Draw the major and minor resonance structure for the carbonate ion (CO3^-2). Include any formal charges, Indicate which are the major resonance structures and why.
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why?
A voltaic cell is based on the reaction Sn(s)+ I2 (s) --> Sn^2+ (aq)+ 2I^- (aq). Under standard conditions, what is the maximum electrical work, in joules, that the cell can accomplish if 70.0 g of Sn is consumed?
