Answer:

The analysis is: acetic acid will be too low because of the acid that may still be in the water.  

Explanation:

We know that the amount of acetic acid in vinegar is determined by the volumetric titration of acetic acid with standardized NaOH solution; because it doesn't affect the number balance of hydronium and hydroxide ions.

This percent by mass of acetic acid will be too low because of the acid that may still be in the water.  

Now if the deionized water is contaminated in this case with carbonic acid, so there would be a consumption of a higher amount of NaOH for neutralization as a result. Therefore, the amount will depend on many factors.

Mashutka [201]

A) During this time period, Africa was being explored and colonized by various European powers. While the Portuguese were the first to arrive, soon other European powers joined them, such as the French and the Dutch. In these early years of colonialism, these powers fought for dominance in Africa, and borders and areas of control changed frequently.

B) In this passage, we see evidence that supports the idea of the continuous development of the Atlantic in the seventeenth century. We learn about elaborate constructions that the European colonists established along the Atlantic Coast of Africa. We also learn about the importance of trade in this region and of the competition between different European powers.

C) According to this passage, Jean Barbot was a French Protestant and agent of the chartered Senegal Company. In the second paragraph, he makes it clear that this admiration and support lies with the French, and not with the Portuguese. This could be attributed to him being a Protestant. Because of his beliefs, he might feel more attracted by a Protestant nation (the Netherlands) than by a Catholic one (Portugal).

yulyashka [42]

Answer:

The answer is the attribution dispositional and situational

Explanation:

The attributions refer to the judgments that people make on behavior, and this depends on how people perceive the situation.

<em>The attributions are divided into two: </em>

  • Dispositional Attribution
  • Situational Attribution

It is known as dispositional attribution when we explain the behavior of people according to their personality characteristics, we make a judgment for the information that we know about them, obtaining an internal attribution about the behavior of the person in the situation.

For example in the case of Gamiel, he did not leave a tip for the waiter and Aliyah attributes this behavior based on the information he knows about Gamiel, who possibly only tips expensive places, Aliyah justifies the action through dispositional attribution.

The opposite of the internal attributions are the situational attributions, these justify the behavior of the people to external events that cannot be controlled but that cause an effect on the behavior of the person. For example, Gamiel and Aliyah had the experience of having a horrible service by the waiter, for which Gamiel does not leave a tip, Aliyah justifies this action to the lousy service received, here she is using situational attribution.

<em>I hope this information can help you.</em>
