The additives complicate the math a bit, but the stoichiometric ratio is around 14 for many fuels. The equivalence ratio is just the actual air-to-fuel ratio divided by the theoretical.11. Look for carbons with four different groups attached to identify potential chiral centers. Draw your molecule with wedges and dashes and then draw a mirror image of the molecule. If the molecule in the mirror image is the same molecule, it is achiral. If they are different molecules, then it is chiral.

The vapour pressure of water at 80º C is 355 torr. A 100 ml vessel contained water saturated oxygen at 80º C, the total gas pressure being 760 torr. The contents of the vessel were pumped into a 50.0 ml, vessel at the same temperature. What were the partial pressures of oxygen and of water vapour, what was the total pressure in the final ...Whereas in the pyridinium ion - pyridine case. we can't draw good resonance structures that stabilize the positive charge in the pyridinium ion - this makes pyridinium ion more acidic. Both factors operate in the same direction and tend to make the pyridinium ion (pKa = 5.5 p K a = 5.5) more acidic than the iminium ion (pKa p K a ∼ ∼ 9). Share.The overlap is actually in making the boards and the electronics. What materials and what properties something has and why you would use it in a computer.
