Chlorine has 17 total electrons with electron configuration 1s^2 2s^2 2p^6 3s^2 3p^5. What are the first three quantum numbers for the sic electrons in the 2p subshell?

State the formula for density in words and mathematical symbols

Based on the equation and the information in the table, what is the enthalpy of the reaction?

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
