Extracted text: 5. A sample of a solid organic is completely combusted in a calorimeter. The heat generated by combustion is transferred to the water, causing the temperature of the water to increase. Based the date in the table below, which of the following is the best estimate of the heat of combustion, AH.combs of the organic solid? (The specific heat of water is 4.2 J/g°C) Mass of Mass of AT water Solid Water 1.0 g 2000.0 g + 2.1°C (A) +18 kJ/mol (B) +8.4 kJ/mol (C) -8.4 kJ/mol (D) -18 kJ/mol 6. Below is the heating curve for methane, CH. How much energy is required to melt 64 grams of methane at 90 K?
