Answer #1

16. Aus - Sublimation of carbon dioxide at -78°C is CO2 (s) ² CO2(g) ... Altsub= 25.2 kJ/ omol. We have change in entropy is17. Ams - The half cell reactions Ag+ (aq) + é Aq (s) Mgat lag + 2ē → Mg(s) are E = +0.800 = -2.37 v Since the electrode poteMg(s) + 2Apt (ag) Mght (aq) + 2A9 (s). Nernst equation, we have from Eell - Eid to a large com a to [ 0.100] = 3.17 : m=2=no.
