Like the cyanate ion (NCO-), the fulminate ion (CNO-) has three resonance structures. Which is the most important contributor to the resonance hybrid? Suggest a reason fro the instability of fulminate.
Homework Statement
Given solubility of Ba(NO3)2 is
34g/100 H20 at 100oC
5g/100g of H20 AT 0oC
if one starts with 100g of (BaNO3)2 and make a saturated solution in water at 100oC, and then cooled to 0oC, how much Ba(NO3)2 is crystallised out of solution?
The resultant crystals carry along...
The gas phase decomposition of ethylamine produces ethane and ammonia according to the following equation:-
C2H5NH2 (g) → C2H4 (g) + NH3 (g)
The following total pressures were found for this reaction at 500°C with an initial pressure of pure ethylamine equal to 55 mm Hg...
