Acetylene burns in air to produce carbon dioxide and water: C2H2(g) + 5/2O2(g) → 2CO2(g) + H2O(l). Use the following thermochemical equations to obtain ΔGr0 at 25 °C for the combustion of acetylene: C2H2(g) + 3H2(g) → 2CH4(g) ΔGr0 = −310.7 kJ/mol at 25 °C CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔGr0 = −817.97 kJ/mol at 25 °C H2(g) + 1/2O2(g) → H2O(l). ΔGr0 = −237.18 kJ/mol at 25 °C
Methane (CH4) burns in air to form carbon dioxide and water as shown below. CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) If a sample of methane occupies 426. mL at 2.31 atm, what volume (in mL) of oxygen gas at the same temperature and pressure is required to complete the reaction?
Natural gas burns in air to form carbon dioxide and water, releasing heat. CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔHorxn = -802.3 kJ You may want to reference (Page 269) Section 6.6 while completing this problem.What minimum mass of CH4 is required to heat 85.0 g of water by 23.0 ∘C? (Assume 100% heating efficiency.) (For water,Cs= 4.18 J/g∘C).
106. The combustion of liquid ethanol (C,H,OH) produces carbon dioxide and water. After 4.62 ml of ethanol density = 0.789 g/ml) is allowed to burn in the presence of 15.55 g of oxygen gas, 3.72 ml. or water (density = 1.00 g/mL) is collected. Determine the limiting reactant, theoretical vield of H.O. and percent yield for the reaction. Ilint: Write a balanced equation for the combustion of ethanol.)
