The answer is <span>Plastics, Medicine, Clothing, Paper. </span>Coal is used in the making of Plastics, Medicine, Clothing, Paper. Some important users of coal include alumina refineries, paper manufacturers, and the chemical and pharmaceutical industries. Thousands of different products have coal or coal by-products as components: soap, aspirins, solvents, dyes, plastics and fibres, such as rayon and nylon.
Answer:
d. Adding 5% HCl solution to the crude reaction mixture will protonate aniline increasing its solubility in the aqueous solution.
Explanation:
On this case, we have to check the <u>structures of each compound</u> (figure 1). For naphthalene we dont have <u>any functional groups</u> therefore, the addition of HCl or NaOH it will not affect naphthalene so <u>we can discard "B" and"C".</u>
When we add HCl solution we will have the production the presence of this <u>hydronium ion will protonate the acid</u>, so we can <u>discard a.</u>
<u />
Finally, for d when we add the <u>hydronium ion will react with aniline</u> (a base) and will produce an <u>ammonium ion</u>. This ammonium ion have a <u>positive charge</u>, therefore the <u>polarity will increase</u> and the molecule would be more soluble on water (figure 2).
I hope it helps!
Answer:
Neutralization is when the pH (power of hydrogen ions) of a solution is at 7 (considered neutral in the pH scale). This means it's neither acidic nor basic and is neutral. In order to neutralize an acidic solution, you pour in the same amount of a strong base. And in order to neutralize a basic solution, you pour in the same amount of a strong base.
A neutralization reaction will give you salt and water. A common neutralization reaction could be:
HCl (strong acid) + NaOH (strong base) ----> NaCl (Salt) + H2O (water)
Answer:
acetic acid
