How does this error affect the final temperature measured in the experiment (compared to the value that would be obtained without the error)? While using a coffee cup calorimeter in this experiment, some heat was lost to the environment.
Describe your reasoning for the key steps which allow you to employ a ray diagram to find out the refractive index of the material from which the sphere is formed.
At what temperature will 15 percent of the molecule be in the upper state? A certain molecule has a doubly degenerated excited state lying at360 cm-1 above the non-degenerated ground state.
Determine the temperature of a two-level system of energy separation equivalent to 300 cm-1 when the population of the upper state is one-half that of the lower state.
4-Carbon disulfide is a colorless liquid. When pure, it is nearly odorless, but the commercial product smells vile. Determine the standard enthalpy change for this reaction using standard enthalpies of formation.
Determine the resulting total pressure in the third vessel. Suppose the temperature remains constant and the gasses behave ideally. A 10.0 L vessel contains gas X at a pressure of 300 torr.
The heat released by this reaction is sufficient to ignite paper. Explain how much heat is released when the 21.5 g of calcium oxide reacts? Calcium oxide reacts with the water to form the calcium hydroxide (slaked lime).
Determine the maximum temperature of the solution after mixing? Suppose you mix 21.1 g of water at 66.2°C with the 45.2 g of water at35.7°C in an insulated cup.
