Liquid silver is less dense than solid silver, so the solid silver would sink
Answer:
A solution that is 0.10 M HCN and 0.10 M LiCN
. A solution that is 0.10 M NH3 and 0.10 M NH4Cl
Explanation:
A buffer consists of a weak acid and its conjugate base counterpart. HCN is a weak acid and the salt LiCN contains its counterpart conjugate base which is the cyanide ion. A buffer maintains the pH by guarding against changes in acidity or alkalinity of the solution.
A solution of ammonium chloride and ammonia will also act as a basic buffer. A buffer may also contain a weak base and its conjugate acid.
Answer:
This reaction is an hydration of alkenes and the major product is 3-ethyl-2-heptanol
Explanation:
In this reaction in the first step water is the nuclophile and the alkene is the electrophile. Then, the carbanion is the nucleophile and attacks a proton from the water forming the respective alcohol. This carbanionic compound is a reaction intermediary. You can see the mechanism in the picture.
Is that carbanionic compound who explained the major product because the more substituted carbanion the most stable intermediary. Thus, the 3-ethyl-2-heptanol intermediary is the most stable and this product is the major one.
I hope it helps!
