In a coffee press, you combine solid coffee grounds and hot water. After a long time, the ground coffee beans are still visible, and the water has turned into a rich dark brown (some of the coffee has dissolved into the liquid). You push the filter in the press down and pour out only the dark water into a cup. You then add milk and sugar to the cup. You also notice that the filter must have a hole in it because there are coffee grounds also in your cup. Calculate the degree of freedom in this system (your cup) at equilibrium. 1 2 3 4

The process of liquid water forming from water vapor is an: Endothermic process, because energy is released from the system due to breaking of interactions between water molecules. O Exothermic process, because energy is released from the system due to formation of interactions between water molecules. O Endothermic process, because energy is absorbed by the system due to breaking of interactions between water molecules. O Exothermic process, because energy is absorbed by the system due to formation of interactions between water molecules. MacBook Air DII DD O00 80 F8 F9 F7 F5 F6 F3 F4 & #3 3 4 6. 7 8

Consider an internal combustion engine like that used in automobiles. The most common fuel used here is gasoline which is a mixture of hydrocarbons, and an octane rating is given for standardization. Therefore, we will approximate gasoline as being composed of the hydrocarbon, octane, C8H18. Another fuel that is common in racing applications is nitromethane, CH3NO2, used in top fuel dragsters. Let’s consider the combustion of each fuel with oxygen in an internal combustion engine. Let the 8-cylinder engine displacement be 500 in3 total. GOAL: Determine and compare the maximum enthalpy of reaction, ∆Ho rxn, for the combustion of both octane and nitromethane in a single cylinder of the engine. This means determine the maximum amount of fuel that can burn in the cylinder filled with 1 atm of air and the amount of heat that reaction would generate. Here are some suggested steps to guide you along. You will have to look up some data in your book or on the internet. 1. Write a balanced…

A student dissolves 10.8 g of ammonium nitrate (NH4NO₂) in 250. g of water in a well-insulated open cup. He then observes the temperature of the water fall from 20.0 °C to 16.1 °C over the course of 8.4 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH4NO3(s) NH(aq) + NO3(aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 2 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case. Calculate the reaction enthalpy ΔΗ per mole of NH4NO3. rxn exothermic…
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.
