An electrochemical cell is based on these two half-reactions: Ox: Sn(s)→Sn2+(aq,1.55molL−1)+2e− E∘anode=−0.14(V)
Red: ClO2(g,0.150bar)+e−→ClO−2(aq,1.55mo lL−1) E∘cathode=0.95(V)

Compute the cell potential at 25 ∘C.

Aconcentrated solution of ammonia is 14.8m and has a density of 0.899g/l. what is the concentration of ammonia in this solution in weight percent (%w/w)?

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol
