Insert the spoon with the burning sulfur in Bottle #3 and record your observations. When you used your torch lighter (who knows why you chose to...), you made a combustion reaction which formed the flame, and some of the Oxygen in the reaction reacted with the Sulfur … You just formed SO2, which is a poisonous gas. Health Hazards. Sulfur burns with a bright blue flame, producing sulfur dioxide gas. Then insert it in the empty bottle, and again record your observations. Sulfur reacts with oxygen in air to form Sulfur dioxide which is a major irritant and one of the causes for acid rain. Sulfur dioxide is a heavy, colourless, poisonous gas with a pungent, irritating odour familiar as the smell of a just-struck match. It burns with a pale blue flame. Inhalation of sulfur fumes causes irritation of the eyes, nose and respiratory track, which leads to headaches, dizziness and nausea 2.High levels of sulfur can burn the skin, and it can also cause pulmonary edema, a condition in which the lungs are filled up with fluids 2. Sulphur dioxide is soluble in water and has an unpleasant and suffocating smell of burnt matches. C. 8 0 grams. Answer. The sulfur reacted with the Oxygen in the air. Is burning of sulfur physical change? Elemental sulfur burning in oxygen gas. 0 moles of oxygen? At this level, the simpler sulfur dioxide is almost always used.) (You will find that the video calls this by an alternative name, sulfur(IV) oxide. B. The reaction between sulphur and oxygen is a chemical reaction in which, with gentle heating, sulphur burns in oxygen to produce colorless sulphur dioxide gas. Occurring in nature in volcanic gases and in solution in the waters of some warm springs, sulfur dioxide usually is prepared industrially by the burning in air or oxygen of sulfur or such compounds of sulfur as iron pyrite or copper pyrite. See clip K004 2148 for a sample of sulfur and a jar of its oxide side by side. The equation for this reaction is S + O2 --> SO2. Flue gas always (almost) contains substantial water vapor (hydrogen in the combustibles combines with oxygen in the combustion air to form H2O). What weight of S O 2 can be made by burning sulphur in 5. 6 4 0 grams. When finished, extinguish the burning sulfur in the beaker of water provided in the hood. Test 4: Combustion of iron Sulfur in a gaseous state mixes with oxygen to form sulfur dioxide, which is hazardous 2. D. 3 2 0 grams. Sulfur burns with a tiny blue flame in air, but a much brighter blue flame in oxygen. Burning Sulfur Compounds Sulfur compounds such as hydrogen sulfide (H2S), methyl mercaptan (CH4S) and sulfur (S) burn in the presence of oxygen to produce sulfur oxides (SO2 and SO3) in the flue gas. Sulfur. Sulphur and oxygen react to form either sulfur dioxide or sulfur trioxide, depending on reaction conditions. 1 6 0 grams. S + O 2 SO 2 The sulfur will first melt, then burn with an almost invisible blue flame. Sulfur dioxide gas is produced. About 32*g. This problem uses your understanding of equivalent mass. A.
