What is [H+] given that the measured cell potential is -0.464 V and the anode reduction ... What half-reaction occurs at the cathode during the electrolysis of molten ... PbO2(s) + 4H+(aq) + SO42-(aq) + 2e- → PbSO4(s) + 2H2O(l); E° = 1.69 V .... For the cell Cu(s)|Cu2+||Ag+|Ag(s), the standard cell potential is 0.46 V. A cell ... hopw this helps
Answer:
Possibly 18.0
Explanation:
2.016 H (2*1.008) + 15.999 O (1*15.999)
When the temperature is cold, barely any of the liquid rises, so most of it is at the bottom.
When the temperature is hot, the liquid rises up, so the liquid is distributed about evenly across the thermometer's tube.
Air is a mixture of gasses, including nitrogen, oxygen, carbon dioxide and water vapour, as such it is always chemically impure.
