Acting as a reference point for detecting motion
Answer:
no
Explanation:
it is not endothermic reaction
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 =
=
