Synthetic Natural Gas (SNG) has a molar composition of 96.59% CH4, 1.9% CO2, 1.29% H2, and 0.22% CO. One mole of SNG (GCV = 858.14 KJ/mol) was burned in a furnace to produce a burner gas at 250 degree C composed of 0.85 mol CO2, 0.12 mol CO, 0.08 mol O2, 1.5 mol N2 and 0.56 mol H2O. Calculate for thea. %CV loss due to sensible heatb. %CV loss due to unburnt COc. %CV loss due uncondensed waterd. Thermal efficiency of the combustion Use perry for Cp

A sample of the sugar D-ribose (C5H10O5) of mass 0.727 g was placed in a constant volume calorimeter and then ignited in the presence of excess oxygen. The temperature rose by 0.910 K. In a separate experiment in the same calorimeter, the combustion of 0.825 g of benzoic acid, for which the internal energy of combustion is -3251 kJ mol-1, gave a temperature rise of 1.940 K. Calculate the internal energy of combustion of D-ribose and its enthalpy of formation. Combustion Reaction: 5 C (s) + 5 H2 (g) + 2/5 O2 (g) → C3H19O5 (s) 5 С (5) + 5 02 (g) > 5 СO2 (g) 5 H2 (g) + 2/5 O2 (g) → 5 H2O (1) 5 СО2 (g) + 5 Н.O (1) — СsHi0Os (s) + 5 0г (g) AH°F298 = (5) (-39.351 x 107) AH°F298 = (5) (-28.584 x 107) AH°F F298 =

A stream flowing at a rate of 30kgmol/h containing 30% (mole) N₂ and 70% (mole) H₂. This is to be heated from 300 K to 470 K. Calculate the amount of heat transferred using the C data given below. CP N₂ = 29.57 - 5.43 × 10-³T + 13.17 x 10-672, kJ/kgmol -K CHH₂ = 28.65 +1.02 x 10-³T-0.15 x 10-672, kJ/kgmol - K

You have a calorimeter with 100 g of water at 22.6ᵒC and a 50.0 g piece of copper that you have heated to 98.7ᵒC. You place the copper in the water and wait for the temperature of the water to stop rising. What will be the highest temperature of the water? (Specific heats: water = 4.184 J/gᵒC, copper = 0.385 J/gᵒC )
