Bunsen burner

the seaweed up on the tin lid supported on a tripod and begin heating with a strong Bunsen flame. It may have to be added a portion at a time during the heating, given the quantity to be reduced to ash. When all has been turned to ash, about a dessertspoonful of residue will remain. During the experiment we piled the seaweed into a tin container and placed it on top of a tri-pod which was placed over a Bunsen burner allowing the seaweed to burn and inevitably turn into ash so the extracting of…

that forms the compound, magnesium oxide. This reaction occurs due to the heat that provides energy to activate the reaction. A blinding white flame will burn as the reaction occurs. In this lab, magnesium is burned in an open crucible over a Bunsen burner several times until the magnesium ceases to burn. This process allows for the magnesium to completely react with the oxygen found in the open air, forming the chemical compound magnesium oxide. However, our lab did not provide us with the…

The clay triangle does not heat up, keeping the ring stand from getting hot. Turn on gas, and close the windows of the bunsen burner. It will not light with the windows open. Use a striker to light the bunsen burner. This is our only way to light the bunsen burner. Open the windows and let the baking soda cook for thirty three minutes. The decomposition of baking soda will not occur immediately. Let the crucible and its contents cool…

In the field of Microbiology, it is essential that the microorganisms being examined are seen clearly and distinctly under the microscope. Most specimen thrive in aqueous environments, therefore they are translucent and when mounted on a microscope the light passes through them making it impossible to see the specimen. Equally as important as this is that the viewer is aware of what type pf bacteria is being utilized. Both of these criteria in a lab are met with the use of a staining procedure…

Introduction The Objective was to determine the mass percent composition of the mixture using a chemical reaction and stoichiometry mixture Na2CO3 and NaHCO3. To do the lab by using the constant mass. Constant mass is a quantitative chemistry technique where a single chemical species or group reactants is heated with constant weighing until the mass does not change. After heated the Na2HCO3 will undergo a decomposition and Na2CO3 will not undergo reaction. The balanced equation is…

include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to be cautious when removing the beaker because it can be hot, so we have to be patient in letting it cool off. Additionally, not only do we have to be careful around the bunsen burner for being an open flame; however, some unknowns in this experiment are…

In the past there was no knowledge of what natural gas is, it was a mystery to man. Occasionally, gas would escaping from under the earth’s crust and when a lightning strike reached the gas, it would ignite the natural gas, creating a fire (Natural Gas.org). This was puzzling to early civilizations, which lead to myths and superstitions (Natural Gas.org). In ancient Greece on Mount Parnassus around 1000 B.C., a goat herdsman stumbled across a “burning spring” rising from a fissure in a rock…

Variables Likely impact upon the investigation How the variable will be changed/measured/controlled Independent variable Mass of Baking Soda (grams) Changing the mass of baking soda will impact the volume of gas is produced. The higher the mass, the more gas will be produced, and vice-versa. This will happen as the results of the decomposition of baking soda will be directly proportional to the mass of the baking soda. The independent variable will be altered by changing the amount of baking…

balance, bunsen burner, iron ring, crucible tong, clay triangle, wire gauze, retort stand, 1. Individuals should wear goggles on and tied hair back before the experiment started. 2. The mass of an empty crucible cover was measured. 3. Approximately 2.00g of copper (II) sulfate hydrate samples was taken out and put into the crucible. 4. The mass of the crucible cover and copper (II) sulfate hydrate samples was measured. 5. The heating apparatus were set up as instructed, such as bunsen burner,…

formula of the compound. Techniques used: In this experiment, different techniques will be used to collect the required data, such as taking the mass of the hydrate sample on a digital balance, assembling a ring stand, properly setting up a Bunsen burner and safely using it to heat the hydrate sample, properly setting up a…
