A solution is prepared by mixing 100 mL of 1 M HCl and 250 mL of 5 M NaCl. What is the total volume of the solution?
olga55 [171]

Answer:

<u></u>

  • <u>350 mL</u>

Explanation:

Normally, in the neutralization reactions, that is how the reactions between and acid and a base are called, you assume additive volumes.

Additive volumes means that the <em>volume</em> of the final <em>solution</em> is equal to the sum of the separate volumes of the two solutions that are mixed.

It is not totally accurate, but it is a good approximation and for lack of additional data it is what is used.

Then, assuming additive volumes:

  • Total volume of the solution = 100 mL + 250 mL = 350 mL.

The detector used in this experiment is called a Flame Ionization Detector (FID). As the different sample components come out of
Damm [24]

Answer:

c. 2-methyl-1-butanol.

Explanation:

As depicted in the question; the number of electrons produced is straightforwardly relative and directly proportional to the content and substance of carbon in the atom. So 2-methyl-1-butanol has the most highest and noteworthy carbon content (5carbons) among the accompanying species. So it will generate and create the biggest detector reaction response.

What color would the methyl orange indicator turn in a solution with a pH of 2?
alexdok [17]

Answer:

The answer is red.

Explanation:

  1. Methyl orange is an organic dye that used as an indicator in acid-base titrations because its color is changed according to pH of the medium (acidic, neutral or basic).
  2. Methyl orange is red in acidic solutions, orange in neutral solutions, and yellow in basic solutions.

Since pH of the solution is 2, the solution is acidic, the color of the solution will be red.
