For the reaction below, the molecular weight of A is 100 g/mol, the molecular weight of B is 75 g/mol, and the molecular weight of C is 80 g/mol. A + B → C + other unimportant products Suppose you have 250mg of A and 250mg of B. What is the limiting reagent here?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

How many absorptions would you expect to observe in the 13c nmr spectra of the following molecules? a) 3-chloropentane b) cis-4-methyl-2-pentene

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
