When a 50. mL sample of C₂H5OH is mixed with a 50. mL sample of H₂O, the resulting mixture has a volume of 95 mL, and the container is warm to the touch. Which of the following best describes these observations? A C D A chemical reaction occurs, as evidenced by the volume of the resultant mixture being less than the total volume of the initial components. A chemical change occurs, as evidenced by the formation of new covalent bonds releasing more energy than is absorbed by the breaking of the existing covalent bonds. A physical change occurs, and the solvation process is exothermic. A physical change occurs, and the solvation process is endothermic.

Chemical energy is released or absorbed from reactions in various forms. The most easily measurable form of energy comes in the form of heat, or enthalpy. The enthalpy of a reaction can be calculated from the heats of formation of the substances involved in the reaction: ΔΗn = ΣηΔΗ; (products) – Σπ.ΔΗ (reactants) where n represents the stoichiometric coefficients. Part A Calculate the standard enthalpy change for the reaction Use the following data: ΔΗ; Substance (kJ/mol) A B C D ΔΗ; = -237 -385 205 -515 Submit Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) μА Value Previous Answers 2A + B2C + 2D Review | Constants I Periodic Table Units ?

Suppose a boil water notice is sent out advising all residents in the area to boil their water before drinking it or using it for cooking. You need to boil 18.0 L of water using your natural gas (primarily methane) stove. What volume of natural gas is needed to boil the water if only 10.1% of the heat generated goes towards heating the water. Assume the density of methane is 0.668 g/L, the density of water is 1.00 g/mL, and that the water has an initial temperature of 21.4 °C. Enthalpy of formation values can be found in this table. Assume that gaseous water is formed in the combustion of methane.
