Use average bond enthalpies (linked above) to calculate the enthalpy change for the following gas-phase reaction. C2H4(g) + Br2(g) CH,BRCH,Br(g) To analyze the reaction, first draw Lewis structures for all reactant and product molecules. • Include all valence lone pairs in your answer. • Draw the reaction using separate sketchers for each species. One molecule per sketcher, please. Separate multiple reactants and/or products using the + sign from the drop-down arrow. Separate reactants from products using the If you have to draw H,, draw H-H. • Be sure that your structural equation is balanced. symbol from the drop-down menu.

Try Again Row 3: Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. A student runs two experiments with a constant-volume "bomb" calorimeter containing 1100. g of water (see sketch at right). First, a 7.000 g tablet of benzoic acid (CH₂CO₂H) 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 15.00 °C to 53.26 °C over a time of 12.3 minutes. Next, 5.420 g of acetylene (C₂H₂) are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from 15.00 °C to 74.42 °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…

Could someone please help! No plagiarism Please! 3. Draw an or find an image of an endothermic reaction or an exothermic reaction. Explain what makes it the type of reaction you chose to illustrate. Include arrows to show what direction the overall enthalpy of reaction (energy of reaction) flows.    4.  Ammonium nitrate dissolves in water via the following reaction: NH4NO3(s) → NH4+(aq) + NO3-(aq) The bond energies of the compounds in the reaction are as follows: NH4NO3 =   3040 kJ/mol NH4+ = 1564 kJ/mol NO3- = 1009 kJ/mol How much total energy does the reaction have, and how will the environment change when the reaction occurs? Please show all of your work

Question 11 X Incorrect. Isooctane, C3H18, is the basis of the octane rating system for gasoline because it burns smoothly, with minimal engine knocking. Pure isooctane is assigned a value of 100. Octane ratings are assigned to gasoline mixtures based on their ability to prevent knocking relative to isooctane. Estimate the energy released during the combustion of 1.00 mol of pure isooctane. Please note the combustion is exothermic process and the released energy is positive for the surroundings. -285.8 kJ

A 3.59°C increase in temperature occurs when a 0.232 g sample of benzoic acid (C7H6O2) is combusted in a bomb calorimeter. A 1.81 °C increase in temperature occurs when a 0.303 g sample of citric acid (C6H8O7) is combusted in the same bomb calorimeter. The heat of combustion of benzoic acid is -26.37 kJ/g. What is the molar heat of combustion of citric acid? Reminder: Any heats of combustion will be negative since these are exothermic reactions.

CSCI has a lattice energy of -657 kJ/mol. Consider a generic salt, AB, where A²+ has the same radius as Cs*, and B has the same radius as Cl. Estimate the lattice energy of the salt AB. lattice energy of AB: kJ/mol
