An electrochemical cell was constructed from snsn2 and
An electrochemical cell was constructed from Sn/Sn2+ and Pb/Pb2+ with KNO3 as the salt bridge. The concentrations were Sn2+ =1.0M and Pb2+ = 0.1M.
Sn2+ + Pb --> Sn + Pb2+
Is the above reaction spontaneous under the conditions given? Explain.

KHP is an acid that is monoprotic and hardly hygroscopic. When carbon dioxide reacts with NaOH it produces sodium carbonate. I kind of understand how to do part b but i really don't understand how to do part a.
A 3-phase 230 V, 9 kVA, 0.9 PF (lagging) load is supplied by 10 kVA, 1330/230 V, 60 Hz three-phase transformer connected in Y-?. The equivalent impedance of transformer referred to the low-voltage side is 0.12 + j0.25.
One bit of evidence that the present theory of atomic structure is "correct" lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit paramagnetism.
