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!
C. Temperature. The greater the temperature of a substance the greater the average kinetic energy of the particles that made up the substance.
True, wetlands help to prevent flooding.
It is a mixture
Explanation:
Food coloring is able to separate into different dyes because it just a simple mixture of different color pigments.
Under a chromatogram the different colors will migrate relatively over an absorbent.
A mixture is an impure substance with the following properties:
- composition is indefinite as they are made up of two or more elements or compounds in any proportion by mass.
- They are able to retain their identities i.e physical properties are maintained.
- Their constituents reacts differently to changed conditions.
- They can easily be separated into constituent by physical methods.
