Introduction: The purpose of the first experiment was to practice obtaining accurate and precise results by doing combustion analysis to find the amount of carbon dioxide and water released and the amount of fuel consumed. To identify the amount of carbon dioxide‚ water and burner consumed there were three equations used to find it. Equation 1 shows how much carbon dioxide was released. Mass of carbon dioxide = m2 - m1 Equation 1 was used as an experimental procedure created to help find out

calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average percentage is relatively close to the expected percentage of 20% thus

They then examined these samples through the SEM‚ XRD‚ and TGA to learn more about the properties and differences. The SnSp (powdered) species came from the SnSg (granular) synthesis during solvent exchange and the CO2 supercritical drying process. They found that the PAN hybrid was very much more mechanically stable than pure chalcogel‚ even though the as-made chalcogels adsorbed iodine more quickly

certain temperatures such as‚ 0°C‚ 22°C‚ and 95°C effect the concentration of the water and potato enzyme solution. In this graph‚ concentration is on the y-axis and time on the x-axis. In the legend‚ it displays which line represents which temperature. From the data shown in graph‚ it can be concluded that a lower a temperature such as‚ 0°C‚ will have a higher concentration and a higher temperature such as‚ 95°C‚ will have a lower concentration. Conclusions: The data recorded in the graph is related
