1. As we know a;; homes used hot water tank and every hot water tank is an anode(called a dip tube) with the time this erode away in to the H2O now explain what health risks may arise people use this hot water in the preparation and cooking ?
2. What is the equilibrium constant for this reaction (1/2) N2(g) + (1/2) O2(g) <===> NO(g) at 1000 K if free energy of formation of NO = 78 kJ mol¯1 at the temperature of an automobile engine (1000 K). ?
