Answer:
of acetic anhydride is needed
Explanation:
According to balanced equation, 1 mol of salicylic acid completely reacts with 1 mol of acetic anhydride
Number of moles = (mass)/(molar mass)
Molar mass of acetic anhydride = 102.09 g/mol
Molar mass of salicylic acid = 138.121 g/mol
So, 
of salicylic acid = 
of salicylic acid
Hence, of salicylic acid reacts completely with of acetic anhydride.
So, mass of acetic anhydride needed = 
=
2.55 moles H20 will be produced
Hydrogen Bond is the bond based on intermolecular forces between H and F O and N
<h2>Answer:</h2>
<u>In dry climates, rates of evaporation exceed precipitation</u>
<h2>Explanation:</h2>
Evaporation is an important process in the global water cycle. Sunrays hits the surface of water or land and causes water to change state from a liquid to a gas. This is what we call evaporation. When evaporation occurs, at the same time precipitation occurs in the atmosphere which is the water falling from the clouds as rain, freezing rain, sleet, snow, or hail. As the rate of evaporation increases, the rate of precipitations increases too because both are connected to each other.
