Remember the cumulative frequency HW? We need to find the mode, median and mean of the data set too.

The questions.
2) Differentiate CNS (central nervous system) from PNS (peripheral nervous system)3) Define Autonomic Nervous System
4) Differentiate parasympathetic and sympathetic
5) Give different neurotransmitters and functions

19.44Use data in Appendix C to calculate for ΔHº, ΔSº, and ΔGº at 25ºC for each of the ff reactions. In each case show that ΔGº = ΔHº - TΔSº.
(a) Ni(s) + Cl2(g) → NiCl2(s)
(b) CaCO3(s, calcite) → CaO(s) + CO2(g)
( c) P4O10(s) + 6H2O(l) → 4H3PO4(aq)
(d) 2CH3OH(l) + 3O2(g) → 2CO2(g) + 4H2O(l)

Using data in Appendix C, calculate ΔG for each of the ff reactions. In each case indicate whether the reaction is spontaneous under standard conditions (25ºC, 1 atm).
(a) H2(g) + Cl2(g) → 2HCl(g)(b) MgCl2(s) + H2O(l) → MgO(s) + 2HCl(g)
( c) 2NH3(g) → N2H4(g) + H2(g)
(d) 2NOCl(g) → 2NO(g) + Cl2(g)
