The three traditional states of matter are solid, liquid, and gas.
A state of matter would be considered a physical property as it does not change the chemical composition of the substance and is reversible.
Ex) Freezing water will turn it to ice. The ice is still water and therefore, has not changed chemically. If we warm the ice, it turns to water. That reaction is then considered reversible.
Hope this helped :)
Answer:
Two design criteria for the design of the ammonia making process are;
1) Sustainable hydrogen production by renewable energy
2) Sustainable use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water
Explanation:
Ammonia is produced from natural gas in the following process;
H₂ + RSH → RH + H₂S
H₂S + ZnO → ZnS + H₂O (Waste water)
CH₄ + H₂O → CO + 3H₂
CO + H₂O → CO₂ + H₂
Ammonia is then produced by reacting the produced hydrogen with nitrogen in the presence of a catalyst in a process known as the Haber-Bosch process as follows;
3H₂ + N₂ → 2NH₃
The
The design criteria for the design of the ammonia making process therefore as follows;
1) Sustainable use of renewable energy to produce hydrogen gas from the electrolysis of water
2) Use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water.
Answer:
Naphthalene has C2-rotational axis passing through the C9-C10 bond. It has two C2-axes perpendicular to the principal C2-rotational axis (one is passing through the mid-point of the C9-C10 bond another passing through the midpoints of C2-C3, C9-C10, C6-C7 bonds).
