Figure 1 Interpretation of the data Graph 1 indicates that as the dry mass of the water rocket increases, the maximum altitude it can reach when launched decreases. The R2 value, which indicates the strength of the correlation between two variables, where one indicates perfect correlation and zero indicates no correlation, in this graph is 0.989. Moreover, the correlation is negative, which can be seen from the coefficient of the X in the equation (-40.667x+ 30.02). For every gram the rocket’s mass increases the maximum height gets reduced by 0.0407 meters. This specifies that as the dry mass of the water rocket increases, the maximum height it can reach decreases.
The initial mass of the last potato was7.04g after it was placed in 0.6M Nacl solution for thirty minutes the mass of the potato decreases to 6.29g showing that water was moved out of the potato into the solution. In this lab we talked about the pH and fizzing of catalase activity. Chemical reaction is sped up by biological catalase known as enzymes. In cold temperature enzymes activities slows down. Enzymes denature in high temperature.
Activation energy is required to start a chemical reaction. Enzymes lower the activation energy needed for the reaction and cause the reaction to accelerate We buy the Hydrogen Peroxide solution form pharmacies and extract the catalysts from the potato. Filter paper has been dipped into the solution. The oxygen that has been produced from the reaction will form
Effect of the temperature on conversion (8 g/L catalyst loaded membrane, M=1) Conversion was increased by temperature in both of the BR and the CMR. However, conversion of CMR was higher than conversion of BR. In CMR, water, which occurred from the result of the reaction, was removed from the reaction medium. Therefore, reaction equilibrium shifted toward the products. Thermal mobility of the polymer chains increased with increasing temperature.
In doing so, we can deduct that the stomach acid is used to break down food to make it soluble for the blood to absorb. Starvation is when you prevent food from entering your body. If this happens, the stomach is producing the stomach acid but it is not doing its job, and then it just continues to buildup in stomach acid in the body. Due to the state of stomach acid, it can be absorbed in the blood and therefore affecting the pH. Looking at the results, addition of HCl in the water resulted in a decrease in the pH.
The peak position systematically shifts towards lower 2θ values with Na doping (shown in the Fig. 1a), which reveals the successful doping of Na ions into the host matrix. The average crystallite size of Pristine and Na doped CuO were calculated by measuring the full-width at the half-maximum of the most intense diffraction peak (-111) using Debye–scherrer equation, D =0.9λ/ β
It is, therefore, critical for a hydrogen sensor to have a wider measurement range (1–99% v/v H2) for safety applications than most common fuels. Hydrogen is the lightest of elements and the smallest molecule; it, therefore, has the greatest tendency to leak. REPORT ON: HYDROGEN SENSORS & EXTRACTING HYDROGEN FROM WASTEWATER Extraction of Hydrogen from Sewage Page 28 Hydrogen Measuring Principles Performance Sensors must have a broad operating range in air, nitrogen, and inert backgrounds (2–99% v/v) and good sensitivity well before the explosive limit (4% H2) in air backgrounds to meet National Fire
Higher rates of Rutuba fertilizer led to low exchangeable acidity while higher rates of NPK led to higher exchangeable acidity. Rutuba fertilizer application rates led to higher total carbon content than NPK application rates. Application of 1875 kg Rutuba/ha had significantly the highest carbon content. Application of 1875 kg Rutuba/ha had significantly higher content of Mn than all the other fertilizer regimes. The manganese content increased as the Rutuba rates increased.
They found that the factors that affected the volume of extracted orange oil were sodium chloride concentration, the extraction time, and the ratio between water and orange peels. From their result, they discovered that the most significant factor was the concentration of sodium chloride. Their result showed that 4% of sodium chloride concentration yielded the greatest volume of extracted orange oil because this is the optimum concentration that can increase the ionic strength of water. Hence, it can decrease the solubility of orange oil in the water most effectively. On the other hand, the total time taken to extract the maximum volume of orange oil was 2 hours and 30 minutes.
The results of this experiment highlight the dangerous effects of water pollution from indiscriminate use of detergents on plants. Thus, it is important that we use environment friendly detergents and governments start treating sewage/ polluted water before letting it into rivers and streams. The growth results have been depicted in the following graph: The average height of plants in each pot has been taken in centimetres and the growth was measured for 21 days. (VIII) CONCLUSION: The plants in Pots 4 and 5 did not sprout. The growth in Pot 0 was the highest as there was no detergent mixed in the water supplied to it.
