Answer:

With the phenol of the salicylic acid.

Explanation:

Hello,

In this case, we take into account that ferric chloride, FeCl₃, easyly reacts with phenol groups, in fact, that is one way to qualitatively substantiate the presence of phenols in an organic sample. Phenol groups are those hydroxiles (-OH) attached to an aromatic ring. Now, if FeCl₃ is added to a substance containing phenol functional groups, it will turn purple. For this case, since aspirin does not have any phenol group, in contrast to salicylic acid, which is used to produce aspirin, but actually has a phenol group, the aspirin sample will not react while the salicylic acid will turning purple, due to the aforesaid reason. Such purple color is shown off as a result of the formation of an iron-containing complex or chelant.

Best regards.

Answer:

coral bleaching is when the temperature of the water changes (even slight changes in temperature effect coral) and the coral reacts negatively to it causing it to die. unfortunately corals cannot recover once they have been bleached.

A ball is rolling across the floor. Every 3 seconds it travels 12 meters. Its speed, therefore, is 36 m/s. Is this problem solve

kirill [66]

No because you are supposed to do this

$d = t)v$
T for time and V for velocity or acceleration so what you do is take the two numbers

D= 3/12 it goes 12 meters every 3 seconds so you devide 12/3
$12 \div 3 = 4$
So for every second the ball roles 4 meters!
Hope this helps! :)

<h3>Entropy Change: What Is It?</h3>

Entropy change is a phenomena that measures the evolution of randomness or disorder in a thermodynamic system.
It has to do with how heat or enthalpy is converted during work.
More unpredictability in a thermodynamic system indicates high entropy.
Heat transport (delta Q) divided by temperature equals the change in entropy (delta S).

<h3>What causes variations in entropy?</h3>

When a substance is divided into several pieces, entropy rises.
Because the solute particles are split apart when a solution is generated, the dissolving process increases entropy.
As the temperature rises, entropy increases.
