Masses of Steel Wool Before and After Burning Analysis/Conclusion: The purpose of this lab was to determine what changes are anticipated when a piece of steel wool burns. The hypothesis of this lab was the following statement; if a piece of steel wool is prodded with a charged 9- volt battery, then the steel wool will catch fire since a full circuit will be made Weigh an egg sized piece of steel wool. Carefully place the steel wool into the beaker and allow the chemical change to fully react. To be sure it is completed, carefully swirl the chemicals and observe. Measure and record the total mass of the products and containers using the same balance you used before. Part B: Weigh a 125-mL flask Burning Steel Wool. Description: This is an excellent phenomenon to discuss chemical reactions and the conservation of mass. Steel wool is burned leading to an increase in mass. When doing this in class show the students the burning steel wool to begin with and have them predict the change in mass. Most students believe the mass will either. We burned steel wool on a balance and noticed that the mass of the burning steel wool increased. The extra mass is from the iron oxide which is the result of the experiment. The air from the surrounding becomes apart of the experiment and weighs the steel wool down

Record mass of steel wool /evaporating dish after burning steel wool. Calculate change in mass. Record change in mass on class data table
  3. Usually, steel wool is made through the process of broaching: a thick steel wire is drawn through a toothed die, producing very thin steel shavings which are then collected and formed into the steel wool. Similar to sandpaper, steel wool is available in many different grades, ranging from very coarse (5# or greater) to very fine (000# or less)

Chris Sarns: False. West is deceptively equating the chain reaction that happens when steel wool burns to the iron spheres he created with his blowtorch that burns at 3,100°F (1,704°C). Furthermore, burning steel wool does not create iron microspheres. Instead, it creates iron oxide (rust) Station 2: Only small amounts of baking soda and vinegar are needed. The teacher may need to refresh the cup with vinegar several times throughout the lab time. Station 3: Burn one match in advance of the lab. Be sure to tell students that they are NOT burning the fresh match. Station 4: Only a small amount of steel wool and vinegar is needed AP Physics 1: Angular Momentum. This is the last topic students need before the AP Physics 1 exam. Students built the model using a Pivot Interactives activity where a marble is fired at a block. One of the questions I asked is whether the distance between the block's center of mass and the point where the marble strikes has any impact on whether the momentum of the block-marble system is.

Using the elements chlorine, calcium and phosphorous: (a) Select elements that will form an Oxide whose aqueous solution has a pH less than 7 2 Keep this answer! Since the moles of FeCl 3 based on moles of Cl 2 is the smaller answer, Cl 2 is the limiting reactant. Iron metal is therefore in excess amount, so there will be some Fe left over as unreacted excess. Note that we might have reasonably assumed that iron metal was the limiting reactant since it was presen The answer is yes if we can find a 2 or a 1. At this point you can do the teacher demonstration Another quick demonstration that also illustrates the different activities of metals is to burn a piece of magnesium ribbon, a sample of steel wool, and a copper strip or sheet using either
