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:
And moles of acetic anhydride are:
As salicylic acid is limiting reactant, theoretical moles of acetyl salicylic acid are 0.04127mol. That means theoretical mass of acetyl salicylic acid is:
Thus, yield of reaction is:
<em>76.7%</em>

Answer:
which of these sentences contains a correctly formed possessive form of the name andres
Answer:
Following are the <span>conjugate acid-base pairs;
1) NH</span>₃ , NH₄⁺
2) CH₃CO₂⁻ , CH₃COOH
Explanation:
According to Brønsted–Lowry acid–base theory an acid is any specie which can donate H⁺. When an acid donates proton it is converted into conjugate base.
Example:
CH₃COOH + BASE → CH₃COO⁻ + Base-H
In above reaction Acetic Acid (CH₃COOH) is acid, and after loosing proton it is converted into conjugate base i.e. Acetate (CH₃COO⁻).
And according to Brønsted–Lowry acid–base theory base is any specie which can accept H⁺. When base accepts proton it is converted into conjugate acid.
Example:
NH₃ + A-H → NH₄⁺ + A⁻
In above reaction Ammonia (NH₃) is a base, and after accepting proton it is converted into conjugate acid i.e. Ammonium (NH₄⁺)
