The two
Esters along with starting materials are shown below. The missing reagents ate shown in Blue encircled in red box. First reaction is carried out in acid which increases the reactivity of carboxylic acid (
electrophilicity odf carbonyl carbon). And second reaction is carried out in the presence of Base, which increases the
Nucleophilicity of nucleophile i.e. Alcohols.
Each isotope has a unique rate of decay, making them suitable for determining the dates of ancient artifacts. The answer is "rate of decay of the isotope."
The definition of mechanical power is
Power = (work done) / (time to do the work).
From that definition, it looks pretty much like the power of a machine
depends on work and time.
Answer:
At a greater value of pH, [H⁺] is really low.
Solution with pH = 8 has more [H⁺] than solution at pH =12.
Explanation:
pH = - log [H⁺]
10^-pH = [H⁺]
At pH = 8, [H⁺] = 10⁻⁸ → 1×10⁻⁸ M
At pH = 12, [H⁺] = 10⁻¹² → 1×10⁻¹² M
In conclussion, at a greater value of pH, [H⁺] will be really low.
Solution with pH = 8 has more [H⁺] than solution at pH =12.
