Answer: White blood cells help the immune system and help fight infection and disease.
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:
(a) 4 %; (b) 5 %
Explanation:
We need a Cu-Ag phase diagram to answer these questions (see diagram). Yours may differ slightly from the one I used.
(a) Cu in Ag
The horizontal red line at 700 °C cuts the right-hand solvus at about 4 % Ag-96 % Cu.
At this point, copper is in equilibrium with the eutectic.
At 700 °C, the maximum solubility of Cu is about 4 % by mass.
(b) Ag in Cu
The horizontal red line at 700 °C cuts the left-hand solvus at about 5 % Cu-95 % Ag.
At this point, silver is in equilibrium with the eutectic.
At 700 °C, the maximum solubility of Ag is about 5 % by mass.
