Predict the reaction at both the anode and cathode for the electrolysis of molten NaF(in molten NaF,only the ions are present,ie no water is present).
If 6.0 moles of ethene and 6.0 moles of hydrogen are introduced into a 2.0 L sealed vessel and allowed to equilibrate at 200ºC, what is the equilibrium concentration of the ethene
Draw all stereoisomers of 3-heptene. Position the groups attached to the double bond (120° bond angles) to indicate the stereochemistry.
The I2 that did not react with ascorbic acid is then determined in a thiosulfate reaction. If 40.0mL of 0.4445M I2 was added to a sample containing vitamin C, the unused I2 required 19.05mL of 0.142M S2O32- to react. How many moles of vitamin C we..
