Question

How many grams of liquid methanol must be combusted to raise the temperature of $454 \mathrm{g}$ of water from $20.0^{\circ} \mathrm{C}$ to $50.0^{\circ} \mathrm{C} ?$ Assume that the transfer of heat to the water is $100 \%$ efficient. How many grams of carbon dioxide are produced in this combustion reaction?

Answers

Find H for the combustion of ethanol (C2H6O) to carbon dioxide and liquid water from the following data. The heat capacity of the bomb calorimeter is 34.65 kJ/K, and the combustion of 1.765 g of ethanol raises the temperature of the calorimeter from 294.33 K to 295.84 K.
