A gas containing only N2 and CH4 is burned with the air yielding a flue gas that has an or sat analysis ofCO2: 8.7%, CO: 1.0%, O2: 3.8%, andN2: 86.5%.
Explain how you could calculate the specific heat of a metal by using the techniques and apparatus in this experiment.
Discuss the specific heat of the metal when a piece of metal weighing 5.10 g at a temperature of 48.6 C was placed in a calorimeter into the 20.00 ml of water at the 22.1 C, and the final equilibri
The maximum potential energy that an atom can have is 0J, at which point the electron has essentially been removed from the nucleus; thus the atom is ionized.
