Question

1. A researcher studying the nutritional value of a new candy places a 5.90-gram sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.97 °C. If the heat capacity of the calorimeter is 29.00 kJ·K–1, how many nutritional Calories are there per gram of the candy?

2.An experimental spacecraft consumes a special fuel at a rate of 314 L/min. The density of the fuel is 0.830 g/mL and the standard enthalpy of combustion of the fuel is –47.3 kJ/g. Calculate the maximum power (in units of kilowatts) that can be produced by this spacecraft. 1 kW = 1 kJ/s
