A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter with a heat capacity of 14.25 kJ/°C. If the initial temperature was 32.9°C, use the information below to determine the value of the final temperature of the calorimeter. 4 C6H5NH2(l) + 35 O2(g) → 24 CO2(g) + 14 H2O(g) + 4 NO2(g) ΔH°rxn = -1.28 x 104 kJ

A 3.971 g sample of a new organic material is combusted in a bomb calorimeter. The temperature of the calorimeter and its contents increase from 24.87 ∘C to 28.06 ∘C. The heat capacity (calorimeter constant) of the calorimeter is 36.35 kJ/ ∘C, what is the heat of combustion per gram of the material?

Gram for gram, fats in food have much more chemical energy than sugar.  One component of fat is stearic acid, C18H36O2.  When a sample of 1.02 g of stearicd acid was burned completely in a bomb calorimeter, the temperature of the calorimeter rose by 4.26 oC.  The heat capacity of the calorimeter was 9.43 kJ/oC.  Calculate the molar heat of combustion of stearic acid in kilojoules per mole.  answer: (-11189 kJ/mol)

5) The combustion of sucrose (C12H22O11, molar mass = 342.3 g/mol) has a AErxn of -1.40 x 104 kJ/mol. When 1.25 grams of sucrose undergoes combustion in a bomb calorimeter, the temperature rises from 22.2 °C to 34.3 °C. What is the heat capacity of the bomb calorimeter? 0 5.39 kJ/C 05.90 ki 04.23 KJPC 04.90 ki/C

A researcher studying the nutritional value of a new candy places a 5.60 g5.60 g sample of the candy inside a bomb calorimeter and combusts it in excess oxygen.

A student runs two experiments with a constant-volume "bomb" calorimeter containing 1400. g of water (see sketch at right). First, a 5.000 g tablet of benzoic acid (CH-CO₂H) is put into the "bomb" and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is observed to rise from 21.00 °C to 42.00 °C over a time of 8.5 minutes. Next, 5.190 g of ethylene (C₂H4) are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from 21.00 °C to 63.35 °C. Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction: Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in the second experiment. exothermic C₂H₂(g) + 30₂(g) → 2CO₂(g) + 2H₂O(g) Be…

Consider a neutralization reaction in which NaOH(aq) is mixed with H2SO4(aq) in a coffee-cup calorimeter. If 165.0  g of liquid in the coffee-cup calorimeter rises 6.50 °C, how much heat is released by the neutralization reaction?
