Worksheet #6: Combustion Reactions. We will focus on the combustion of hydrocarbons. Hydrocarbons react with oxygen to form carbon dioxide and water. methane (CH4) + oxygen Æ. ethane (C2H6) + oxygen Æ. propane (C3H8) + oxygen Æ. butane (C4H10) + oxygen Æ.
The following reaction represents the complete combustion of hexane, C6H14(l), at SATP. C6H14(l) + O2(g) → 6CO2(g) + 7H2O(l) ΔH° = –4163 kJ. (a) If 0.537 mol of carbon dioxide is produced in the reaction represented by the equation above, how much heat is released by the reaction?
Balance this chemical reaction, showing the combustion of hexane (C6H14) to produce water vapor, carbon dioxide, and carbon monoxide. Note the quantities of hexane and oxygen already specified in the equation: 30C6H14 +250O2 → H2O+CO2 +CO Next, calculate the proportions of fuel (hexane) to oxygen which will result in nocarbon monoxide being ...
3. The following reaction represents the complete combustion of hexane, C 6 H 14(l), at SATP. C 6 H 14(l) + 19 2 O 2(g) 6CO 2(g) + 7H 2 O (l) ΔH = –4163 kJ (a) If 0.537 mol of carbon dioxide is produced in the reaction represented by the equation above, how much heat is released by the reaction? [A: 373 kJ]
Calorimetry Worksheet. 1) If 0.315 moles of hexane (C6H14) is combusted in a bomb calorimeter containing 5.65 liters of water, calculate the molar heat of combustion of hexane if the water temperature rises 55.4 °C? The specific heat capacity of water is 4.184 J/g °C. H = ms T H = (5,650 grams H2O) (4.184 J/g °C)(55.4 °C) H = 1310 kJ.
i) Describe what this demonstration showed about complete combustion. ii) Describe and explain what would happen to the anhydrous copper sulfate and limewater if incomplete combustion occurred.
(a) Hexane (C 6 H 14) is a hydrocarbon which is a component of LPG (liquid petroleum gas), used as a fuel for heating. When burning fuels in boilers it is important to ensure complete combustion. (i) Give two reasons why boilers are designed to ensure complete combustion.
