create a table that describes the three common states of matter in terms of their shape, volume, and compressibility.
1 answer:
Check attached for the table.
The explanation behind the table:
Solid – has definite shape and volume because if you hold any solid and put in anywhere it will not change.
Liquid – has definite volume and indefinite shape because the liquid take the shape of its container but with the same volume.
Gas – has indefinite shape and volume because the gas takes the shape and volume at its container.

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 = =
