GRAVIMETRIC ANALYSIS OF A CHLORIDE SALT (2013) Report By: ____________ Lab Partner: ___________ Group: CHEM 1001 Tuesday AM‚ Group H Purpose: This lab was conducted in order to determine the content of chloride in an unknown salt‚ using gravimetric analysis. Theory: The salt chloride content is easy to find because it is slightly soluble‚ making it possible to turn it into a precipitate. A precipitate reaction can be done using silver

Review of Related Literature Calamondin or Clamansi‚ Citrofornella microcarpa‚ belong to the fruit tree family Rutaceae. The fruit of the Calamansi is a small‚ round lime‚ a little bigger than the size of a thumbnail‚ about 30 mm (an inch) in diameter. Similar to other citrus fruits‚ the calamansi is high in vitamin C‚ and the juice can be an excellent vitamin basis. The lively ingredient D-limonene destroys the wax coating of the insects’ respiratory system

the most abundant thing in the universe? Hydrogen is the answer! Now with a little bit more refining it will be. Good morning fellow students today I will be talking about hydrogen powered vehicles. Firstly‚ some terms need definition.Hydrogen- a colourless‚ odourless‚ flammable gas which is the lightest and simplest of all known elements.Vehicle- A device or structure for transporting persons or things. Secondly‚ now to explain the ways to use hydrogen as a fuel. The first way is called electrolysis

seem more suitable than hydrogen. The possibility of hydrogen as a fuel is ever increasing‚ with the advantages outweighing the disadvantages more every year. Car manufactures are already making cars that are hydrogen powered‚ although they are either prototypes or extremely limited production runs‚ but cars such as the Honda Clarity prove that hydrogen powered cars really are not a thing of the future‚ but a thing of the present. ABOVE: The Honda Clarity‚ the first hydrogen powered car to have a

aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen‚ where a higher concentration of inhibitor will yield less oxygen‚ resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed that less gas was

2.5.1. Processing Steps of Hydrogen Production from LPG Conventional process for producing hydrogen from light hydrocarbons involves the following process steps: • Feed preparation • Sulfur removal • Steam reforming • CO shift conversion • Autothermal reforming • Process gas cooling • Synthesis gas purification (PSA pressure swing absorption) [5] 2.5.1.1. Sulfur Removal LPG feed first passes through an ambient temperature sulfur adsorption vessel

As we are using enzymes and Hydrogen Peroxide we need to be extra careful‚ ensuring they don’t come into contact with our eyes‚ skin or clothes. Catalyse is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and Oxygen. We will be measuring the amount of Oxygen released from the Hydrogen Peroxide. In order to do this we will use a measuring cylinder. This piece of apparatus measures

well as the density was calculated. The same process was performed to calculate the density of an unknown substance. The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1. A metal sphere weighing 15.45 g is added to 21.27 mL of water in a graduated cylinder

Every step in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must
