Using the appropriate bond energies, calculate the heat of reaction AH for the following reaction: CI CI CI- C- CI + H- H CI-C - CI + H– CI CI H You can find a table of bond energies by using the Data button on the ALEKS toolbar. Round your answer to the nearest kJ/mol. Note: For clarity, all lone pairs have been omitted from the molecular structures. kJ ? mol

What is the enthalpy of combustion of ethane, C,H,, in kilojoules per mole of ethane? STRATEGY 1. Write the balanced chemical equation for the reaction. 2. Using the coefficients from the balanced equation, calculate AHn- 3. Scale the heat of reaction to be per mole of ethane. 4. Convert the heat released from kilojoules per mole to kilojoules per gram. Steps 1 and 2: The balanced chemical equation and AHn are given here. 2C,H,(g) + 70,(g) → 4 CO,(g) + 6 H,O(1) AHn = -3120.8 kJ Step 3: This amount of heat, 3120.8 kJ, is released per 2 mol of ethane according to the balanced chemical equation. How much heat is released when just one mole of ethane is burned? heat released: kJ -C,H, mol

Im doing a lab report.  were suppose to find the heat of reaction and the enthalpy of reaction. I dont understand which formulas to use. in the attachment please explain these two formulas, why are there two different ones for qrxn??? which one do I use? Can you help me calculate that and enthalpy of reaction with the following information. mass of contents of calorimeter=46.02 moles of magnesium used= .006m change in temperature = 14.1 C calorimeter constant= 5.39J/C Mg+2HCL=MgCl2+H2 This is the balanced equation right?

Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant- pressure calorimeters and constant-volume (or "bomb") calorimeters. Part A A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer; energy changes in a reaction are observed via a temperature change of the solution in the cup. Bomb calorimeters are used to measure combustion and A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 175 g of solution. The reaction caused the temperature of the solution to rise from 21.00 to 24.70 °C. What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water. Enter your answer in kilojoules per mole of compound to three significant figures. other gas-producing reactions, where the reaction…

What is the enthalpy of combustion of ethane, C, H,, in kilojoules per mole of ethane? STRATEGY: 1. Write the balanced chemical equation for the reaction. 2. Using the coefficients from the balanced equation, calculate AH. 3. Scale the heat of reaction to be per mole of ethane. 4. Convert the heat released from kJ/mol to kJ/g. Step 1: The balanced chemical equation for the reaction is 2C,H,(g) + 70,(g)4 CO,(g) + 6 H,O(1) Step 2: What is AH for the reaction as written? Heat of formation values can be found in the thermodynamic properties table. AHn = kJ/mol reaction
