The density of ethanol is 0.79 g/ml. the density of acetic acid is 1.05 g/ml. assuming that each
substance was a pure substance, calculate the moles of each reactant used in part 2. determine the
limiting reactant, and calculate the theoretical yield of ethyl acetate. use the actual yield to determine
the percent yield of product.

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.

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.

All of the following are part of the biosphere except
