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.

Signal generator‘s internal impedance is purely resistive and has an open-circuit voltage of 3.5 V. When the generator is loaded with 22 ohms of resistance, its terminal voltage drops to 2.8 V. What is the generator's output impedance (pure
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.
