How many grams of .49% wt% aqueous HF are required to provide a 25% excess to react with 25 mL of .023 M Th^4+ by the reaction Th^4+ + 4F^- --> ThF4?
To better understand why, scientists synthesized artificial protein mimics that were linked by ester bonds instead of the amide functionality ( the R-group side chains all remained the same). They found that these mimics did not form highly organi..
