Concept introduction: Thermodynamics is a study of energy transfers that can be done by either heat or work. The energy transferred through work involves force. When work is positive then the system gains energy while when work is negative then the system loses energy. Heat is not a state function and therefore change in enthalpy of reaction

Organic Chemistry: Structure and Function
- Draw the structures of the starting materials or major products for each of the following reactions (if no reaction is expected to occur, write NO REACTION); H,SO, A + heat он H2/Pd H,SO4 > B heat KMNO4 D HO.arrow_forwardOH H₂SO4 cat. SN2 conditionsarrow_forwardTwo useful organic compounds that contain Cl atoms are vinyl chloride (CH2 = CHCI) and chloroethane (CH;CH;CI). Vinyl chloride is the starting material used to prepare poly (vinyl chloride), a plastic used in insulation, pipes, and bottles. Chloroethane (ethyl chloride) is a local anesthetic. Why is the C – Cl bond of | vinyl chloride stronger than the C – Cl bond in chloroethane.arrow_forward

Less energy can be obtained when oxidizing the -(HCOH)-group than the -(CH₂)- group O b. The more reduced a C atom, the more energy can release when oxidized Oc. In carbon dioxide (CO₂), C is the most oxidized form Od.

(a) Write a balanced equation for the complete combustion of propane gas. (b) Calculate the volume of air at 25 °C and 1.00 atmosphere that is needed to completely combust 25.0 grams of propane. Assume that air is 21.0 percent O2 by volume. (Hint: We will see how to do this calculation in a later chapter on gases—for now use the information that 1.00 L of air at 25 °C and 1.00 atm contains 0.275 g of O2 per liter.) (c) The heat of combustion of propane is −2,219.2 kJ/mol. Calculate the heat of formation, ΔH∘fΔHf° of propane given that ΔH∘fΔHf° of H2O(l) = −285.8 kJ/mol and ΔH∘fΔHf° of CO2(g) = −393.5 kJ/mol. (d) Assuming that all of the heat released in burning 25.0 grams of propane is transferred to 4.00 kilograms of water, calculate the increase in temperature of the water.arrow_forwardFormation of ammonia from nitrogen and hydrogen is an exothermic process. Which of the following statements is true about the bonds that are broken and formed during this reaction?
