Guanidine is a stronger base than the typical amine. The increased basicity can be explained by drawing the resonance structures of the protonated guanidine. The protonated guanidine (A) has been drawn for you. Draw major resonance structures, B and C, and one minor resonance structure, D. Be sure to include the formal charge, lone pairs, and hydrogens on nitrogen for structures B, C, and D.

The twister and runaway train are two coasters at the same amusement park. both coasters start at the same height. the coaster for the twister is twice the mass of the coaster for the runaway train. which roller coaster has greater gravitational potential energy at the start of the ride?

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?

Using this reversible reaction, answer the questions below: n2o4 2no2 (colorless) (reddish-brown) -as the temperature increased, what happened to the n2o4 concentration? -was the formation of reactants or products favored by the addition of heat? -which reaction is exothermic? right to left or left to right? -if the change of enthalpy of this reaction when proceeding left to right is 14 kcal, which chemical equation is correct? n2o4 2no2 + 14 kcal n2o4 2no2, hr = +14 kcal n2o4 + 14 kcal 2no2 n2o4 2no2, hr = -14 kcal
