Hello, I am looking for someone to write an article on Properties of Gases. It needs to be at least 1750 words. When the water in the pipette bulb had been completely displaced by hydrogen, the pipette was removed in an inverted position, and a thumb was placed over its opening to keep any gaseous content from escaping. A match was lit, and a small portion of the pipette content was squeezed into the flame from a distance of about 1 cm. Observations were made, and the results were recorded. The wide-neck pipette bulb was marked with a marker pen on the outside into three equal parts. The marked pipette bulb was filled with water, inverted and was set onto the gas generation tube. When about two thirds of the bulb was occupied with the produced gas, the bulb was removed while in an inverted position. The pipette bulb was set with its mouth facing down into one of the wells of the 24-well plate for later use. The test tube was disassembled and was rinsed well with water. Preparation and test for oxygen gas Few pieces of Manganese metal were placed into a second test tube. Enough of 3% Hydrogen peroxide was added to fill the test tube almost to the top. A rubber stopper with plastic gas delivery tube through its center was inserted into the test tube, and the test tube was placed into a well of the 24-well plate. The test tube was wedged into a straight position by use of a paper tissue. The reaction was observed, and the observation was recorded. A comparison was made between the reaction in the first part of the experiment and the reaction in the second part of the experiment. Another wide-neck pipette bulb was completely filled with water. The pipette was inverted and was placed on the delivery tube of the test tube.
