Percentage recovery gives us an idea of the amount of pure substance recovered after the chemical reaction. Percentage recovery can be more than 100 % or less than 100 %. Usually, in any experiment performed the weight percentage recovery will be less than 100. Percent recovery values greater than 100 show that the recovered compound is contaminated.
Amount of acetaminophen initially taken = 350 mg
Amount of acetaminophen obtained after recovery =185 mg
![Weight percentage recovery =\frac{mass recovered}{mass originally taken}*100](https://tex.z-dn.net/?f=Weight%20percentage%20recovery%20%3D%5Cfrac%7Bmass%20recovered%7D%7Bmass%20originally%20taken%7D%2A100)
= ![\frac{185 mg}{350 mg}*100](https://tex.z-dn.net/?f=%5Cfrac%7B185%20mg%7D%7B350%20mg%7D%2A100)
= 52.9%
In acidic solutions you have H+ but in basic solutions you have OH-.
You need know that for to balance the reaction.
Answer:
Atoms are indivisible
I had a hard time finding this out.
Explanation: Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.
