Answer:
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
Explanation:
The Answer is D. a polymer is a substance that has a molecular structure consisting of a large number of similar units bonded together
The reaction is shown below,
Step 1: Hydration of Alkene: In first step
Ethene is hydrated to Ethanol through
Hydroboration Reaction.
Step 2: Oxidation of Primary Alcohol: In this step partial oxidation of ethanol is carried out using mild Oxidizing agent <span>Pyridinium chlorochromate (
PCC) and Acetaldehyde is produced.
Step 3: Reduction of Acetaldehyde followed by Oxidation: In this step, first acetaldehyde is reduced to
secondary alcohol using
grignard reagent. After that the sec. alcohol is oxidized to
ketone by using oxidizing agent CrO</span>₃.
Explanation:
brain and heart froce acts between two chloramine
The number of Atoms must be the same on both sides
