The energy diagram shown represents the chemical reaction between solid ammonium chloride and solid barium hydroxide octahydrate:
2NH4 Cl(s) + Ba(OH)2 * 8H2 -----> 2NH3(aq) + BaCl(aq)
The for this reaction is 54.8 . How much energy would be absorbed if 25.1 of reacts?
For the cyclohexanes substituted in the positions indicated, identify the substituents as either axial or equatorial in chair conformers. For example, a 1,2-cis relationship means that one substituent must be axial and one equatorial.
