Answer: Habers process is the industrial process used for the production of ammonia
Explanation:
Habers process is the industrial process used for the production of ammonia. It uses hydrogen from natural gas and nitrogen mainly from atmosphere under extremely high pressures (150-200atm) and moderately high temperatures 
.
The catalyst used in Habers process is iron.
The balanced chemical reaction is:
C is the answer I took a test with the same answer
Cell wall:
-acts like a skin
- most selectively controls what is inside and outside of the cell
-rigid
Cell membrane:
-gives a plant cell
-not rigid
Structure along with ¹H-NMR is shown below.
Signal for Hₐ; Based on multiplicity of of the peak, a
Singlet peak (the only singlet peak present in spectrum) at
2.2 ppm was assigned to Hₐ. As the methyl group in not coupling with any other proton so it gave a singlet peak.
Signal for Hb; Based on multiplicity of of the peak, a
Quartet peak (the only quartet peak present in spectrum) at
2.4 ppm was assigned to Hb. As the methylene group in coupling with methyl group having three protons so it gave a Quartet peak.
Signal for Hc; Based on multiplicity of of the peak, a
Triplet peak (the only triplet peak present in spectrum) at
1.1 ppm was assigned to Hc. As the methyle group in coupling with methylene group having two protons so it gave a Triplet peak.
The energy input into the icemaker is used to drive the cooling system. The equipment has a radiant that requires to be run by electricity. Liquid ammonia in the radiant tubes of the icemaker pick up heat from the water and evaporate. As the ammonia evaporates and moves to the radiator, the action of the fan cause it to lose heat to the environment. The ammonia cools and becomes liquid and moves back to collect more hest from teh water. This cycle continues unilt the water turns to ice.
