I would say D. Let me know if i am wrong.
Answer : Option B) Plant stomata opening and closing to maintain homeostasis.
Explanation : Claude Bernand was a French Physiologist who first discovered about "homeostasis" which is defined as the controlled stability of the internal milieu, or internal environment, of cells and tissues in plants.
In plants stomatal opening and closing was done for maintaining homeostasis with the external and internal plant environment.
When liquid evaporates we know that it's going from a liquid to a gas therefore going from an ordered state to a more chaotic disordered state meaning the entropy which is the measure of order, goes up. Since this is a spontaneous reaction at high temperatures and non spontaneous at low temperatures and free energy is negative for spontaneous then we can say at high temperatures free energy is negative and at high temps and positive at low temps. Also since evaporation requires energy to evaporate the enthalpy is positive.
Answer:
Reason Down below
Explanation:
It is important because when you make observation you get a clue sometimes and it reactants i feel like it also takes places with observation. :)
Answer:
dimethoxy(phenyl)methanol
Explanation:
For this question, we have to remember the <u>mechanism of the Grignard reaction</u>. In this case, <u>phenylmagnesium bromide</u> is our <u>nucleophile</u>, a carbo-anion is produced (step 1). Then this <u>carbo-anion</u> can <u>attack</u> the <u>carbonyl group</u> in the <u>dimethyl carbonate</u>, the double bond is delocalized into the oxygen producing a <u>negative charge</u> (step 2). Finally, with the addition of the h<u>ydronium ion</u> (), the anion can be protonated to produce the <u>alcohol</u> (dimethoxy(phenyl)methanol) (step 3).
See figure 1
I hope it helps!
