El aire exhalado contiene 74,5g de N2, 15,7g de O2, 3,6g de CO2 y 6,2g de H2O. En un espacio de 2.1 L y 37°C a. Calcule la fracción molar de cada gas

b. Calcule la presión parcial de cada gas

c. Calcule la presión total del sistema.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
