A chemical plant produces ammonia using the following reaction at a very high temperature and pressure. Which design issue is mo
Lorico [155]

Answer:

D. The equipment needed to accommodate the high temperature and pressure will be expensive to produce.​

Explanation:

Hello!

In this case, for the considered reaction, it is clear it is an exothermic reaction because it produces energy; and therefore, the higher the temperature the more reactants are yielded as the reverse reaction is favored. Moreover, since the effect of pressure is verified as favoring the side with fewer moles; in this case the products side (2 moles of ammonia).

In such a way, the high pressure favors the formation of ammonia whereas the high temperature the formation of hydrogen and nitrogen and therefore, option A is ruled out. Since the high pressure shifts the reaction rightwards and the high temperature leftwards, we would not be able to know whether the reaction has ended or not because it will be a "go and come back" process, that is why B is also discarded. Now, since hydrogen and nitrogen would be the "wastes", we discard C because they are not toxic. That is why the most accurate answer would be D. because it is actually true that such equipment is quite expensive.

Best regards!

Alchemist made which of the following contributions to the development of chemistry?
a_sh-v [17]
Alchemists advanced the tools and procedures for working with chemicals. Alchemists also developed methods for sorting out mixtures and cleansing chemicals. They designed equipment that is still in use today including beakers, flasks, tongs, funnels, and the mortar and pestle. Also, Alchemists backed to an unbelievable variety of what would later be acquainted as chemical industries: basic metallurgy, metalworking, the invention of inks, dyes, paints, and cosmetics, leather-tanning, and the preparation of extracts and liquors.

Vlad1618 [11]
<h2>The isotopes of an element all have the same __(atomic, mass) __number, but they have different __(atomic,mass)__numbers.</h2>

Explanation:

The isotopes of an element all have the same __atomic  number  __, but they have different __mass __numbers.

The isotopes have same atomic number that is :

  • Same number of electrons
  • Same number of protons
  • same electronic configuration
  • same valence electrons
  • same valency
  • same symbol

The isotopes have different mass number that is :

They differ in number of neutrons .

For example : Isotopes of hydrogen are : H₁¹ , H₁² , H₁³

                       isotopes of Oxygen is : O¹⁶ , O¹⁷, O¹⁸
