3. Light a candle that is secured in a candle holder. Use tongs to hold the aluminum with sugar in it over the flame; record observations. Sodium Carbonate and Hydrochloric Acid 1. Add a small amount of sodium carbonate to a beaker.
Do this before it cools or water will travel backwards into your tube and contaminate your solid product. I 1 Collecting a liquid product: If you loosely wrap a damp paper towel around the upper-outer section of the boiling tube away from the flame, you might be able to condense a gaseous produCt into its liquid ·state. In addition to this you should cut a large piece of qualitative filter paper in half and then fold it and theri curl it inside the boiling tube near the rubber stopper. If a liquid forms, the finer paper will help absorb it and prevent it from falling back onto the solid being heated. Make sure the rubber stopper is securely in place since gas can easily leak out.
Aim To compare the reactivity of various metals by observing their reaction with hydrochloric acid Hypothesis That the all the metals will produce foam and a pop. Variables Independent – Magnesium, Aluminium, Zinc, Copper Dependent – Detergent, Hydrochloric Acid Controlled – Size of the metals, amount of detergent and hydrochloric acid Materials 2 M hydrochloric acid Detergent 10 x test tubes and test tube rack and 5 rubber stoppers 0.5 cm pieces of magnesium, aluminium, zinc and copper 2 cm pieces of magnesium, aluminium, zinc and copper Steel wool Ruler Timer Bench mat Matches and birthday candle Marking pen Safety Remember to wear safety glasses and protective gloves when you do this experiment. 2 M HCl is corrosive. Wash with plenty of water should you get any on your skin or in your eyes. Method Part 1 1 Clean the surface of the 0.5cm piece of magnesium with a piece of steel wool 2 Place the magnesium into a test tube 3 Add three drops of detergent to the test tube 4 Add 2 cm of hydrochloric acid to the test tube.
DO NOT PLACE YOUR FACE DIRECTLY ABOVE THE BEAKER. 8. When ALL of the water is gone, allow the beaker to return completely to room temperature on the table and measure its mass. NOTE: Never place a hot beaker directly on the table. Use the wire gauze as a barrier.
While conducting this laboratory experiment, be sure to use minimal amounts of each substance in order to create the habit of using only the amount necessary. This is a good habit to form so that product is not wasted and reduces the amount of product to dispose. Follow the steps below: 1. Pour 50 to 75 mL of water into a glass beaker and allow it to come to room temperature. 2.
4. Construct a simple distillation making sure all tools are dry and clean. The flask should be pre-weighed. Drying tube must be connected to a vacuum adapter by a hose. a. Drying tube- clear, plastic tube filled with drying agent 5.
Stirring carefully and observe the color of the hydrate until it changes to a consistent white color, then the Copper(II) Sulfate is dehydrated. 6. Turn off the burner, and wait to cool down the material. 7. Carefully determine the mass of the Copper(II) Sulfate, crucible, and lid.
When the gas comes out of the ground, it comes out wet. The first stage of the refining process involves on-site heating of the gas to 212 degrees to evaporate any non-methane hydrocarbons and fluids that are mixed into the gas. (Arthur, 2008) The condensate that is generated from this process is then vented into the atmosphere. The condensate often contains the same chemical additives that are added to the well during the fracking process, as well as volatile organic compounds that are naturally occurring in the ground where the gas is stored (Witter,
I also liked learning more about how atomic structure and electrical charge. 3. What did you like least? The least I liked about this unit was trying to learn all the equations and the solutions. Also when doing lab work I think that it needs to show more detail due to I think with that it would be more understanding.
First, heat the crucible without its lid, with a strong flame. 6. When the magnesium ribbon starts to burn, cover the crucible with its lid. 7. Using a pair of tongs, carefully raise the lid a little, at intervals.
