A researcher studying the nutritional value of a new candy places a 3.30 g sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.02 °C. If the heat capacity of the calorimeter is 40.50 kJ-K-¹, how many nutritional Calories are there per gram of the candy? Calories per gram of candy: x10 TOOLS 000 Cal/g

When 9.1 g of a  hydrocarbon is combusted in a bomb calorimeter the temperature of the calorimeter increases from 23.8 C to 53.5 C. The calorimeter contains 731 g of water and the heat capacity of the bomb is 872 J/ C​. Please calculate q rxn​, in kJ, for the combustion of the hydrocarbon.

A particular container holds 3.77 mol of neon gas. The volume of this container can be altered by sliding a piston in or out. The volume is changed from 8.60 L to 12.20 L while at the same time the temperature is changed from 303 K to 345 K. The molar heat capacity, Cym, for neon is 12.47 J/(mol · K). Assume that this value will not change over the given temperature range. What is the change in entropy for the gas? AS = J/K TOOLS x10 MacBook Pro

a chemist wastes a delicious brownie by burning it in a bomb calorimeter. before burning, the brownie weighed 16.13 grams. During the combustion process in the bomb calorimeter, the heat of the calorimeter increased by 7.40 degrees celsius. The known heat capacity of the calorimeter that was used was 26.53 kJ/Celsius. What is the energy content, in kJ/g, of this brownie?

A 56.1 g sample of polystyrene, which has a specific heat capacity of 1.880 J-g °C-1 is put into a calorimeter (see sketch at right) that contains 250.0 g of water. The temperature of the water starts off at 24.0 °C. When the temperature of the water stops changing it's 29.8 °C. The pressure remains constant at 1 atm. Calculate the initial temperature of the polystyrene sample. Be sure your answer is rounded to the correct number of significant digits. °C thermometer. insulated container water sample. a calorimeter 區 OU Ar

A bomb calorimeter has a heat capacity of 6.067 kJ/°C. A sample of vitamin (C31H4602) has an internal energy (DE) = -2.278 X 104 kJ/mol. When 1.434 g of the vitamin sample are burned in oxygen in the calorimeter, determine the final temperature in °C if the initial temperature is 14.51 °C.
