Answer: Signal at 3230-3350 shows an O-H (alcohol) (1) and C=O at 1680-1750 (1) There are separate -OH and C=O bonds in the molecule, so it is not a carboxylic acid. how big are parking spotsWebSince the Ag + / Ag half-cell has a more positive Eꝋ value, this is the positive pole and the H + /H 2 half-cell is the negative pole. The standard cell potential (Ecellꝋ) is Ecellꝋ = (+ 0.80) - (0.00) = + 0.80 V. The Ag + ions are more likely to get reduced than the H + ions as it has a greater Eꝋ value. how big are peacock eggsWebOcr chemistry a data sheet.
