1. The Garden Center sells an item that it buys for $2.50 and sells for $5.75. The addition of $3.25 is an increase of 130% of the cost ($3.25 ÷ $2.50). The difference between the Garden Center's cost and the selling price ($3.25) is the gross margin. This is an example of __________________________.

The text provided contains several spelling, typographical, and grammatical errors. Additionally, there are formatting issues and mathematical errors related to the square root symbol. The correct version of the text is as follows: TNT - Products water vapor, nitrogen gas, and carbon dioxide. Balanced equation: C7H5N3O6(s) + 21/4 O2(g) → 7CO2(g) + 3/2 N2(g) + 5/2 H2O 1. Determine the theoretical reaction enthalpy (in kJ/mol) using bond enthalpies to calculate the enthalpy of the explosion reaction. (See example Using Bond Energies to Calculate Approximate Enthalpy Changes from your textbook). The bond enthalpy for the C=O bond in carbon dioxide is 799 kJ/mol. Also, there is not a value in the table in your book for a nitrogen-oxygen double bond (N=O). Use 600 kJ/mol for that calculation. You may use this template to organize your calculation. See this video for a walk-through on how bond enthalpies are used to determine heats of reaction. 2. Your textbook states, “A standard enthalpy of formation ΔHf is an enthalpy change for a reaction in which exactly 1 mole of a pure substance is formed from free elements in their most stable states under standard state conditions. These values are especially useful for computing or predicting enthalpy changes for chemical reactions that are impractical or dangerous to carry out, or for processes for which it is difficult to make measurements. I think that sounds like explosive reactions! a. Using the enthalpy of formations from appendix G of your text and the enthalpy of reaction determined in 2) above, calculate a theoretical enthalpy of formation for your explosive compound. Remember, ΔHrxn = ∑n × ΔHf0(products) - ∑n × ΔHf0(reactants) Explain all your work to help everyone (and yourself) understand your calculations. b. Comment on the sign and magnitude of the enthalpy of formation for your explosive. Is it large positive or large negative? What does the positive or negative mean anyway? • A type of work called expansion work (or pressure-volume work) occurs when a system that produces gases pushes back the surroundings against an outside pressure. Remember the volume of gas produced from the 1 gram of your explosive? Given the volume of gas produced, determine the work done (in kJ) upon the expansion of the gases from the explosion of 1 g of explosive. Assume the atmospheric pressure is 1 atmosphere. Remember, w = -PDV and the conversion factor for Joules and change in volume against a pressure is 1 L atm = 101.3 Joules. • Back to heat produced from an explosion! Determine the heat energy (kJ) produced from a 1 kg amount of your explosive by using the enthalpy of reaction you determined above in number 2. • Your explosive reaction from 2. above should have resulted in a negative enthalpy change, which is indicative of an exothermic reaction. Remembering the definition of “exothermic”, write a sentence or two on how this “exothermicity” may affect the value for the volume of gas you used to calculate expansion work in #4.

QUESTION 96 Rape myths do all of the following, except: Run counter to many of the basic facts about sexual violence (e.g., "mental illness often leads people to rape") "Actually" explain the root cause of rape (e.g., "it's connected to toxic masculinity") Deflect attention from the act of rape to the actions of the rape survivor (e.g., "she asked for it") Reflect and shape how societies think about sexual violence (e.g., "boys will be boys")

The BSD rev Utility: "[rev] copies the specified file(s) to the standard output, reversing the order of characters in every line." Write a C program to implement rev. Your program should take a single file as input and reverse each line to stdout. Your implementation may limit the maximum line size to 1024. Use of stdio.h functions is not allowed, only system calls. perror() is allowed. Use the built-in rev command to verify your program where the following 2 commands should produce the same result: $ rev testInput.txt $ ./MyRev testInput.txt

A continuous rectification column is to be designed to separate 6,500 kg/h of a mixture of 12.5% (w/w) methanol and water into an overhead product containing 90.3% (w/w) methanol using a reflux ratio 1.5 times the minimum value. A bottom product contains 1.0% (w/w) water. The feed is a saturated vapor. Methanol and water can be considered as ideal systems with a relative volatility of about 3.78. Calculate mol/h distillate, mol/h bottoms, and the number of theoretical trays needed using the McCabe-Thiele method.
