Allisa [31]

Answer:

Particles in a liquid move randomly and can slide past each other but they don't move far away from each other. Particles in liquids are close together, rolling over each other and arranged randomly. Particles in a solid vibrate in all directions but cannot move out of their fixed positions.

What is the % yield of the reaction making 1.6 g of acetyl salicylic acid from 5.7 g of salicylic acid, 9.9 mL of acetic anhydri

artcher [175]

Answer:

Yield of reaction is 76.7%

Explanation:

The reaction of salicylic acid with acetic anhydride to produce acetyl salicylic acid is 1:1. That means 1 mole of salicylic acid reacts with 1 mole of acetic anhydride (Acid is catalyst of reaction).

Moles of salicylic acid are:

$5.7g\frac{1mol}{138.121g} = 0.04127 moles$

And moles of acetic anhydride are:

$9.9mL\frac{1.082g}{mL} \frac{1mol}{102.09g} = 0.105 moles$

As salicylic acid is limiting reactant, theoretical moles of acetyl salicylic acid are 0.04127mol. That means theoretical mass of acetyl salicylic acid is:

$0.04127moles\frac{180.158g}{1mol} = 7.435g$
