Combustion Of Acetylene Lab Answers

Incomplete combustion is the reaction of an element or compound tit oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react completely, not all fuel is used. This may result in the formation of solid carbon a black residue. Procedure The lab was performed on 25 October 2012, the lab results obtained from Ms. Reynolds. Safety precautions were to not breath in the acetylene gas.

Essay Example on Acetylene Combustion Lab Report

Part A: Creating Acetylene Gas A 600 ml beaker was approximately half filled with water.

A test tube was completely filled with water. Test tube was covered with thumb and was turned aside down under water in the beaker. Tweezers were used to drop one piece of calcium carbide into the beaker and was quickly covered with the test tube to collect any gas produced. When the test tube was half full of gas, the test tube was lifted out of the water and the inverted test tube was set on the lab bench.

The procedure was repeated for 1/3 gas, 1/4 gas and 1/8 gas. Part B: Combustion of Acetylene Gas The test tube was placed upright in the test tube rack and a flaming splint was held at the mouth of the test tube. Observations were recorded. The procedure was repeated for remaining test tubes. Observations For the test tube with the ratio of acetylene to air is 1:1, a flame traveled down a test tube, a slight pop and black residue was left in test tube.

For the test tube the ratio of Acetylene to air is 1 a flame traveled down a test tube slower then better and there was a slight popping noise. For the test tube with the ratio of Acetylene to air is 1:3, a flame traveled down a test tube even slower, there was a slight popping noise and black residue . For the test tube with the ratio of Acetylene to air is 1:7, a flame traveled quickly down a test tube, popping noise and less black residue. Refer to table 1 for the specific lab results.

The other test tubes had black residue making them incomplete. Discussion The discussion between the ratio of the experiment does not agree with the balanced chemical equation because the ratio of the fuel and oxygen is not the same as the experiments equation. The ratio of acetylene to air is 1:and the balanced chemical equation is CACHE + 502 CHIC + OH. Therefore, the ratio for the chemical equation is 2:5 and does not match the ratio for the experiment.
