Anna was asked to identify and explain if the equation CO2 (l) → CO2 (g) was an endothermic or exothermic reaction. However she got it wrong. What is her error and what should the answer have been?
Anna's statement: The equation is an exothermic reaction because the energy is released from liquid CO2 to the surroundings to become gaseous CO2 causing the molecules to slow down.
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.

The air filter which they had been using is fully saturated and no longer works. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You remember that the astronauts have a container of 14.5 kg of sodium hydroxide on the ship. As a chemical engineer, you know that sodium hydroxide can be used to remove carbon dioxide from the air by producing sodium carbonate and dihydrogen monoxide. How many liters of carbon dioxide are cleaned by the amount of sodium hydroxide given in the problem? The astronauts have 3 days left before they land on earth. You know that there are 4 astronauts, and each astronaut emits roughly 700 grams of carbon dioxide (CO2) each day. • How many liters of CO2 are produced by the astronauts? • Is there enough NaOH for the astronauts to survive the rest of their trip? If the astronaut survived the trip, how much NaOH was left over? If the astronaut…arrow_forward

- Coal-fired power plants emit CO2, which is one of the gases that is of concern with regard to global warming. A technique that power plants can adopt to keep most of the CO2 from entering the air is called CO2 capture and storage (CCS). If the incremental cost of the sequestration process is $0.019 per kilowatt-hour, what is the present worth of the extra cost over a 3-year period to a manufacturing plant that uses 100,000 kWh of power per month? The interest rate is 12% per year compounded quarterly.arrow_forwardgiven with the correct answer by my professor, but there was no explanation on how this correct or show the steps to getting the answer.

- The chart shows average CO2 emissions for fossil fuel vehicles (gasoline, diesel, and hybrid gas‑electric), as well as electric vehicles. The ordinate is mg CO2 per mile driven per pound mass of the vehicle (called curb weight). For electric vehicles, CO2 emission varies in U.S. states because of the mix of fuels used to generate electricity. If electricity came entirely from solar power, there would be little CO2 associated with its production. California has the lowest CO2 emission for producing electricity and Ohio has the highest because it depends heavily on coal‑fired power plants. The chart does not include CO2 emission from manufacturing vehicles. When normalized for distance driven by each kind of vehicle before it is scrapped, CO2 emission associated with manufacturing electric vehicles is estimated to be 25–75% greater than CO2 emission associated with manufacturing gasoline and diesel vehicles. If manufacturing were included, CO2 emission associated with electric vehicles…arrow_forward||| O CHEMICAL REACTIONS Balancing chemical equations with interfering coefficients Balance the chemical equation below using the smallest possible whole number stoichiometric coefficients.
