Classify the following processes as exothermic or endothermic: (a) Freezing of water ____ (b) Evaporation of alcohol ____ (c) Fire logs burning ____ (d) A baby growing ____ The specific heat of gold is 0.128 J/g. degree C. A gold-colored solid weighing 4.70 g absorbs 57.2Jof heat. Its temperature rises from 25.0 degree C to 57.0 degree C. Calculate the specific heat of the gold-colored solid. Is the gold-colored solid pure gold based on the specific heat values? A liquid propane tank contains 13.2 kg of propane, C_3H_8 Using the thermochemical equation for the combustion of propane given below, calculate the heat released when all the propane in the tank is burned. C_3H_8(g) + 5 O_2(g) rightarrow 3 CO_2 (g) + 4 H_2O (g) delta H_r times n = -2044 kJ The thermochemical equation for the combustion of one mole of carbon monoxide is as follows: CO_2(g) + 1/2 O_2 rightarrow CO_2(g) Delta H = -283 kJ Calculate the heat change for the decomposition of 2.00 lb carbon dioxide gas into CO and oxygen.
