Answer:
- Volume is a physical property of an object.
- One unit of volume is the milliliter.
- Liquids and solids have constant volumes.
Explanation:
Answer:
A battery is a device that stores chemical energy and converts it to electrical energy.
Explanation:
Bromine has 35 protons, and in this case 46 neutrons, so 35 + 46 = 81
Therefore, the symbol is (subscript 35)(superscript 81) Br.
Answer:
Substitution.
Explanation:
Claisen reaction was first published in 1887 by a prominent German chemist known as Rainer Ludwig Claisen.
A Claisen reaction is a nucleophilic substitution in which an enolate is the nucleophile. It's typically a reaction of two molecules of an ester to form a β-keto ester, in the presence of an alkoxide base. Thus, a Claisen reaction is simply a characteristic condensation reaction of esters through a nucleophilic carbonyl substitution with an enolate such as a ketone enolate or an ester enolate.
Furthermore, a Claisen reaction results in the formation of a carbon-carbon bond in the presence of a strong base to yield a β-keto ester.
