • Chemical Reaction Essay

    856 Words  | 4 Pages

    In the world around us there is five types of chemical reactions:synthesis reaction, decomposition reaction, single replacement reaction, double replacement, and combustion reactions. In modern day technology uses these reactions to produce a product or make products function. Single Replacement is a chemical reaction which occurs when one reactant switches for one ion of another reactant. Example 1: AB+C yields to AC+B In words, it is a reaction in which one element is substituted for another

  • Does Salt Affect The Floating Of A Raw Egg Essay

    676 Words  | 3 Pages

    How does salt effect the floating of a raw egg? Question: How does salt effect the floating of a raw egg? Hypothesis: If the water has more salt, then the egg will float higher, because salt makes the water's density higher by adding more mass to the water, so the egg would float higher in the water with more salt. Materials list- 1 500 ml cups 1 stop watch 1 raw eggs 70 ml of salt. 3.5 liters of water 1 measuring spoon 1 ruler Procedures: Put 350 ml of water in a

  • Rate Of Reaction Lab Report Essay

    837 Words  | 4 Pages

    Objective: I will be combining calcium carbonate with hydrochloric acid as a case study to measure the rate of chemical reaction. This gives us the equation CaCO3 + 2HCl  H2O + CaCl2 + CO2 Background Information: Several factors are already known which increase (or decrease) the rate of reaction. An increase in concentration of the acid allows for a greater number of hydrochloric acid molecules colliding into those of calcium carbonate. Although not every single particle would result in a successful
