The last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).
<h3>What is an experiment?</h3>
The essence of an experiment is to be able to establish a cause and effect relationship. It is only when we carry out a carefully controlled experiment that we can say that x causes y because the data would support our findings.
After, we have carried out an experiment, the next step is to put the evidences together and then try to arrive at a logical conclusion for the experimental procedure.
Thus the last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).

Answer:
Bonds are broken and new bonds are formed during chemical reactions only.
Explanation:
- A physical change in a substance doesn't change what the substance is.
- In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
- Physical changes can be reversed, chemical changes cannot be reversed with the substance changed back without extraordinary means, if at all. For example, a cup of water can be frozen when cooled and then can be returned to a liquid form when heated.
So, the right choice is:
Bonds are broken and new bonds are formed during chemical reactions only.
because the reaction can be caused by seemingly nothing but isnt, like how White phosphorus ignites if exposed to earths atmosphere. plz mark brainliest
Answer:
(a). Increase in the rate of Reaction.
(b). Increase in the formation of the alcohol.
(c). rate of Reaction will increase that is to say more of the alkyl azide will be produced.
(d).rate of Reaction will increase that is to say more of the alkyl azide will be produced.
(e). rate of reaction increases because of carbocation.
Explanation:
Important thing to note is that this reaction proceed with an SN1 mechanism.
Therefore; the rate of reaction depends solely on the concentration of alkyl azide.
(a). The concentration of the alkyl chloride is increased: rate of Reaction will increase that is to say more of the alkyl azide will be produced.
(b) The concentration of the azide ion is increased: the effect is that there will be an increase in the formation of more of the alcohol.
c) The alkyl bromide is used instead of the alkyl chloride: the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.
(d) The reaction is carried out in 1:1 acetone water instead of pure water: the effect is that there will be the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.
(e) The alkyl chloride shown below is used instead of cumyl chloride: rate of reaction increases because of carbocation.
