A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.6158 g sample of benzoic acid (C7H6O2) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.148x10³ g of water. During the combustion the temperature increases from 27.72 to 30.66 °C. The heat capacity of water is 4.184 J g-¹°C-¹. The heat capacity of the calorimeter was determined in a previous experiment to be 902.7 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of benzoic acid based on these data. C₂H6O₂ (s) + (15/2) O₂(g) →→3 H₂O(1) + 7 CO₂(g) + Energy Molar Heat of Combustion = kJ/mol Submit Answer Calorimeter Calculations: This is group attempt 1 of 10 MacBook Air Autosaved at 9:03 PM Ignition wires heat sample Insulated outside chamber Water Stirrer…

The heat of reaction for the combustion of cyclobutane, C,Hg, is 650.3 kcal/mol. What is the heat of combustion for cyclobutane in kcal/gram? kcal/gram How much heat will be given off if molar quantities of cyclobutane react according to the following equation?

The heat of neutralization, Hneut, can be defined as the amount of heat released (or absorbed), q, per mole of acid (or base) neutralized. Hneut for nitric acid is -52 kJ/mol HNO3. At 27.3C, 50.00 mL of 0.743M HNO3 is neutralized by 1.00 M Sr(OH)2 in a coffee-cup calorimeter. (a) How many mL of Sr(OH)2 were used in the neutralization? (b) What is the final temperature of the resulting solution? (Use the assumptions in Question 11.)
Although the gas used in an oxyacetylene torch (Figure 5.7) is essentially pure acetylene, the heat produced by combustion of one mole of acetylene in such a torch is likely not equal to the enthalpy of combustion of acetylene listed in Table 5.2. Considering the conditions for which the tabulated data are reported, suggest an explanation.
During the combustion of 5.00 gg of octane, C8H18C8H18, 239.5 kcalkcal (1002 kJkJ) is released. what is the balanced equation for the combustion reaction? How much energy (in kJkJ) is released by the combustion of 1.21 molmol of C8H18C8H18 ? How many moles of octane must be burned to release 442.4 kcalkcal ? How many kilocalories are released by the combustion of 18.3 gg of C8H18C8H18 ?
Carbohydrate Requirements (sugars and starch in rice, potato, pasta, bread, sugar, fruits, ete.) : The Institute of Medicine recommends adults consume on average 50 percent of their daily calories from carbohydrates. Since carbohydrates contain about 3.94 calories in each gram and recommended daily calories intake for an average person is 2,100 cal, calculate how many grams of carbohydrate average person need to eat per day? (Hint: first find how many calories should be coming from the carbs, then convert them to grams). Use two sig figs for this answer and the other two below, and enter number only, no units. Protein Requirements (high-protein foods include lean meats, poultry, seafood, soyysroducts, eggs, dairy foods, nuts and seeds): Adults should consume about 20 percent of their energy intake from protein. Since protein provides 5.65 calories per gram, if a person eats a 2,100-calorie diet, how many grams of protein does he/she need to consume daily? Fat Requirements (eat healthy…
