2. A) The heat (Enthalpy) released by the combustion of glucose is the same whether it is consumed in a fire such as the burning wood or in metabolism in an animal's body. (A) How much heat is released when 100.0 grams of glucose are combusted according to the balanced thermochemical equation shown below? (B)Is this reaction endothermic or exothermic? C6H12O6(s) + 602(g) → 6CO2(g) + 6H2O(1) + 2803kJ
1) CH4(g)+2O2(g)→CO2(g)+2H2O(l)ΔHrxno=−889.1kJmol–1 ΔHfoH2O(l)=–285.8kJmol–1ΔHfoCO2(g)=–393.3kJmol–1 What is the standard heat of formation, ΔHfo, of methane, CH4(g), as calculated from the data above? 2) How much heat, in kilojoules, must be added to a 75.0–g iron block with a specific heat of 0.449 J/g°C to increase its temperature from 25 °C to its melting temperature of 1535 °C? 3) Calculate ΔH298o for the process Sb(s)+52Cl2(g)→SbCl5(g) from the following information: Sb(s)+32Cl2(g)→SbCl3(g)ΔH298o=−314kJ 4) The oxidation of the sugar glucose, C6H12O6, is described by the following...
