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.

Which of the following are trial procedures? Select all that apply.
mihalych1998 [28]

Answer:

The correct options are;

  • Jury selection
  • Opening statements
  • grand jury indictment

Explanation:

The above-selected options relate to the order of trial procedure in a Court of law. I will just give a summary of what transpires during the trial of a case.

Firstly, in a criminal case, before an accused person is brought to court, a charge is filed by the prosecution counsel against him. The defense counsel, on the other hand, prepares an application in defense and this is usually by way of a motion paper. A person is called an accused person because according to law, he is presumed innocent until proven guilty.

The charge is then read to him in the language he understands and his plea will be taken. He is to either plead guilty or not guilty. Depending on different jurisdictions, the jury is usually selected by way of summons. After this, Counsel on both sides (Prosecution and defense counsel) will begin with an opening speech by briefly summarizing the facts of the case, arguments they wish to canvass and the evidence that will be adduced to prove the case.

Furthermore, Examination-in-chief, Cross-examination, and Re-examination of witnesses on both sides will begin. After this, the case will be given to the jury to decide the case on its merits.
